Crepidula
Encyclopedia
Crepidula, common name
the "slipper limpets" or "slipper shells", is a genus
of sea snail
s, marine
gastropod mollusks in the family Calyptraeidae
, the slipper snails and cup-and-saucer snails.
The genus Crepidula is probably the best studied group within the calyptraeids. A variety of species are commonly used in developmental, ecological, and behavioral research. They have been the major focus of research on protandrous sex-change in marine invertebrates and have been used to demonstrate that sex change is environmentally mediated (the timing of sex change depends on association with other individual snails). Crepidula fornicata and Crepidula onyx
are well-studied examples of invasive, exotic species in marine habitats.
synonyms:
to capture microalgae from suspension, but there is some evidence that small juveniles can also use the radula
to scrape algae from the substrate

Ecology
Like all calyptraeids, slipper snails are sedentary filter-feeders. Adults use their large gillGill
A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water, afterward excreting carbon dioxide. The gills of some species such as hermit crabs have adapted to allow respiration on land provided they are kept moist...

Substrate (biology)
In biology a substrate is the surface a plant or animal lives upon and grows on. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock can be substrate for another animal that lives on top of the algae. See also substrate .-External...
