Olindias is a genus of hydrozoans in the family Olindiidae.

Characteristics

Members of the genus Olindias have a dome-shaped bell, four radial canals and many centripetal canals. The gonads are beside the radial canals and have characteristic papilliform processes. There are a few primary tentacles growing part way down the bell with adhesive suckers and cnidocytes in bands. There are a pair of statocysts adjoining the base of each primary tentacle. There are a much larger number of short marginal tentacles with rings of cnidocytes for immobilising prey. Between these tentacles there are a number of club-shaped processes which may develop into tentacles.[2]
