Sperm Whales go down over a mile looking for giant Squid. Must build up some pressure.

That's pretty interesting fact. (seriously) Any web sites with more info on deep diving whales and what they eat and their behavior ? I seem to recall hearing from someone that Sperm whales have teeth and have on occasion been aggressive with small fishing boats but I don't know if that's a sea myth or not.
