Mussels

Mussels

Mussels are found everywhere, attached to any solid substrate. Mussels are to the sea what grass is to suburbia. Mussels lack the muscular foot of clams or the large hinge muscle of scallops. Instead, they have a "beard" of tough fibers near the hinge with which they attach themselves.

The Blue Mussel Mytilus edulis, to 4" is the edible mussel. The similar Horse Mussel Modiolus modiolus grows to 6", and is considered inedible. Both types are found from the intertidal zone down to the depths. See entry on barnacles.

The other common type of mussel in our area is the Ribbed Mussel Modiolus demisus, to 4". The Ribbed Mussel is roughly the same shape as the Blue Mussel, but has a ribbed shell instead of smooth. It is usually found in brackish water, in bays, estuaries, and marinas, and is inedible. Freshwater Zebra Mussels are more closely related to clams.


Blood Worm

Glycera spp
Nereis spp.(shown)

Size: to 15", generally much smaller

Worms like this can be found anywhere from tidal flats to deep depths, burrowed in the sediment or hiding in crevices.

These segmented worms have four sharp teeth and can give you a good bite if you're not careful. They can also swim, although not very well. The "legs" are called parapodia and are actually gills. The best place to see a blood worm is at the bait shop. Also known as Clam Worms.
