This amphibian is the size of a large crocodile, with a long, slender body and short legs. Its crocodilian head bears a maw filled with sharp teeth.

Eogyrinus hunt prey much like crocodiles, hiding the bulk of its body underwater, with only its eyes and nostrils breaking the surface. It grabs prey that approaches the water, drags it under, and attempts to rip it apart with its death roll.
Death Roll (Ex): An eogyrinus that successfully gets a hold on an opponent with its improved grab ability lodges its prey against natural terrain or even another eogyrinus, then bites down hard and twists its body to tear off large pieces of meat. If another eogyrinus joins the grapple, both eogyrinuses deal maximum damage. This attack deals bite damage each round until the victim breaks free, the eogyrinus is slain, or the victim dies.
Improved Grab (Ex): To use this ability, an eogyrinus must hit an opponent of up to one size smaller 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, it establishes a hold and can use its death roll in the following round.
Skills: An eogyrinus has a +8 racial bonus on any Swim check to perform a 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.
