This is an angel shark video.
From British daily The Independent:
The great white shark is being hunted to extinction in the Mediterranean, while angel sharks have disappeared altogether from the North Sea according to a report from the UN’s Food and Agriculture Organisation (FAO) meeting in Rome.
Although listed as an endangered species since 1983, the great white is legally protected only in Malta.
The UK government promised to protect angel sharks in 2001 but, six years on, nothing has been done and they are now classified extinct.
