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.

The answer is appropriate for this time of year … those quarter-sized holes are the home the ghost crabs or fiddler crabs. Ghost crabs emerge to scavenger upon anything they can get including crabs or clams, bugs or insects, plants or dead stuff (detritus). The burrows are personal territories (i.e., not colonies like on Meerkat […]
In the most amateur sense you would call yourself a shell collector…However, considering the fact that you are not just collecting for the sake of collecting (although you may be), but to study the specimens (even if it may be in the most primitive sense), therefore, you can call yourself a conchologist. A person that […]
This is the first post I’ve answered directly from my phone (Please excuse the brevity). Barnacles are crustaceans. Other crustaceans include crabs and lobsters. Barnacles are a type of crustacean that are permanently attached to a solid surface. Also, what is obviously missing is the sensory parts, such as eyes and feelers. Up close, you […]
I came across this image of a dissected sea star and had to share it. It does a great job of identifying intricate details of the sea star physiology that are involved with the locomotion and vascular system of the invertebrate. The vascular system is part of the circulatory system that helps transport nutrients back […]
You must be brave enough to pinch the body of the blue crab from behind and lift it upside down (It hurts a lot if they pinch you!). Male blue crabs have a distinct shape like a pencil – or the Washington Monument – in the center of their bellies. Female blue crabs, on the […]
It’s not too late to find a costume for your little one to show-off a growing love of the ocean for this Halloween! Here are five adorable costumes I found on Etsy that are worth some serious consideration. (The only reason I was looking was because I keep checking to see if anyone has made […]
One idea I had when I started this website almost ten years ago was that I wanted to make science simple and accessible. I hope I have created a place where questions on anything from barnacles to whales can be answered in a knowledgeable no-nonsense or overly jargon tone. My secondary goal has also been […]
In observance of the anniversary of the first transatlantic voyage on May 22, 1933, Congress has set aside this day to recognize those in the maritime industry. The North American Marine Environmental Protection Agency (NAMEPA) and the North American Maritime Ministry Association (NAMMA) are teaming up for their fourth National Maritime Day celebration next week […]
Fish species that frequent the cold temperatures of the Arctic Ocean (e.g., toothfish, cod, ice fish, etc.) have special ‘antifreeze’ proteins within their blood stream that enables them not to freeze in the cold waters of the northern hemisphere. This discovery was made about 50 years ago. Recently, scientists from the Ruhr-University Bochum in Germany […]
Rest assure those crab skeletons are not all dead crabs. They are the molts from the animals. Crabs, lobsters, horseshoe crabs, and many other crustaceans go through a molting phase and the old shell is basically washed up in the wrack line. The wrack line is the deposits from the ocean after the tide has […]
