Swallow Whole (Ex)

When a Tylosarus begins its turn with an opponent grappled in its mouth (see Grab), it can attempt a new combat maneuver check (as though attempting to pin the opponent). If it succeeds, it swallows its prey, and the opponent takes bludgeoning damage (2d6+12). A swallowed creature can escape by doing 9 points of damage to the inside of the Tylosarus with a light slashing or piercing weapon (AC 16). A creature that escapes the pin while swallowed whole emerges from the Tylosarus’s stomach, not its throat, where it may be grabbed and pinned again.

This predatory marine lizard swims with four flippered limbs and a powerful, fluke-like tail. Its extended snout is filled with sharp teeth, and it feeds on both aquatic and surface prey. They are known to attack ships, mistaking them for basking whales or other creatures. A tylosaurus grows up to 50 feet in length and weighs 30,000 pounds.
