Catenicella

Catenicella is a genus of marine bryozoans belonging to the family Catenicellidae. Bryozoans are colonial animals that live in aquatic environments, and Catenicella is no exception. Members of this genus are found in oceans around the world, with a particularly high diversity in the Arctic and Antarctic regions.

== Description == Catenicella colonies are made up of tiny, interconnected zooids, each with a circular or oval-shaped operculum (a protective lid that can be closed to protect the animal inside). The colonies form thin sheets or branching structures that attach to hard substrates such as rocks or shells. The colonies themselves can range in color from white to yellow, pink, or brown.
