Crispiae

Crispiae refers to a genus of marine bivalve mollusks belonging to the family Veneridae. These clams are characterized by their relatively small, equivalve, and inequilateral shells. The external surface of the shell typically exhibits concentric growth lines and may have radial ribbing, giving them a somewhat ribbed or textured appearance. The shape of the shell can vary but is often ovate or rounded.

Species within the Crispiae genus are found in marine environments, inhabiting sandy or muddy substrates in shallow to moderately deep waters. They are filter feeders, drawing water into their shells to extract microscopic food particles. Like other venerid clams, Crispiae play a role in their benthic ecosystems by processing sediment and serving as a food source for various predators. The exact distribution and abundance of different Crispiae species can vary geographically. Further research into specific species is often required to understand their ecological niche and life history in detail.
