Overview

Comprehensive Description

Biology/Natural History: The muscular enlargements at the base of Barentsia entoprocts allow the stalks to bend at that point, and they seem to frequently "flick" themselves by bending at the base. Unlike bryozoans, their tentacles cannot retract back into the calyx. Instead, they fold down horizontally across the center of the calyx like the petals of a flower when it closes.

The zooids of this species are connected by stolons. The stalks are thin and unbranched and have a bendable muscular enlargement at the base but not elsewhere on the stalk.
