First filming of deep sea fish
A rare species of anglerfish has been filmed for the first time by US scientists.
The deep-dwelling fish, Chaunacops coloratus, was first described in 1899 from a dead specimen but has not previously been seen alive.
In this clip, filmed using a remote-operated vehicle, you can see the fish swimming and lying on the sea bed.
The discovery was made by the team from the Monterey Bay Aquarium Research Institute (MBARI), California, US.
