Semelidae

Semelidae is a family of marine bivalve molluscs in the order Adesmacea. These clams are characterized by their equivalve, inequilateral shells. The shells are typically ovate and often possess a posterior gape, which is a common feature in burrowing bivalves. Semelidae clams are found worldwide, inhabiting a variety of marine environments, from intertidal zones to the deep sea. They are deposit feeders, using their siphons to draw in sediment and filter out organic matter. The family includes several genera, such as Semele, Cumingia, and Loxotrymya. Species within Semelidae exhibit diverse life habits, but many are found burrowed in sand or mud. Their ecological role is significant, contributing to nutrient cycling and serving as a food source for other marine organisms.
