An incredibly rare emperor penguin which is almost completely covered in feathers has been spotted among a colony of others in the Antarctic.
Footage shows the bird standing among hundreds of other emperors with distinctive black backs and heads, white underbellies and yellow patches on their necks.
Unlike its counterparts, the rare specimen has not got a white underbelly - the result of a rare genetic mutation called melanism.
The clip was caught by BBC'S wildlife programme Dynasties, who say that this could be the first time anyone has captured an all black emperor penguin on film.
The all-black emperor 'looked healthy' and in search of a mate with the other penguins which are huddling together for warmth.

All mature emperor penguins have a dark grey back, a pure white belly and and jet-black head, tail and top side of their flippers.
They have a coloured yellow ring covering
