Etymology The specific epithet carinhosa, feminine of the Portuguese adjective carinhoso and meaning 'gentle, 'kind', or 'tender', refers to the care of the offspring showed by females of the species. [details]
Habitat Polydora carinhosa bores in shells of the oysters Crassostrea rhizophorae and C. gigas, at shallow water. [details]
Reproduction Gonochoristic. Females deposit eggs into capsules which are joined to each other in a string. Each egg capsule is attached by two thin stalks to the inner wall of the burrow. Larvae develop inside the capsules until about the 14-chaetiger stage. The kind of lecithotrophy (endo- or exolecithotrophy) in Polydora carinhosa is unknown since only two broods with 10- and 13–14-chaetiger larvae were found. Holotype male, with sperm first present in chaetiger 27. [details]
Type locality West Atlantic Ocean, Brazil, Paraná, Paranaguá Bay (25º28'S, 48º27'W), 2 m, from shells of the oyster Crassostrea rhizophorae. [details]
