Echinarachnius parma, otherwise known as the common sand dollar is native to the northern hemisphere, specifically the north Pacific and northwest Atlantic, and all along the North American east coast. This sand dollar was found washed up onshore. The common sand dollar typically inhabits isolated sand beds below low tide level down to 1500 m in depth. It is distinguished by its round, flat, and disk-like shape typically 7.6 cm in diameter. Its shell is purplish brown in color and covered with maroon-colored moveable spines. A fun fact about this species is that it has been around since the Pilocene epoch.

Descripción

This was found alive in East Boothbay near Bigelow Labs at 30 feet during a dive.

Northern Cerianthids resemble feather duster worms, but are actually anemones. they are generally white or light brown colored but can be darker reaching even purple colors. The tentacles were about two inches long outside of the tube, though are much larger under the sediment. They can be found from the Arctic down to Cape Cod, preferring colder waters.

The Cerianthids like this one are unique among anemones due to their lacking a pedal disk. Instead of attaching to racks, they make their own protective tube that hides their body burrowed under the sediment. They can retract into the tube when threatened much like feather duster worms.

Descripción

This moon snail was seen in around 20 feet of water in a sandy area off of Canoe Beach in Nahant. This species are found on mud and sand, inter tidally from Gulf of St. Lawrence to North Carolina. The shell is thick and globular, the spire is low, the aperture is large and oval with a whitish interior. The operculum is brown, thin and horny. The umbilicus is open, showing the inside wall of the whorls almost to the apex. The foot is very large and gray. The tentacles are yellow and the color of the shell was gray to brown. A fun fact about the moon snail is that it forms a sand collar by embedding its eggs into the sand mass and uses its mucous to mold the egg ribbon around its shell.
