The enormous head of this man-sized amphibian is nearly all mouth. Two eyes sit atop its head, and its raised nostrils give it a somewhat crocodilian appearance. Its body is long and flat.

Paracyclotosaurus are giant amphibians although they can live on dry land, Paracyclotosaurus spend most of its time in water. A fish-eater, it lies just below the surface of the water. When an unsuspecting fish come within reach of its jaws, Paracyclotosaurus lifts its massive head, its mouth opened wide and the fish was sucked inside. Paracyclotosaurus was 6–8 feet long, and it lived in the Triassic period.   Paracyclotosaurus is a larger relative of eryops. Spending more of its time in the water, it is a faster swimmer, but extremely slow on land.   A paracyclotosaurus is 6 to 8 feet long, weighing around 300 pounds.

Like a crocodile, a paracyclotosaurus often hides the bulk of its body underwater, with only its eyes and nostrils breaking the surface. It sucks fish and other small prey into its huge mouth, swallowing them whole.

Improved Grab (Ex): To use this ability, a paracyclotosaurus 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 try to swallow the foe the following round.

Swallow Whole (Ex): A paracyclotosaurus can try to swallow a grabbed opponent of up to two sizes smaller by making a successful grapple check. The swallowed creature takes 1d10+4 points of bludgeoning damage and 1d4 points of acid damage per round from the gizzard. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 10 points of damage to the gizzard (AC 11). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out.

A Medium paracyclotosaurus’s gizzard can hold 2 Tiny, 8 Diminutive, or 16 Fine opponents.

Vortex Maw (Ex): A paracyclotosaurus can open its mouth so quickly that it creates a powerful suction. All creatures within a 10-foot cone must make Strength checks opposed by the paracyclotosaurus’s Strength check (+4 for a standard paracyclotosaurus), with the same modifiers as a bull rush. If the paracyclotosaurus beats a creature’s Strength check result, it pulls the victim 5 feet closer to its jaws. For each 5 points by which its check result is greater than a victim’s check result, the paracyclotosaurus pulls the victim an additional 5 feet closer. The victim provokes attacks of opportunity if it is moved.

Skills: A paracyclotosaurus 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.

*A paracyclotosaurus gains a +4 racial bonus on Hide checks when in the water. Further, a paracyclotosaurus can lie in the water with only its eyes and nostrils showing, gaining a +10 cover bonus on Hide checks.
