Mollusks

Argonauta argo, the Greater Argonaut, a cephalopod

The Mollusks are one of the most successful phyla with over 100 000 living species and are found worldwide. Search Ocean Biogeographic Information System (OBIS) for databases of mollusk distribution. They have a head-foot complex, a mantle that secretes a calcium carbonate shell and a gill, suspended in the mantle cavity, which is used for respiration and commonly for suspension feeding. There are several kinds of mollusks:

Gastropoda (snails),
Bivalvia (clams, oysters and mussels),
Cephalopoda (squid and octopus),
Polyplacophora (chitons) and
Scaphopoda (tusk shells).

Mollusks have an important role to play in the ecosystem, varying from the herbivorous chitons feeding on microalgae and seaweeds attached to rocks; bivalves filtering phytoplankton and organic matter in sediment; the shipworm Teredo which bores into wood; to the specialist carnivores like octopuses feeding on individual crab species. Many species are important for aquaculture.
Based on Levinton, J S, “Marine Biology. Function, Biodiversity, Ecology” Oxford University Press.

Census of Marine Life, now concluded, had a number of projects that included mollusks:

Ocean Biogeographic Information System (OBIS). Search for data on the distribution of mollusks. Go to the bottom of the screen, in the Taxonomic Category drop-down menu, select Molluscs and hit Search,

CephBase is a database-driven web site on all living cephalopods (octopus, squid, cuttlefish and nautilus),

History of Marine Animal Populations (HMAP),

Future of Marine Animal Populations (FMAP), and

technology to study marine life.
