Crocodiles (especially the overstudies Nile crocs) are very cooperative during
feeding time. They still fall under the terrestrial hunter category since they
do take down terrestrial prey (ambush from below) on a regular basis. They
lack the cutting teeth as well, but when in trouble they get help from their
fellow crocodiles who will hold the carcass still while they rip pieces of it
off.

How many mammals act that tolerant during feeding time?
