Hippoporina indica

Hippoporina indica

Hippoporina indica is an encrusting bryozoan native to India and China. It has been introduced to the East and Gulf Coasts of the United States, Belize, Puerto Rico, and the Caribbean and Pacific coasts of Panama, near the Panama Canal. It has been reported on PVC settling plates, fishing rafts, fish cages, buoys, oysters, and barnacle shells. In its native range it is a dominant fouling organism growing on aquaculture equipment and overgrowing other invertebrate species; however, no negative impacts have been reported for H. indica in its introduced range.
