Since taking up snorkeling last year, I’ve seen a few things in and out of the water that I’m having trouble identifying. Any ideas? All of these are found in the waters of New England, more specifically the Southern Cape and islands.
On the shore, the sand is littered with hundreds of thousands, if not millions, of shells. These are usually white (though maybe sun-bleached) univalves, about an inch long and 3/4 inch wide. They are slightly teardrop shaped, but with a slight curve.There’s not much of a chamber, just a little bit of wall near the smaller end. While in the water they are sometimes stacked one upon the other, sometimes as many as 10 high. I sometimes see them inhabited by hermit crabs, but they don’t seem to be the typical hermit crab shells.
Crabs–they are around the size of blue crabs, but their shells look like fuzzy black rocks. They have long slender black legs, making them look a little like tarantulas. (Or really large daddy long legs.) Their claws are pretty small, and they don’t use them to threaten intruders like a blue crab might.
Something that looks like a bag of crap. They look like either bags or long sausage casings resting on the sea floor. (Shallow water.) They are a translucent dark reddish brown. They look like they’d disintegrate on contact.
What might be sand, piled up into what looks like a pile of string. Around an inch or two tall, slightly wider. Almost looks like a small sea critter took one mighty dump, all in one place.
