CITES recognizes important marine species

You might think that sharks are a predator that we want to eradicate, but that’s far from the truth of the matter. For a healthy ocean we need the top predator. For 5 species of sharks – oceanic whitetip, scalloped hammerhead (pictured below), great hammerhead, smooth hammerhead, and porbeagle sharks – there was some inspiring news during the 16th meeting of the Conference of the Parties for the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Proposals were adopted that would give them greater protection and provide them with less risk from overfishing (According to the Guardian, “Those fishing for oceanic whitetip, porbeagle and three species of hammerhead shark will now require strictly controlled permits to export the fins”) for these sharks. However, the move will need to be adopted completely by a final plenary session scheduled for Thursday. It’s a particularly significant move considering CITES meetings take place every three years and that CITES has not traditionally leaned towards protecting marine species due to the intense political and economic issues that are related to fisheries issues. According to the Washington Post, “Elizabeth Wilson, who manages the Pew Environment Group’s global shark campaign, said the broad array of countries backing the proposals this year helped produce success this time around”.

Globally,  sharks are in peril and overexploited due in major part to a voracious demand for shark fins, especially in Asian markets, since it’s the primary ingredient in shark fin soup (more affordable and more popular than ever at Asian weddings). While it might be a difficult culture shift for the expanding Asian middle class (a delegate at CITES stated, “It would be like telling the French not to have champagne at their wedding“), ultimately it’s what has to be done since shark populations have fallen to such low levels. As they saw off the coast of North Carolina once sharks were overfished rays thrived and then destroyed the lucrative bay scallop fishery. Here is another resource outlining the importance of sharks to the ocean ecosystem.

Grab a Shark Stanley printout and show your support for shark conservation by participating in this initiative of the Shark Defenders. Help them reach their goal of collecting at least 5,000 photos! It’s important to gather these photos in time for the upcoming Convention on International Trade in Endangered Species (CITES) meeting in March. Check out all the places Shark Stanley has been on the Instagram and Facebook pages!

Why is shark conservation important?

Sharks are in peril and overexploited due in major part to a voracious demand for shark fins, especially in Asian markets. Shark finning is the removal and retention of shark fins and  discarding the body at sea (The animal is often alive when tossed back into the water!). The Pew Environment Group estimates that “Up to 73 million sharks are killed every year to primarily support the global shark fin industry”. The underlying problem is that sharks grow slow, mature late, and produce few young over their long lifetime – meaning their populations recover slowly once depleted. Depleted populations affect the health of the entire ocean ecosystem. Here are some examples on how it’s all connected:

  • Sharks help maintain healthy fish stocks because they prey on vulnerable sick, diseased, or old animals – thereby, preventing disease or sickness from spreading.
  • Sharks have the ability to ensure we always have vital seagrass beds by controlling their prey, dugongs and green sea turtles – which forage in these beds. Healthy seagrass beds are essential for maintaining good water quality in our estuaries.
  • Sharks are the #1 draw for many divers providing a booming tourism industry to remote places that might not otherwise have a good economy.

Do you know your seafood?

With the holidays right around the corner there will no doubt be plenty of indulgences. It is important to keep in mind that seafood can also be considered an extravagance if you’re choosing an unsustainable option to serve or taste. Did you know that the global fishing fleet can catch up to two and a half times what the ocean produces? 80% of fish stocks are harvested at or above maximum sustainable yield? Check out this infographic by One World One Ocean that was released last month for National Seafood Month  for those facts and a whole lot more, including 1) fish on the red list (not good) and green list (good), 2) reasons why these fish are on these lists, 3) chefs and grocers to support, and 4) important guides to download.

Indian food is everywhere. You go to any corner of the world and you’ll find an Indian Restaurant serving the taste of India. Moreover, Indian Food is heartily welcomed and loved by everyone. But very few know that Indian food offers more benefits to your health than satisfy your appetite. Tamarind Cuisine provides the best Indian Fine Dining in Orlando.

Very often people think of Indian food as a hot, spicy, full of gravy and heavy food which is good for the taste buds but not for the health. But that’s not true, in fact, Indian Food can be the most healthy food one can ever have considering all those fresh vegetables and authentic spices added in the dishes. All these authentic spices used in Indian food are in fact very important for your health. Most of us might haven’t noticed this yet but that’s true and to understand more, let’s dive deep and know more about the Indian Cuisine:

  • Most of the Indian Cuisine recipes include the most refreshing array of vegetables and fruit cooked in different ways that help retain their freshness and nutrients. A lot of cooking processes practiced in other parts of the world tend to cause these refreshing vegetables and fruits to lose their nutrients and other health benefits but this is not the case with Indian Food. It allows you to enjoy their health benefits in a more enjoyable way than their original form.
  • It always uses fresh ingredients. It also involves making dishes from scratch leaving less space for the use of preservatives and artificial ingredients. This makes the Indian Food way far healthier.
  • Indian Cuisine widely uses spices like turmeric, Ajwain, ginger, garlic, cardamom, and green chilies. All of them have some or other medicinal and healing properties, which are very beneficial for your health. The spices used to make the Indian Food are not just offering some savory taste but also are actually good for the health.
  • Authentic Indian meals are abundant carbohydrates, proteins, fats, and fibers, which are highly needed for a balanced diet and a healthier life.
  • Another reason why Indian Food is so important for your health is the use of yogurts and other dairy products. These are often used in Indian food and many dishes are made from fermented milk, which keeps the digestive tract healthy. They also come with lots of calcium, which means eating them regularly can help you have healthier bones and overall body fitness.

There is more to Indian food and if you might think to explore the delicious and savory Indian Food Orlando, then Tamarind is your only destination that offers the best and authentic Indian Food in Orlando, Florida.

Myth debunked: Delaware Bay not an annual pit stop for all shark species

A fan of Beach Chair Scientist on Facebook recently asked me to demystify a rumor she had heard. This is what she wanted to know: “I was told that over the course of a year, at least one of every species of shark can be found in the Delaware Bay. Do you know if this is true?” I asked Jim Wharton, frequent BCS guest blogger and shark expert, to tackle this one. This is his response.

Sadly, it is not true. There are at least 500 species of sharks in the ocean. They range in size from six inches to sixty feet. They can be found in water ankle deep to the abyssal depths … from the tropics to polar ice caps. To find a nexus point like this anywhere in the ocean would miraculous. Sharks are just too diverse.

Still, there are sharks in Delaware Bay. Anglers might encounter sand tigers, sandbar (brown) sharks, smooth dogfish, and spiny dogfish with other occasional visitors (including at least one record of a juvenile white shark). In fact, the National Marine Fisheries Service has identified the Bay as ‘Essential Fish Habitat’ for several species of Federally protected ‘Highly Migratory Species’ including sandbar sharks, sand tigers, and smooth dogfish. This designation recognizes the critical foraging and nursery habitat the Bay provides for these important species.

Dr Dewayne Fox’s lab at Delaware State University is working to create a conservation plan for the sand tiger sharks in the Bay. These distinctive, snaggletoothed sharks are very popular in public aquariums. Despite their fearsome appearance, they rarely interact with people. Sand tigers are top predators and represent a critical keystone species in the ecology of Delaware Bay. Dr. Fox and his students are implanting passive acoustic transmitters inside sharks to better understand their movement patterns. The transmitters emit an identifiable ‘ping’ that is collected by strategically located listening stations to help researchers track the animals in the Bay. Understanding how the sharks use the Delaware Bay is essential to identifying critical habitat for protection. You can learn more about Dr. Fox’s work here.

Sand tigers, by way, are freakish and fantastic creatures that are well-worth saving. No sharks have swim bladders, but sand tigers gulp air at the surface to make themselves neutrally buoyant. Sand tigers are one of many species that explode the myth of the shark in constant motion, frequently found lying near-motionless on the sandy bottom. Sand tigers are fish-specialists, with more-than-a-mouthful of narrow, prong-shaped teeth for grabbing slippery prey. They like to hang-out in large aggregations and may actively cooperate to herd schools of fish. Most fantastic of all…baby sand tigers are “embryonic cannibals.” Sand tiger embryos quickly exhaust their meager yolk sacs and start in on the undeveloped eggs…but they don’t stop there. The largest embryo in each uterus (yes, sharks have two) attacks and consumes its brothers and sisters in the ultimate form of sibling rivalry.

Good references for more on sand tigers:

  • Compagno, L. J. V., Dando, M., & Fowler, S. L. (2005). Sharks of the world. Princeton: Princeton University Press.

10 fish you don’t see during Shark Week

I confess. I’ve given up on Shark Week. It took 25 years to shake me, but for the first time I can remember, I won’t be watching. When I was 16, you couldn’t schedule enough great white and shark attack programming to satisfy me. Danger Beach, Vic Hislop, Air Jaws … it was all good. It’s obviously a winning formula for Discovery, but for me, it’s just not enough any more.

There are 500 species of sharks out there. Probably more. There are so many stories to tell. Here are ten you (probably) won’t see this year during Shark Week:

1. Ocean giants. The two largest fishes on Earth are sharks. Thirty-foot, plankton-eating basking sharks can filter a swimming pool of seawater every hour through sieve-like gill rakers in their throats. Whale sharks grow bigger than school buses, and gather by the hundreds in the waters off Mexico’s Isla Holbox and other global hotspots for seasonal feasts of zooplankton or fish eggs. Despite surviving on this surface-dwelling diet, researchers have also tracked whale sharks to depths of more than 6,000 feet. Why?

2. Glowing deepsea sharks. Lantern sharks glow in the dark and hide in the light. Many species of deepwater sharks, including the lantern sharks, are bioluminescent (i.e., they create their own light). Some of these sharks can even project light from their bellies that closely matches the light filtering down from above, erasing their silhouette. They also happen to be beautiful little creatures with fantastic names, like the velvet belly shark, the taillight shark, and the splendid lantern shark. Wouldn’t you like to meet a splendid lantern shark?

3. Cookie cutters. Shark geeks know all about the cookie-cutter shark, but I always forget that they’re not exactly famous…yet. A big cookie-cutter is less than two feet long and yet they’ve been known to feed on tuna, seals, dolphins, and whales…yes, whales. It’s a neat trick. The cookie-cutters sneak up on large prey, attach themselves with fat, sucking lips and twist and thrash until they pull free a round plug of flesh. These little sharks have a remarkable set of jaws with positively enormous teeth. In fact, the cookie-cutters have the largest tooth-to-body-length ratio of any shark (including the great white).

4. Wobbegongs. Can I interest you in a flat shark with patterns like bad 70’s wallpaper and a mustache that would put Tom Selleck to shame? Wobbegongs are bottom-dwelling masters of camouflage with ornate, branching lobes hanging from their upper jaws that look enough like algae or kelp to attract unsuspecting fishes and crustaceans. Wobbegongs lie in wait until their prey gets just a little too close, then erupt in an explosion of tassels and teeth.

5. Hammers and saws. You may have seen hammerheads during Shark Week, but have you ever seen a winghead shark? Wingheads have ‘hammers’ nearly half their total body length. To what benefit? Don’t know. What’s stranger than a hammerhead? How about a sawshark? Imagine a shark, with a chainsaw blade attached to its face and two long noodle-like nasal barbels for detecting buried prey. You can’t make this stuff up.

6. Here be goblins. All sharks have protrusible jaws. Their choppers are loosely attached to their skull, which allows them to push their jaws forward to get a little extra reach, or to create suction. Goblin shark jaws aren’t just extendable, they’re spring-loaded. Elastic ligaments are stretched taught when the shark’s mouth is closed and slingshot the jaws forward as they open. Goblins may need the extra reach to get out from under their long, wide rostrum…which looks a little like an ironing board (at least to me).

7. Helicoprion. You’ll hear plenty about the mega-monstrous megalodon this week, but I’d rather hear a little more about a real pre-historic elasmobranch enigma. Helicoprion had a strange spiral tooth whorl that early paleontologists had no idea what to do with. Some placed it in the sharks’ mouth, some on their dorsal fin. Some suggested it shot out like a frog’s tongue to ensnare their prey. Though speculation seemed to have settled on a lower jaw placement, at least one author suggests the teeth may have resided in Helicoprion’s throat.

8. The shark that walks like a dog. One of my favorites is the epaulette shark, a charming little carpet shark with a distinctive ocellated spot on its flank and a peculiar habit of locomotion. Epaulettes scamper across the reef on large pectoral and pelvic fins. Truthfully, these sharks look more like salamanders than dogs as they wriggle over complex coral reef habitats…and maybe a little like pigs as they root around in the substrate searching for food with their nasal barbels.

9. The sharks who’re named for cats. The catsharks are the largest family of sharks, and boast some of the strangest and most beautiful sharks in the sea. Some catsharks sport snappy colors and patterns like the striped pajama catshark and the chain dogfish (which is actually a catshark). Others are just bizarre, like the spatulasnout and lollipop catsharks, two hyper-specialized deepsea rarities. The aptly named swell shark gulps seawater (or air) and inflates like a pufferfish when threatened.

10. Sleepers. There’s not only diversity in size, shape, and appearance; there is also surprising variety in the ranges and habitats of sharks. Would you expect to find sharks beneath arctic ice sheets? Greenland sharks and Pacific sleepers are lumbering, flabby, but impressive beasts, surviving and thriving where you’d least expect. Stomach contents range widely from giant squid to halibut to seal and whale blubber to at least one (probably apocryphal) account of an entire reindeer.

That’s ten, but I’m still ignoring that other elusive plankton-feeding giant, the megamouth shark, not to mention the long-tailed threshers, the surrealistic rough sharks, frilled sharks, cowsharks, spotted zebra sharks, and puffadder shysharks. I won’t be watching, so if you hear more than a gee-whiz sound bite on any of these sharks, you’ll have to leave a comment to let me know and my faith will be restored.

I will credit Shark Week for creating a lot of excitement about sharks once a year. Some of the kids thrilled by the antics of bait-addled and target-tempted whites, tigers and other super predators will go on to become scientists, conservationists and marine educators…but many others will merely have tired shark stereotypes newly instilled or freshly reinforced. The challenge falls to educators, researchers, and shark enthusiasts to pick up the gauntlet and fill in the blanks for those viewers who just don’t know what they’re missing when it comes to the unappreciated (but critically important) diversity of sharks.

Sink your teeth into this: 20 facts about shark teeth

Are you ready to sink your teeth into Shark Week 2012? Here are 20 facts about shark teeth to get you started. Discovery Channel’s annual event looks like it will quite the extravaganza  for its 25th year. Andy Samberg from Saturday Night Live has been brought in as the official ‘chief shark officer‘. I have my reservations about the summer ritual now as a marine conservationist (Read this article I resonated with last year “Should Shark Week Focus On Conservation?” from Care2.org), but love that it’s an event that brings people together and creates an interest in the marine ecosystem. I have many fond memories of my brothers, parents, and I slowing down at the end of summer to watch sharks in a way we never could from the shoreline.

1. Shark teeth are not attached to gums on a root like our teeth.
2. Sharks typically lose at least one tooth per week.
3. Sharks lose their teeth because they may become stuck in prey or broken and forced out.
4. Shark teeth are arranged in neat conveyor belt rows and can be replaced within a day of losing one.
5. Sharks average out to 15 rows of teeth in each jaw. Although most have 5 and then there is the bull shark that has 50 rows of teeth.
6. Shark teeth are popularly found as beach treasures because sharks shed 1000s of teeth in a lifetime. Although, don’t get yourself in trouble if you decide to collect them. Recently, over 2,400 shark teeth were confiscated from a passenger in India (shark teeth are an illegal import prohibited under the Wild Life Protection Act of 1972).
7. Well after a shark dies and its body decomposes its teeth will fossilize.
8. Fossilized shark teeth are not white because they are usually covered with sediment (which prevents oxygen and bacteria from getting to them).
9. It takes about 10,000 years for a shark tooth to fossilize. The most commonly found shark teeth fossils are from 65,000 year ago (the Cenozoic era).
10. Venice, FL (on the Gulf of Mexico) calls itself the “shark tooth capital of the world”.
11. Sharks are born with complete sets of teeth and swim away from their mother to fend for themselves.
12. A shark’s tooth shape is dependent upon its diet. For instance, the shortfin mako razor like teeth tear flesh, the tiger shark has piercing teeth to cut flesh, and the zebra shark has dense flattened teeth because it feasts upon mollusks.
13. Whale sharks have 3,000 little teeth that are of little use. They’re filter feeders that find food by sifting through their gills.
14. The tooth of the megalodon range from 31/2 – 7 inches long and can weigh more than a pound!
15. Shark teeth were recently discovered to contain fluoride.
16.  Sharks do not suffer from cavities.
17. The inside of shark and human teeth contains a soft mineral known as dentin.
18. The coating of shark teeth is acid resistant and less water soluble than our teeth.
19. Shark teeth and human teeth are equally as hard.
20. Even though many sharks have sharp teeth that could inflict a wound to humans, sharks should always be treated with respect.

What they’re into … with David Shiffman (@WhySharksMatter)

This is a series I’ve been featuring each Tuesday this summer to get a special sneak peek at the many different personalities behind the scientists, activists, and educators (including bloggers) who play an integral role in the marine science conservation field. It’s essentially an extension of the overwhelmingly popular and well done Tumblr blog, This Is What A Scientist Looks Like, (BCS was featured in April!) which sets out to illustrate that scientists are not just crazy haired nerds in lab coats. I’ve sent a list of 15 random questions and asked that each person share at least their answers to 5 of them. This week features David Shiffman of Southern Fried Science and I am so glad he agreed since I know this crowd loves shark talk.

David with a sandbar shark in Charleston harbor

David is a Ph.D. student at the University of Miami’s Abess Center for Ecosystem Science and Policy. His research focuses on shark behavior, ecology, and conservation, and he has interacted with over 2,500 sharks on three continents. David writes about shark science and conservation topics for the marine biology blog Southern Fried Science, and is active on Twitter @WhySharksMatter. Additionally, David has a B.S. with distinction in Biology from Duke University, and a Masters in Marine Biology from the College of Charleston. If you and your class or community organization are interested in joining David and the RJ Dunlap Marine Conservation Program for a shark tagging expedition in the Florida Keys, please let him know! These are the best replica watches.

What is your favorite Sunday breakfast?
When I lived in Charleston, SC, crab cake eggs benedict. They don’t have that here in Miami, but there’s a place around the corner from my apartment that makes peanut butter and chocolate chip pancakes.

What’s your favorite midnight snack?
Homemade cookies. My first word was “cookie”.

Are you a night owl or a morning person?
Although field research often involves getting up at 4:00 a.m., I am not a morning person. I enjoy having morning people in the car with me when I have to drive to our research locations before the sun rises, though.

Which sitcom character do you relate to?
I’m not sure if “Glee” counts as a sitcom, but if so, Sue Sylvester. If not, Jack Donaghy from “30 Rock” or Ron Swanson from “Parks and Recreation”.

What is your favorite scent?
Bacon. Or maybe popcorn. Actually, they make bacon-flavored popcorn now. It’s surprisingly not gross.

What three things would you take with you to an island?
If this is an island I’m vacationing on, I’d bring snorkel gear, beer, and beer. If this is a deserted island I’m going to be stranded on, I’d bring a satellite phone, a GPS, a fly fishing starter kit, and a boat to help getting un-stranded.

Are you a cat person, dog person, or neither?
I am definitely a dog person. My new puppy Magnolia is sitting at my feet in my office as I answer these questions.

Bonus random fact you’d like to share about yourself?
There is a hot dog named after me (the Shiffman) at the hot dog stand on Duke’s campus. It is a hot dog served on a twinkie.

Yum! Thanks for the amazing idea for dinner tonight, David! Also, thanks for sharing your personality with us. For more ‘What they’re into …’ with other ocean folks click here.

What’s your favorite marine mascot?

We took our daughter to her first major league baseball game this weekend. I will never forget her cheery face when she’d point at the bright orange and black cartoon Orioles on fan’s shirts and say, “buuurrd?” The Phillies lost so it wasn’t the best experience we could have hoped for at Camden Yards, but overall my little family had an enjoyable time (also, impressive despite the 90 degree weather).

Needless to say, the day got me thinking about marine-themed mascots for major league sports in the U.S. This is a list of 9 marine mascots that might inspire your little marine biologists to follow baseball, hockey, or football or conversely that could get your little sports fan into science. I suppose if you’re a teacher, these mascots are also useful teaching tools to introduce different biological units (Ok, I am not certain what lesson you’d ever need Raymond the Seadog to introduce).

  1. T.D. the Dolphin (Miami Dolphins – NFL)
  2. Blitz the Seahawk (Seattle Seahawks – NFL)
  3. Lou Seal (San Francisco Giants – MLB)
  4. Iceburgh the Penguin (Pittsburgh Penguins – NHL)
  5. Fin the Whale (Vancouver Canucks – NHL)
  6. Raymond the Seadog (Tampa Bay Rays – MLB)
  7. Billy the Marlin (Miami Marlins – MLB)
  8. S.J. Sharkie (San Jose Sharks – NHL)
  9. Al the Octopus (Detroit Redwings – NHL)

From what I uncovered, the national basketball association is void of ocean animals as mascots. Please feel free to comment if you can think of another or just let me know if you have a favorite. Lastly, does anyone know where the Phillie Phanatic is originally from?

How do fish give birth? Revisited

From time to time, I like to revisit the more popular posts and present either new material or the material in a new format. Below is a simplified understanding of the three general ways that fish give birth (i.e., Within each category below there are sub-categories that I did not get into here). Please feel free to comment below or send me an email at info@beachchairscientist.com if you have any additional questions.

What are the fastest fish in the sea?

Not too long ago, I provided an update on the fastest fish in the sea, the Indo-Pacific sailfish (Istiophorus platypterus). I thought it would be interesting to do some research on how fast this fish is in comparison to other animals on land and in the sea and create a graphic to illustrate it.  First, some notes, there are some outliers I left off the chart. For instance, the Peregrine falcon (Falco peregrinus) at 325 miles per hour (mph), as well as pretty much the entire family of swifts (Apodidae) averaging a 106 mph flying speed. Also, I am certain there are many other species of terrestrial and flying animals that can be included in this list, I only added a few to compare. Please feel free to comment below or send me an email at info@beachchairscientist.com if you have something to add to the list!

THE LIST

Peregrine Falcon (Falco peregrinus) 200 mph
Swift (Apodidae) 106 mph
Sailfish (Istiophorus platypterus) 70 mph
Cheetah (Acinonyx jubatus) 70mph
Pronghorn antelope (Antilocapra americana) 61 mph
Striped marlin (Tetrapturus audax) 50 mph
Wahoo (Acanthocybium solandri) 48 mph
Southern blue fin tuna (Thunnus maccoyii) 47 mph
Yellow fin tuna (Thunnus albacares) 46 mph
Blue shark (Prionace glauca) 43 mph
Ostrich (Struthio camelus) 43 mph
Bonefish (Albula vulpes) 40 mph
Swordfish (Xiphias gladius) 40 mph
Tarpon (Megalops cyprinoides) 35 mph
Tiger shark (Galeocerdo cuvier) 33 mph
Hawk moth (Sphingidae) 33 mph
Human (Homo sapiens) 27 mph
