Five surprising facts about sharks

Why are we so enamored with sharks? Why are we glued to the television in the summer during the last hours of daylight to watch fish on TV rather than playing a final game of wiffle ball or pick-up basketball? Does it have something to do with the fact that there are over 400 different types of sharks and always something new to learn? Anyway you slice it, these cartilaginous fish are pretty cool. Here are five surprising facts about sharks that will certainly get you excited to learn more and watch this year’s (hopefully) new and improved Shark Week. What is your favorite fact about sharks?

Nine signs of summer you’re still a kid at heart

I just got back from a little family vacation where we went to the luxurious place I called home for many years (i.e., “the Jersey shore”). Don’t get me wrong, being with the kids any day takes my breath away (from both ends of the spectrum, let’s be honest). But, spending time along the Atlantic coast on the barrier island where I grew up (as a local, not just “for the summers”) is such a different experience with the kids (four and one) is a remarkable opportunity to really settle and enjoy each moment through their eyes. Here are some fun ways that not only I, but the older family members around me, came to enjoy living like a kid again. Please feel free to comment and share what makes you feel like a kid again too.

Those huge platforms along the causeways are there for a very important reason. Osprey build their nests on them. They’ll also build their nests on any open platform free from predators and near shallow water. But, the man-made platforms have really help to bring back populations of osprey after their sharp decline in numbers due to DDT.  Each year the huge raptors, also known as “fish hawks” because 99.9% of their diet is fish, wait until after the water thaws to build a nest. Since the winter was so long this year along the Mid-Atlantic many of the birds just made their nests in March/April. With an incubation period of just over a month and the young needing just about two months before they take off from the nest it was a perfect time to follow along with Greg Kearns of Patuxent River Park in Upper Marlboro, MD, as he banded juvenile osprey (don’t worry, he has a permit for this kind of thing).

Osprey are banded at a young age to help determine their migration patterns, life expectancy, as well as reasons for mortality. The band that is placed on the young is very light weight and has not hindered their ability to catch food. I am incredibly grateful for his time and dedication to his efforts in conservation and education. Thank you for your enthusiasm and sharing your knowledge with the Mid-Atlantic Marine Education Association late last month. Here are some more interesting facts learned along the way:

  • As with all birds of prey these birds have very sharp talons. But, the osprey have a reverse talon making it easy for them to grasp their prey with two toes in the front and two from behind.
  • The male usually scopes out the spot for the nest to be built several days before the arrival of the female.
  • Osprey are asynchronous incubators and do not hatch all at once. The female typically lay four eggs but usually one two survive. While they do share food distributed by their mother the oldest one dominates.
  • The hunts for food for the mother and young and before he returns to the nest with food he’ll eat about one-third of the fish. Hunting for fish does burn a lot of calories after all. The mother and young will eat the rest of the fish, but seem to not favor the gut of the fish. The adults generally need about 300 grams of fish per day.
  • There is a 40-50% chance of survival for the young. The average age of an osprey is 8-10 years old. The oldest tracked osprey was found to be 33 years old.
  • Their nests are made of sticks from the surrounding marsh plants, as well as animal hide or even litter such as plastic bags.
  • Young osprey have orange eyes that turn brown as they get older.

If you live near shallow water and want to build a platform there are several plans available here: http://www.osprey-watch.org/learn-about-osprey/build-an-osprey-nest/.

Are we one step closer to an invisibility cloak?

Researchers at the University of Bristol have demonstrated how to create artificial skin that can mimic the squid. The squid, as well as other cephalopods like the octopus and cuttlefish, can blend into their surroundings to hide from predators or sneak up on prey.  The squid’s “Passing Cloud” camouflage technique (i.e.,  bands of color spread as waves across the skin) was simulated in the experiment. According to the researchers the implications are more than just avoiding your landlord, they noted that “It could also be used for signaling purposes, for example search and rescue operations when people who are in danger need to stand out”. More patterns are being studied in the future as well.

Maryland moves closer to banning microbeads

Reported on the Baltimore Sun’s B’More Green  blog, “Consumer products such as toothpaste and cosmetic scrubs containing tiny plastic “microbeads” could be banned from store shelves in Maryland after 2018 under a bill unanimously approved Thursday by the state Senate”. These means that if the bill passes the House, “Maryland will be the second state after Illinois to order a phase-out of the manufacture or sale of consumer products containing the beads”.

What is a microbead? It’s a tiny particle of plastic that never break down. What’s incredibly harmful is that they are being drained into local streams, creeks, rivers, lakes, and ocean and affecting our waterways. There are over 50 products on the shelves in the US that contain harmful microbeads! Find a list of products sold in the United States that contain microbeads (i.e., polythene) here.

Here is some alarming information on the microbeads, marine debris, and our ocean trash in general.

  1. A single tube of facial cleanser can contain over 3000,000 microbeads.
  2. More than 450,000 microbeads per square kilometer were found in some parts of Lake Erie.
  3. In the ocean there are approximately 5.25 trillion plastic particles.
  4. For every foot of coastline there is approximately five grocery bags filled with plastic, according to estimates in 2010.
  5. Six continents have microfibers washing up on their shores.
  6. Shores near sewage treatment plants have the highest concentration of microfibers washing up.
  7. Nearly 275 million tons of plastic waste was generated by coastal countries in 2010 — and that 4.8 to 12.7 million tons of that plastic made its way to the oceans.
  8. Each year, 8.8 million tons of plastic goes into the oceans.
  9. The estimate for 2015 is 9.1 million metric tons.
  10. On average, Americans use 220 pounds of plastic per year.
  11. 17% of all marine animals impacted by manmade debris are threatened or near threatened.
  12. Trash will likely increase tenfold over the next decade.

Gifts for the ocean lover: For kids of all ages edition

Still looking for that perfect gift for a certain little one? I have to admit I am the aunt that likes to wrap up books (yes, and usually one of these ocean-themed children’s books). However, in the spirit of the giving during the holiday season, and in watching little eyes twinkle, it’s fun to also wrap a little something extra. Here are five gift ideas for inspiring a love of the ocean in the next generation:

What you need to know about World Shorebirds Day: Saturday, September 6th

world-shorebirds-day1000My husband isn’t happy about this … But, recently, I have found a new love of birds. It’s because we live in the woods and not near the ocean, so those flighted friends have stolen my heart just like fish did back some many years ago. My husband thinks it is hysterical since we grew up in Cape May County, NJ and birders are synonymous with “tourists”, a group to which locals have a love/hate relationship. But, I don’t care … I can hardly contain my excitement for this Saturday – during World Shorebirds Day!

The celebration was proposed and organized by György Szimuly, a well-known bird conservationist based in Milton Keynes, England. Szimuly set out to promote and celebrate shorebirds.

Find out the differences between a seabirds, shorebirds, wading birds here.

“The idea to hold a World Shorebirds Day was inspired by the ongoing conservation issues we have been facing,” Szimuly said. “I think that setting a commemorative day for shorebirds will give conservation bodies and individuals another chance to educate.” He continues that “This is not particularly a citizen science program, but rather an effort to raise awareness for the importance of regular bird monitoring as the core element of bird protection and habitat conservation.”

“I think the global shorebird counts are a good get-together event,” Szimuly said. “I asked birdwatchers to book their site now, where they can go counting shorebirds on the 6th and 7th of September.” There are hundreds of sites and counters already registered for the World Shorebirds Day. The ‘booked’ sites can be seen on the event’s Google Map. https://mapsengine.google.com/map/edit?mid=z3yRwAVo2mAw.k42bDqIRe7a4.

Saltwater vs. Freshwater: Why droughts are a real problem

Earth’s surface is about 70% water. But, only 1% f that is freshwater that is easily accessible (found in lakes, rivers, streams, and ponds). Thanks to McGraw Hill for pulling together this infographic illustrating the amount of water of the surface of the Earth that humans can actually use … just a drop in the bucket really. Consider this reality when thinking about what’s going on over in California this summer with “its third-worst drought in 106 year“.

What’s it like to be a Maine lobsterman?

Are your kids interested in a career on the water? Sounds like a great time to check out this video and go out lobster fishing with the award winning Aqua Kids! They’ll learn from teen lobster fishermen in Maine some of the challenges of the job (e.g., timing how long their nets are in the water, regulating the size of “catchable” lobsters). But, most impressively what is on the young lobstermen’s mind is how to make sure their practices are sustainable.

Aqua Kids motivates today’s youth to take an active role in protecting and preserving our marine environments.
