Can anyone tell me what we are looking at here (further stomach contents from blue shark off northeastern New Zealand). From the same area we have now recorded Architeuthis and Taningia from the sharks stomachs. It is rather odd, rather interesting and rather submature (judging on the extent of darkening of the beaks wings (Fig 2)). It gets a fair bit larger than this! The detached arm (Fig 3) has grossly enlarged suckers. Arms 1, 2 and 4, and the tentacle stump on the animal's right hand side are attached to the remains of the head; each arm has moderately enlarged suckers along the mid-portion, but nothing quite so remarkable as that on the detached arm; the tentacle stump is devoid of systematic characters. The only arm that is incomplete is the 3rd right; those on the left hand side are detached/missing. I believe this arm to be that of either the third left or right of this specimen, so the suckers are enlarged on each arm, but demonstrably so on the third arms. The specimen is in pretty poor shape, and there are no traces of either hooks or sucker rings (these have digested away). It is probably a species of Megalocranchia, but it is larger than anything with which I am familiar from local waters (adults are extremely rare, probably attaining mantle lengths of ~ 0.9 metres); it is a cranchiid squid, like the colossal squid (Mesonychoteuthis hamiltoni). I need to check beak morphology in more intact, smaller specimens to be sure of the identification, but perhaps someone has some idea already and would like to comment.
