Piddocks
Piddocks are a type of marine mollusk belonging to the family Pholadidae. These bivalve mollusks are known for their ability to bore into and inhabit various types of hard substrates such as rocks, clay, and wood. Piddocks have a characteristic cylindrical shell with a small opening at one end through which they extend their siphons to feed and respire. These organisms play a crucial role in marine ecosystems by facilitating the breakdown of hard substrates and creating habitats for other species.
