Have you visited the Sant Ocean Hall?

January 22, 2013 by 1 Comment

I’m lucky enough to live and work in the DC metro area, one of the biggest reasons I love this city (besides being able to feel the thrill and excitement of the Inauguration this past weekend) is the access to free museums. If you’re an ocean lover you might be surprised to know that there are some great spots to visit in DC in between all of the historical monuments you’re checking out. One of my favorite spots to check out on a rainy afternoon in the extension of the National Aquarium on 14th Street. Another fantastic spot would be the Sant Ocean Hall in the Smithsonian Institute’s National Museum of Natural History. It is the largest and one of the newest exhibits in the museum and contains over 674 specimens, including a replica of a 45-foot-long North Atlantic Right Whale (pictured below), fish x-rays, a scalloped hammerhead (below),  and a giant squid! I cannot wait to visit next month when there’s an exhibit of underwater pictures by Brian Skerry (check out his National Geographic Ocean Soul book here). The next time you’re in DC you have to make a point to visit, as they say “like the real ocean, the deeper visitors explore – the more they will discover”. My two-year old loved all of the interactive exhibits and the space was buzzing with enthusiastic school children. I was particularly happy that the exhibit hall was large enough that we were never on top of anyone and could always escape the ‘enthusiastic school children’. Here are some pictures from my visit on Friday.

Sink your teeth into this: 15 facts about orcas

January 17, 2013 by 1 Comment

killerwhales_southernresidentsI won’t lie. My inspiration for this post is my obsession with this season’s Top Chef,  set in Seattle, WA (Bye, Kristen! I was very sad you went home). Anyway, here is a list of some captivating facts about the dominating marine mammal (the last one is the most important!).

  1. The killer whale, or orca, is a toothed whale and a kind of dolphin – in fact, it’s the largest of all the dolphins!
  2. Their Latin name, Orcinus orca, means ‘Greek god of the underworld’.
  3. Male orcas can average up to 22 feet in length and can average up to 12,000 pounds.
  4. Female orcas can average up to 19 feet in length and can average up to 8,000 pounds.
  5. Newborn orcas average up to 8 feet in length and weigh up to 400 pounds.
  6. Orcas typically swim to speeds of 3 to 4 miles per hour, but can reach speeds of 30 miles per hour.
  7. Female orcas give birth on average every three years after age 13. Some may average giving birth every ten years.
  8. The dorsal fin of the male orca is the tallest of all the whales! It can be up to 6 feet high. Their dorsal fin will not be at full height until 12-20 years.
  9. Female orcas live to be 90 years old, while male orcas live to be about about 50 years.
  10. Orcas are known for excellent eyesight above and below the surface of the water.
  11. Orcas are common to the Arctic and Antarctic waters, but are found in every ocean around the world.
  12. Orcas eat up to 500 pounds of prey (e.g., fish, walruses, seals, sea lions, penguins, squid, sea turtles, sharks, as well as other types of whales) a day. They live and hunt in cooperative and playful pods forming packs – they’ve even picked up the nickname ‘wolves of the sea’.
  13. Orcas do not chew their food. They use their teeth for ripping and tearing prey, but most often swallow their prey whole. Their teeth are up to 3 inches long!
  14. Orcas have a gray area behind their dorsal fin, known as the ‘saddle patch’, that are unique to each whale.
  15. There are only 86 orcas left in the Pacific Northwest’ Puget Sound population. This population is threatened with extinction due to pollution, climate change and food shortages. You can sign a petition with Change.org to help keep orcas on the Endangered Species Act (Well, you can sign until January 27, 2013).

I am sure I missed many interesting details in this “Sink your teeth into this” post. Please feel free to add your favorite below or you can learn more here.

The world’s horseshoe crab research finally finds a home

January 16, 2013 by 1 Comment

This month the Ecological Research & Development Group (ERDG) released a one-stop-shop for research, conservation, and education initiatives on the world’s four species of horseshoe crabs. This was a result of the discussions from the 2011 International Workshop of the Science and Conservation of the Asian Horseshoe Crabs held in Hong Kong.

Be sure to check it out today. There’s lesson plans, peer-reviewed articles, posters, PowerPoint presentations, and more. It’s the intention of the database to serve as a tool to benefit everyone who is in Limulus Love!

I was surprised to learn that the new database includes over 2,000 citations and ERDG is still looking for more materials from people like you and me (Maybe, I’ll submit my cheesy infographic).

Strike a pose with Shark Stanley for shark conservation

January 3, 2013 by Leave a Comment

Surely you’ve taken pictures with Flat Stanley, a tool used to advance children’s literacy – But, did you know that you can now take a shark on your adventures? 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.
Print Shark Stanley and take a picture with him showing your support. Don't forget to tag @SharkDefenders, #SharkStanley, and the country you live (i.e., #USA).

My favorite posts from 2012

December 31, 2012 by 2 Comments

This isn’t the typical list of the most popular Beach Chair Scientist posts throughout the year. Those posts typically include questions typed into a search bar such as ‘Do sharks have bones?’ or ‘How much salt is in the ocean?’. Not surprisingly, my favorite posts aren’t focused on straight up interpretation, but rather have more stewardship and conservation as their subject matter. Here is a list of my favorite posts from 2012 and why I enjoyed writing them.

And here is one of my favorite images posted from this year:

Merry Christmas!

I just want to extend a simple wish for a safe holiday! Here is an image of a driftwood ‘tree’ that my daughter and nephews decorated with clam shells.

“A song, a song, high above the trees,
With a voice as big as the sea,
With a voice as big as the sea,
Said the shepherd boy to the mighty king,
do you know what I know,
In your palace warm, mighty king,
do you know what I know?
A Child, a Child shivers in the cold,
Let us bring Him silver and gold,
Let us bring Him silver and gold,
Said the king to the people everywhere,
listen to what I say,
Pray for peace, people everywhere!“

Lyrics from one of my favorite holidays tunes “Do You Hear What I Hear?”

December 13, 2012 by 1 Comment

With less than two weeks before the big ‘gift-o-rama’ day, it’s time to hunker down and get those gifts in time for wrapping and shipping (after all, shipping ground is a lot less harmful for the environment than air). Here’s a list of gift ideas that will inspire anyone on your list to follow your lead to take an active role in loving and learning about the ocean.

Ho, ho, ho! Look who’s coming to town … it’s the bearded seal!

December 12, 2012 by Leave a Comment

The rather short snout with thick, long, white whiskers gives this true seal it’s appropriate common name. The bearded seal (Erignathus barbatus) can be as long 8 feet and weigh up to 800 pounds. I guess now we know what idiom they use under the sea instead of “the 800 pound gorilla in the room …”. These seals tend not to be seen in packs like their more social counterparts we view along harbors.

Bearded seals spend most of their lives in the Arctic waters, although one was recently found in southeast Florida. They enjoy feasting on arctic cod, shrimp, clams, crabs, and octopus and have been known to live up to 25 years. For more information on the conservation efforts and status of the bearded seal population please check out this page created by the NOAA Fisheries Service Office of Protected Resources.

Jingle shells, jingle shells, jingle all the way

December 5, 2012 by 3 Comments

Oh, you know it’s stuck in your head. If not the Christmas carol, than the image of the beautiful shell that leaves a twinkle in the sand as you walk along the shoreline. Many people assume jingle shells are juvenile oysters because they’re often attached to them. But, jingle shells are their very own species known as Anomia simplex. Here are 10 facts for you to better get to know this treasured beachcomber’s find.

1. Jingle shells have thin, translucent shell halves that look like frosted nail polish.
2. Jingle shells have also been nicknamed “Mermaid’s Toenails”, “Saddle Oyster”, or  “gold shell”.
3. Jingle shells appear all year and are found in shallow waters, beaches, oyster beds, and mollusk shells as far north as the coast of Nova Scotia, and all the way down south to Brazil.
4. The jingle shell is a bivalve mollusk, similar to mussels, oysters, and scallops, which all have two separate shells or “valves”. The upper valve is rounded and movable. The lower valve is typically flat and forms to the object which it is attached. It has a hole in the top where tufts of filament, the animal’s byssal threads, grow out to attach it to another surface (i.e., Jingle shells are epifaunal just like bromeliads).
5. The raw meat of the jingle shell is sharply bitter to the taste.
6. The jingle shell can reach up to 1-3 inches.
7. The lower valve of the jingle shell remains white, while the upper valve ranges from shiny lemon yellow, golden, brownish, silvery black, or pale buff. The shiny iridescence of the jingle shell is retained even after death.
8. Jingle shells take in water and filter nutritious plankton and other food through ciliated gills.
9. Jingle shells were given their common name because of the sound they make when strung together. Beachcombers often use jingle shells to make jewelry or wind chimes. Julia Ellen Rogers noted in her 1931 The Shell Book that “Pretty lampshades are made by piercing the valves of jingle shells near the hinge and stringing them, then attaching the strands so as to fit over the outside of a plain glass or porcelain shade, whose brightness is pleasantly mellowed by the network of shells”.
10. Fishermen have been known to disperse jingle shells over oyster beds in a process known as “shelling” to create a habitat for oysters can settle.
