Unlike all other Rhabdopleura species, the zooids have black elongated arms with no tentacles.[3]
Distribution
Rhabdopleura compacta occurs in Atlantic waters. It has been found in the English Channel and the Gulf of Mexico.[3]
Reproduction and life cycle
The reproduction and life cycle of Rhabdopleura compacta has been studied by Stebbing (1970) and Dilly (1973).[4][5]
