Improved Grab (Ex): To use this ability, a werecrocodile in animal form 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 the werecrocodile wins the grapple check, it establishes a hold on the opponent with its mouth, drags it into deep water, and attempts to pin it to the bottom.

Alternate Form (Su): A werecrocodile can assume the form of a crocodile or a crocodile-human hybrid.

Crocodile Empathy (Ex): A werecrocodile can communicate with crocodiles and giant crocodiles. It gains a +4 racial bonus on Charisma-based checks against such creatures.

Curse of Lycanthropy (Su): Any humanoid or giant hit by the bite attack of a werecrocodile in animal or hybrid form must succeed on a DC 15 Fortitude save or contract lycanthropy.

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

Skills: A werecrocodile in animal or hybrid form 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 werecrocodile in animal or hybrid form gains a +4 racial bonus on Hide checks when in the water. A werecrocodile in animal form can lie in the water with only its eyes and nostrils showing, gaining a +10 cover bonus on Hide checks.

A werecrocodile prefers to catch potential enemies unaware by assuming its humanoid or giant form and posing as a harmless commoner. It then changes to crocodile form and attacks as soon as its prey comes within range.
