A Russian trawlerman named Roman Fedortsov has been sharing images of some of the fascinating, peculiar and occasionally nightmarish creatures from the depths that have been turning up in his fishing nets.

Fedortsov's trawler operates out of the port city of Murmansk in north west Russia, and he told the Moscow Times he's surprised by a number of the creatures he discovers that he struggles to identify.

He's been posting photos of the catches to Twitter and Instagram - take a look at the incredible photos below, and for more visit his profiles on social media.
