Comment from Richard Willan on photo #2520
A very large adult individual. It has shed (autotomised) most of the cerata which is why you can see more of the back than usual. These cerata are just starting to regrow, and they appear as small brown pointed ‘tentacles’.Comment from Richard Willan on photo #2096
This seems to be an exceptionally large individual because of all the very numerous cerata.Locality:
