Atlantic Deep-sea Scallop (Placopecten magellanicus)

Sometimes known as the “giant scallop”, P. magellanicus is a species of scallop (Pectinidae) which is native to the western Atlantic, where it occurs from the Gulf of St. Lawrence south to Cape Hatteras. Like most bivalves, Placopecten magellanicus is a suspension feeder, filtering the water around it for nutrients. However, like other scallops P. magellanicus possesses the ability to freely swim for short distances by moving water through its valves quickly.

Cockscomb Oyster (Lopha cristagallii)

…is a species of true oyster (Ostreidae) which is widespread in the Indo-West Pacific, where it occurs from East Africa (including the Red Sea and the  Persian Gulf) to Micronesia; north to Japan and south to Papua New Guinea. Cockscomb oysters typically occur in coral reefs in shallow subtidal waters at depths of 5 to 30 m. Like other bivalves cockscomb oysters are suspension feeders.

Giant Lion’s Paw (Nodipecten subnodosus)

…a species of scallop (Pectinidae) that is native to the Pacific and Gulf of California coasts of the Baja California Peninsula. It also occurs into mexico proper southward to the western coast of Peru. Like most bivalves, the giant lion’s paw is a suspension feeder, extracting nutrients from the water around it. Like other scallop species, when threatened the giant lion’s paw can swim short distances by moving water through its mantle and valves.

“King Scallop” (Pecten maximus)

Also known as the “great scallop”, the king scallop is a species of scallop (Pectinidae) which occurs in waters off of northern Europe, from Portugal to Norway, including the British Isles and Iceland. Like most bivalves Pecten maximus is a suspension feeder, filtering the water around it for nutrients. Like other members of the family Pectinidae, when threatened P. maximus can swim short distances by moving water through its valves.

Common Jingle (Anomia simplex)

…a species of Anomiid bivalve mollusc that can be found along the Atlantic coast of North America, ranging from Nova Scotia to the West Indies. Common jingle shells are common on beaches and are revered among shell collectors. Living Anomia simplex can be commonly encountered in the intertidal zone where they can be found attached to rocks and shells via the use of their byssal threads.

“Kelp Scallop” (Leptopecten latiauratus)

Also known as the wide-eared scallop or kelp-weed scallop, the kelp scallop is a species of scallop (Pectinidae) which occurs from Point Retes, California south to Baja California and the Gulf of California, Mexico. Kelp scallops typically inhabit the low intertidal zone where they will attach to kelp, hard objects and even other invertebrates using their byssal threads.

Ribbed Saddle-oyster (Pododesmus patelliformis)

…a species of Saddle Oyster (Anomiidae) that occurs on the norhtwest fringes of Europe extending from Norway to the Mediterranean Sea. Ribbed saddle-oysters typically occur in the intertidal zone, to depths of 200 ft. They are often found attached to coarse sand, grave, and rocks via thier byssal threads.
