I have two questions about the two more agressive squids. First, does the Humbolt Squid (D. gigas) lack tentacles? I've recently noticed that I've seen the eight arms on the thing, but never any tentacles. Second, how does the swivel motion on the Colossal Squid's (M. hamiltoni) arm-mounted claws work? In last year's newscast about a Mesonychoteuthis carcass, I saw Steve (or Kat) stick a finger towards one of the claws, and push it in a circular direction so that it made it seem that the squid can swivel it's claws, I'd like to know how that's structured and how that swiveling works. I've been racking my brain and searching the 'net, and haven't found a thing that helps answer these two questions.
