Further remains of an unusual deep-sea creature called a seven-arm octopus have been found on an Aberdeenshire beach.

Arms with rows of suckers were initially discovered by a member of the public at Forvie National Nature Reserve at Collieston, near Ellon, on 30 November.

Some detective work by conservationists led to the animal being identified as a septopus, a species with eight arms like other octopus - but in males one of the arms is also a reproductive organ that they attach to females when mating.
