Improved Grab (Ex): To use this ability, a crocodile must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, the crocodile establishes a hold on the opponent with its mouth and drags it into deep water, attempting to pin it to the bottom.

Hold Breath (Ex): A crocodile can hold its breath for a number of rounds equal to 4 x its Constitution score before it risks drowning.

Skills: A crocodile has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line. *A crocodile gains a +4 racial bonus on Hide checks when in the water. Further, a crocodile can lie in the water with only its eyes and nostrils showing, gaining a +10 cover bonus on Hide checks.
