Colonies of Amathia vidovici are like miniature trees and consist of a branching mass of individual zooids connected to each other by stolons.

[2] Amathia vidovici feeds on bacteria, diatoms and phytoplankton by sifting particles from the surrounding water with its lophophore.

The embryology of Amathia vidovici has not been studied[2] but most bryozoans produce large, yolky eggs which are retained in the body cavity.

[3] Amathia vidovici is typically found growing on rocks, seagrass, seaweed, mangrove roots, oysters, mussels, man-made structures and debris.

[4] The colonies provide shelter for juvenile fish and for the copepods, amphipods, polychaete worms and other small invertebrates on which they feed.
