The first deep-sea ctenostome bryozoan from the Indian Ocean: Aethozoon flavum sp. nov.

Aethozoid ctenostome bryozoans are an unusual, small group of solitary ctenostome bryozoans, occurring almost exclusively in deep-sea habitats. Currently, there are only five species belonging to four, still insufficiently known genera, which have been reported from the Atlantic and Pacific Oceans....
