Limpets are small, flattened snails with a conical shell that live on rocks in the intertidal zone. They trap water beneath their shell and use it to survive from high tide to low tide.

There are two types of whales: baleen and toothed. Baleen whales are the magical creatures that create “songs” under water. The series of high pitched squeals, shrieks, groan and moans can last anywhere up to twenty minutes and be as low as 20 Hz and high as 10,000 Hz. Male whales (bulls) tend to use […]
Last year I was pretty proud of my sea & sky pumpkin featuring constellations, a sunset, fish, a seahorse, and horseshoe crabs and I’m at a loss on what to do this year. I started a template for a much larger horseshoe crab so I thought I would share it with you (HSC_template). I actually […]
Oysters are another bivalve animal. In the case of all bivalves, the part of the animal that lines the shell is known as the nacre and the part of the animal that make up the outer shell is known as the mantle. A pearl is created rather by accident when something foreign gets stuck inside […]
The strand of half dollar sized pods is an egg case. Actually each pod has about twenty tiny animals in each pod. The tiny animal that will grow from this egg case is the knobbed whelk. This is basically a northeast version of a conch (pronounced conk). If you hold the tiny discs up to […]
They hatch from the egg looking exactly like typical fish, swimming in the upper waters. After two weeks the bridge of the fish’s nose fades away and then one of the eyes, depending on the species, shifts to one side. The process of becoming a complete “flat” fish takes a bit of time, but, once […]

12% of land is protected, while only 2% of the sea is protected. That’s not proportional when you think that the ocean takes up over 70% of our planet. Please watch this incredibly creative, punchy, entertaining, and most importantly, inspiring video from One World One Ocean. I was inspired enough to want to share it […]
Since a 2008 resolution by the United Nations, June 8 has been designated as the universal “World Oceans Day”. Each year, non-profit The Ocean Project pulls together a great list of events from around the world celebrating World Oceans Day. The theme for 2010 is “World of Life”. “Wear Blue, Tell Two” In 2009 the […]
First, sea stars grip their prey (e.g., bivalves, such as clams and oysters) with their suction feet and pry them apart to eat the muscle inside the shells. Then, once the bivalve’s shell is open, the stomach of the sea star emerges from the middle of the underside of its star-shaped body to absorb the […]
Thank you to the Northeast Office of the US Fish and Wildlife Service for posting this graphic on their Twitter feed! With the mention of horseshoe crabs, how could I not repost this!?! Did you know that shorebird hunting in the Caribbean and South America may contribute to the red knot’s decline along the Atlantic […]
