Pholad borings
Pholad borings are tubular burrows in firm clay and soft rock that have been created by bivalve molluscs (boring clams) in the family Pholadidae. The common names of clams in this family are "pholads", "piddocks", and "angel wings"; the latter because their shells are white, elongated and tend to be shaped like a wing and have sculpture somewhat reminiscent of a wing.
