Types of Habitat

Pacific Toothed Oyster, Isognomon isognomon has an impressive ability to persist in a wide range of habitat. It is an epifaunal, benthic feeding species. With the exception of its dispersed lava, the adult form has no locomotive abilities. It can be found in water depths ranging from 0 to 3km depth of water. Its versatility to persist in different regions can also be expressed through its ability to persist in regions of subtropics, temperate and tropical conditions. Most of these bivalves can be found in marine waters but some were also found in estuarine and brackish environments (Yonge, 1968). The only definite habituation of these pteroids is that they are all attached to rocky substrates and in crevices. They are also relatively cryptic but have a high tendency to occur only on the underside of rocks and crevices (Tsubaki et al, 2010).
