D, the beaks found in sperm whale stomachs vary, but are often large, and we believe sperm whales to be capable of catching the largest Mesos out there, which is why we currently estimate maximum size based on the largest beaks recovered from stomachs.

AC, perhaps you are thinking of the giant squid, Architeuthis dux? Total length for that species is thought to top out around 13m but most of it is arms and tentacles and the whole animal probably maxes out around 300kg. We used to think that the colossal (Mesonychoteuthis hamiltoni) might reach about 10m including tentacles, but I don't think that's true anymore.

Hmm, I suppose that could be a factor, although they eat a fair amount of smaller, agile squids from other families as well. I would think the big squid would be good prey because they'd be the best return on hunting energy investment.
