According to Wikipedia the green anaconda, Eunectes murinus, is notable for being one of the world’s largest snakes. Green anacondas can grow to more than 5.21 m (17 ft) in length and weigh 97.5 kg (215 lb). They are found east of the Andes in Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil, and on the island of Trinidad.

Constrict (Ex): An anaconda deals 1d6+16 points of bludgeoning damage with a successful grapple check against a target at least one size category smaller than itself.
Improved Grab (Ex): To use this ability, the an anaconda must hit an opponent at least one size category smaller than itself with either a bite or a tail slap attack. If it gets a hold, it automatically deals bite or tail slap damage each round that the hold is maintained, and it can constrict in the same round and attempt to swallow in the next round. If the an anaconda wishes, it can continue to attack with its tail or its bite (not both) while it grapples with its body, but it takes a –20 penalty on all grapple checks if it does so.
Scent (Ex): This ability allows an anaconda to detect approaching enemies, sniff out hidden foes, and track by sense of smell.
Skill Bonuses: An anaconda gains a +8 species bonus on Balance, Climb, and Swim checks and a +4 species bonus on Hide, Listen, and Spot checks.
Swallow Whole (Ex): If an anaconda begins its turn with an opponent one or more size categories smaller than itself held in its mouth, it can attempt a new grapple check as though trying to pin the opponent. If it succeeds, it swallows its opponent, automatically dealing bite damage. Once inside the an anaconda, the opponent takes bludgeoning damage equal to the anaconda’s tail slap attack plus 1d6 points of acid damage per round from the monster’s stomach. A successful grapple check allows the swallowed creature to climb out of the stomach and return to the an anaconda’s maw, where another successful grapple check is needed to get free. Alternatively, the swallowed creature can attack from inside the stomach using claws or a Small or Tiny slashing weapon. Dealing at least 30 points of damage to the stomach (Defense 18) 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 creature must cut its own way out. A Huge anaconda’s stomach can hold 1 Large, 2 Medium-size, 8 Small, 32 Tiny, or 128 Diminutive or smaller opponents.
