Thracia pubescens (Pulteney 1799)

Femorale cc-by-nc

Thracia pubescens (Downy Thracia Clam) is a species of mussels in the family Thraciidae. They are downward conveyors. Individuals can grow to 90 mm. They have sexual reproduction. They are facultatively mobile animals.

URI: http://polytraits.lifewatchgreece.eu/terms/RW_DC
Definition: Downward conveyors exhibit a feeding strategy opposite to that of upward conveyors. Vertically oriented head-up feeders actively select and ingest particles at the surface and egest these non-locally as faeces in deeper sediment strata

URI: http://purl.obolibrary.org/obo/GO_0019953
Definition: Capable of creating a new organism by combining the genetic material of two gametes, which may come from two parent organisms or from a single organism, in the case of self-fertilizing hermaphrodites.
