Ponderous Arks [Cucullaeidae]

Description

Cucullaeidae, or Ponderous Arks, represents a family of deep-sea bivalves with a unique, heavily calcified shell structure. These arks have a globular to elongated shape, with a thick outer layer that provides protection in the deep-sea environment where they reside. Ponderous Arks are adapted to life in cold, high-pressure depths, and their distribution is often linked to cold seep communities or areas with organic-rich sediments. They are detritivores, feeding on organic particles they extract from the sediment.
