Life history
- has two larval stages, a trochophore and a veliger-
- both are planktonic and can migrate in the water column-
- veliger larvae settle (called “spatfall” and grow shells, feet, etc..
Adaptations
- they strain small plankton using cillia to carry plankton-laden water over the gills
- usually rest on the benthos, but can swim by “jet propulsion”, caused by opening and shutting of their shell
