A small, sessile aquatic animal belonging to the phylum Endoprocta, characterized by a ring of tentacles around both its mouth and anus.
From Greek endo- 'within' + proktos 'anus.' The name refers to the anus being positioned within the tentacle ring, distinguishing them from similar-looking bryozoans.
Endoprocts are among the ocean's tiniest mysteries—barely visible without magnification, they live on rocks and seaweed with their adorable crown of waving tentacles, yet remain virtually unknown outside scientific circles.
