Re: Tyrannosaurus had most powerful bite of any land animal

You're right, but the first link included comparison with the bite of
the white shark.

Jaime's point on the enhanced need of force in opening or closing the
jaws because of water viscosity is good, and makes me wonder if that
has something to do with the relatively strong jaw musculature in
crocodiles compared to other groups of tetrapods (I do not know about
whales), or the preference for suction feeding in many
actinopterygians and some other aquatic vertebrates (in part to avoid
being over-muscled, or because the viscosity of water much slows a
biting movement which is not good when catching fast prey). The long
and narrow jaws of many crocodilians may be another way to avoid
displacing a large volume of water. I wonder if the downcurved gape of
many actinopterygians may permit to increase the biting force thanks
to water resistance to advance when the fish keeps advancing whereas
