How to Distinguish from Similar Species: Other local entoproct species are not connected by stolons, or thick or have branching stalks, or have several bendable enlargements along the stalk.
The muscular enlargements at the base of Barentsia entoprocts allow the
stalks to bend at that point, and they seem to frequently "flick"
by bending at the base. Unlike bryozoans, their tentacles
retract back into the calyx. Instead, they fold down
across the center of the calyx like the petals of a flower when it
