This rare anglerfish has been captured on video for the first time by a team of US scientists, using a remote-operating vehicle (ROV).
Chaunacops coloratus was described in 1899 from a dead specimen, but up until now, has never been seen alive.
The footage (see below) was taken by a team from Monterey Bay Aquarium Research Institute (MBARI) at depths of 7,800-10,000' off the coast of California.
The video also shows the difference in coloration between blue-grey juveniles and the bright red adults.
