TL;DR: Genetic studies indicate that migration in squids is extensive but can be blocked by major oceanographic features, and in cuttlefish and octopus migration is more locally restricted than predictions from life history parameters would suggest.

TL;DR: The present paper presents brief reviews on these topics, followed by a discussion of the general challenges that cephalopod research is bound to face in the near future.

TL;DR: An objective method was developed for determining discontinuities in morphological measurements of three species of oceanic squids, whereby the regression model incorporated a fixed breakpoint that was increased in each iteration across the range of dorsal mantle lengths (DMLs).

TL;DR: The pad-shaped club and long neck are proposed as visual markers of the end of the paralarval phase of C. sicula and Brachioteuthis sp.

TL;DR: The external anatomy of individuals at several post-hatching ontogenetic stages of three species of ommastrephid squids was examined and the hypothesis that the tentacles separate gradually then rupture at the “wrist” (presumptive carpus) is argued against the possibility of prey capture by the fused tentacles.
