Freshwater Mussel Genera of the World - English
URL: http://www.inhs.uiuc.edu/~ksc/MusselGenera.html

The objective of this page is to illustrate (with photographs) all of the "genera" of freshwater mussels (Unionoida) in the world. The genera included are largely those recognized by Haas (1969) with the exception of the North American fauna, which follow Turgeon, et al. (1998).

Sydney rock oyster (Saccostrea commercialis) - English
URL: http://www.ozemail.com.au/~dkgsoft/oyster/oysintro.html

The Sydney rock oyster (sometimes called the NSW rock oyster) has been farmed in southern Queensland and New South Wales since around the 1870s. A species like the Sydney rock oyster has been farmed in Western Australia since the early 1980s. In 1989-90 about 72% of edible oysters produced in Australia were Sydney rock oysters, 27% were Pacific oysters, and the remaining 1% were other varieties such as the native flat oyster, the milky oyster and the blacklip oyster. Oyster farming has evolved from a cottage industry to a commercial enterprise, the largest and most valuable segment of the NSW Fisheries Industry, worth about A$30,000,000 in 1990-91.

Listing of families of molluscs currently represented in the PPP database (largely Neogene of Caribbean Panama). Classification derived from Haszprunar, 1988; Ponder & Warén, 1988; Vaught, 1989; Bieler, 1992; Tracey et. al., 1993 (gastropods); Scarabino, 1995 (scaphopods) and Cardter, 1990; Skelton & Benton, 1993 (bivalves) and subsequent revisions. Chitons and nautilids are represented by very few specimens and taxa, and are not included here.

Class Bivalvia - English
URL: http://www.sidwell.edu/us/science/vlb5/Labs/Classification_Lab/Eukarya/Animalia/

Class Bivalvia (a.k.a. class Pelecypoda) includes all of the bivalves. These are marine animals with a hinged shell divided into two halves. The hinge is head together by a ligament and one or two adductor muscles. Most live in sand or mud, and use their foot for digging and anchoring to surfaces. These bivalves use the hinges to take in food, and are also able to jet some distance away by closing the hinged shell and squirting the water taken in out of the mantle cavity. Bivalves lack a head and have a spacious mantle cavity as well. Some examples include clams, oysters, scallops, and mussels.
