The subfamily Bathymodiolinae is found in deep-sea habitats.

This is in sharp contrast with the typical deep-sea habitat, where deposit-feeding animals rely on food they get off the ground.

Beaked whales are one of the least known groups of mammals because of their deep-sea habitat, mysterious habits, and apparent low abundance.

Members of this genus are characterized by their deep-sea habitat, clear bodies, and ability to engorge themselves with water to become larger when threatened.

It is found in rocky deep-sea habitats around the Chatham Islands, New Zealand.

The giant squid, Architeuthis, has never been seen alive in its natural, deep-sea habitat.

Bentheuphausia amblyops, a bathypelagic species, has a cosmopolitan distribution within its deep-sea habitat.

They live almost exclusively in deep-sea habitats, although a few live in shallow waters in the Antarctic.

Recent scientific reports have shown that some deep-sea habitats are in need of protection against mechanical erosion caused by fishing gear.

We must investigate what other deep-sea habitats need to be protected so that we might obtain a complete list of these.
