Improved Grab (Ex): To use this ability, the dire shark must hit with its bite attack. If it gets a hold, it can try to swallow the foe.

Swallow Whole (Ex): A dire shark can try to swallow a grabbed opponent of Large or smaller size by making a successful grapple check. Once inside, the opponent takes 2d6+6 points of crushing damage plus 1d8+4 points of acid damage per round from the shark's digestive juices. A swallowed creature can cut its way out using claws or a light slashing weapon by dealing 25 points of damage to the shark's digestive tract (AC 20). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. The shark's gullet can hold two Large, four Small, eight Tiny, sixteen Diminutive, or thirty-two Fine or smaller opponents.

Keen Scent (Ex): A dire shark can notice creatures by scent in a 180-foot radius and detect blood in the water at ranges of up to a mile.
