Giant gulpers are nothing more than a great maw followed by a long, trailing tail, designed to swallow prey as large as itself.
Typically about 12 feet long, giant gulpers are predators of the deep dark sea, who mindlessly hunt everything they encounter. Their small eyes can catch the miniscule amount of light that finds its way into these depths, but they mostly rely on their blindsight. A few giant gulpers sport a bioluminescent tail tip, for the purpose of attracting prey.
Combat
A giant gulper is straightforward in combat, attempting to swallow its prey as soon as possible. if faced with multiple opponents, it will try to devour the nearest first, while trying to constrict those who would come to the aid of the victim.
Constrict (Ex): With a successful grapple check, a giant gulper can constrict a grabbed opponent, dealing 1d6+6 points of bludgeoning damage.
Improved Grab (Ex): If a giant gulper hits an opponent of its own size or smaller with a bite attack, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity (Grapple bonus +18 - a giant gulper receives a +4 racial bonus to grapple checks due to its slanted teeth). If it gets a hold, it can swallow the opponent on its next successful grapple check. Alternatively, the giant gulper has the option to conduct the grapple normally, or simply use its bite to hold the opponent (-20 penalty on grapple check, but the giant gulper is not considered grappled). In either case, each successful grapple check it makes during successive rounds automatically deals bite damage.
Swallow Whole (Ex): A giant gulper can swallow a single creature of its own size or smaller by making a successful grapple check (grapple bonus +18), provided it already has that opponent in its maw (see Improved Grab, above). Once inside the giant gulper, the opponent takes 2d6+6 points of crushing damage and 1d8 points of acid damage per round fromn the giant gulper’s stomach. A successful grapple check allows the swallowed creature to climb out of the stomach and return to the giant gulper’s maw, where another grapple check is needed to get free. Alternatively, a swallowed creature can try to cut ts way out with either claws or a light piercing or slashing weapon. Dealing a total of at least 15 points of damage to the stomach (AC 9) in this way creates an opening large enough to permit escape. Once a single swallowed creature exits, muscular action closes the hole; thus, another swallowed opponent must cut its own way out. A giant gulper’s stomach can hold 1 Large, 4 Medium-Size, or 16 Small or smaller opponents.
Blindsight (Ex): A giant gulper can ascertain its surroundings using environmental clues such as currents.
