The snailfish was found 8,336 meters deep. This discovery set a new depth record for fish in April 2023.

Unique Species Identified

The DSSV Pressure Drop’s camera system documented this unique fish. Bait was used to lure the fish into view.

Adaptations to Survive

This snailfish thrives under extreme pressure. It lives in an environment with pressure 800 times that of the surface. Adapting to such depths requires special traits. The snailfish has evolved to handle these harsh conditions.

Baiting the Fish
