Marine & Freshwater Environmental Education
Even though they have ten legs – not, eight – we’ve always said horseshoe crabs are members of the arachnid family. It was first theorized by E. Ray Lankester in 1881. But, until recently, it had not been proven in terms of genetics. Scientists at the University of Wisconsin-Madison studied the molecular evolutionary patterns of Limulus polyphemus to confirm Lankester’s theory. So they are still a great addition to your Halloween decoration box.

Ok, maybe not so much in the title. Did you know sharks have roamed the earth for 400 million years and have been instrumental in maintaining healthy ocean ecosystems? They’re amazing creatures and in case you’re actually interested in learning about sharks (instead of becoming frightened by them while watching Shark Week), here are 12 […]
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 […]
Tides. Winds. Waves. You might think of those right away when you ask yourself “Why are beaches so different from one another?” The story of how and why beaches are unique is more than what we witness while lying in a beach chair watching the tide go out hour by hour. The personality of a […]
Bony fish have a swim bladder, a gas filled sac. The swim bladder originates as part of the belly. The swim bladder aids in creating an equilibrium with what is going on inside the fish and the surrounding water. Some fish have a bladder that is part of the respiratory system, called an air bladder. […]
Ahh, you see the polar ice sheets and glaciers are melting, but the water still needs to go somewhere – the ocean. The water then rises transforming geography, manipulates the balance of salt in estuaries and creates higher flooding intensity. Basically, rising sea levels affects coastal areas the most drastically. But, don’t dismay! The EPA, […]
Well, it is important to mention that not all mussels are found on pilings. Mussels attach themselves to any type of hard substrate in the intertidal regions, including pilings. On pilings the top most mussels indicate the high tide line. To go off on a random tangent, here is a yummy mussel recipe: http://allrecipes.com/HowTo/Cooking-Mussels/Detail.aspx Do […]
In honor of Shark Week on the Discovery Channel I decided to post a different shark fact each week. Today…What is the fastest shark species? The mako shark is the fastest shark. It can get up to 20 miles per hour (or faster when being chased by an enemy). The mako shark can naturally move […]
I love the game Scattegories so I am going to be drawn to learning new words that will help me gain more points. The Baffin Bay separates Greenland from Canada and is connected to the Atlantic Ocean by the Davis Strait. You won’t be finding any vacation homes along the shores of the Baffin Bay […]
Environmental News Network sent a news release out today about a new report that states how Orca orca may die off if the numbers of king salmon continue to drop. The research was published in the Royal Society Biology Letters. The leading cause of the death of the killer whales is actually “nutritional stress” from […]
