Verticordiidae

Verticordiidae is a family of benthic marine bivalves in the superorder Anomalodesmata. These clams range from 2 - 200 millimeters in length and are mainly found in coastal waters surrounding Australia and the Americas, though a few species within this family such as Haliris mediopacifica are found in the middle of the ocean. Verticordiidae is known for being a family of septibranchs, or predatory bivalves, rather than filter feeders. Clams dig vertical burrows in substrate and use papillae around the edges of their inhalant siphons to detect microscopic prey. Some clams in this family, specifically in the genus Trigonulina, have distinct extended circular formations on their shells.
