The dance of the goblets. A glimpse on the life of an Entoprocta

Tiny entoprocts of the genus Barentsia (Phylum Entoprocta, Family Barentsiidae) are found growing on seaweeds or other invertebrates. Inconspicuous due to their small size and cryptic habit, they stand out when well illuminated and seen through the low power microscope. Looking at these entoprocts for the first time, you can misidentify them as a species of hydroid or bryozoan, but their typical nodding motion leaves no doubt which phylum they belong to. Barentsia is colonial with a branching stolon attached to the substrate. Each zooid comprises a calyx, with a crown of ciliary tentacles, that is on top of a cylindrical stalk connected to the creeping stolon. projection. In all entoproct species. Embryos are brooded in the upper part of the calyx, the atrial cavity, and released as larvae to the water column.
