Description

<p>Cuspidariidae is a family of bizarre heterodont bivalves with a specialized carnivorous lifestyle. An unusual cuspidariid bivalve was discovered from 2,489 m depth in the Snail hydrothermal vent site, Southern Mariana Trough, and is described herein as Thermomya sulcata n. gen. & n. sp. Although cuspidariids are well-known from the deep sea, until now none were known to inhabit chemosynthetic ecosystems. In fact, this is also the first member of the clade Anomalodesmata found in hydrothermal vent ecosystems.</p>
