An aquatic reptile of incredible strength, the liopleurodon is among the largest carnivorous animals ever.
The liopleurodon is a solitary creature, gathering in pairs only during its mating season. Although they dwell in the oceans of the world, liopleurodons are air-breathers and must surface regularly to breathe. They often lurk along shorelines in relatively shallow water and aren’t above swimming into lagoons or large rivers in search of food to feed their massive bodies.
A liopleurodon often measures up to 80 feet in length, but incredibly massive and ancient liopleurodons measuring over 200 feet long are rumoured to exist in the world’s uncharted oceans.
Liopleruodons often hunt near ocean shorelines and aren’t afraid to surge out of the surf onto a beach to catch creatures that come too close to the edge of the sea. They attack with a powerful bite.
Frenzy (Ex): If a liopleurodon is reduced to less than half its normal maximum hit points, it flies into a terrible rage of frenzied activity. During a frenzy, the liopleurodon gains a +4 bonus to its Armour Class and attack rolls. Its swim speed gains a +30 foot bonus, and if it makes a full attack action, it gains an additional bite attack. The frenzy persists for 1 minute, after which the liopleurodon becomes fatigued. A liopleurodon cannot enter a frenzy while it is fatigued.
Improved Grab (Ex): To use this ability, a liopleurodon 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 liopleurodon can try to swallow a grabbed opponent of up to two sizes smaller by making a successful grapple check. The swallowed creature takes 2d8+8 points of bludgeoning damage and 8 points of acid damage per round from the liopleurodon’s gizzard. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 45 points of damage to the gizzard (AC 20). Once the creature exits, muscular action closes the hole; another swallowed creature must cut its own way out. A Colossal liopleurodon’s gizzard can hold 2 Huge, 8 Large, 32 Medium, or 128 Small or smaller opponents.
Hold Breath (Ex): A liopleurodon can hold its breath for a number of rounds equal to 8 times its Constitution score before it risks drowning.
Keen Scent (Ex): A liopleurodon can notice creatures by scent in a 180-foot radius, and it can sense blood in the water at ranges of up to a mile.
Skills: A liopleurodon 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.
