SEWERGATOR
These aggressive predators range from 8 to 10 feet in length. Giant versions have been reported that can be up to 18' long. They lurk in the water showing only their eyes and nostrils.
   Sewergators are a stunted form of crocodile that live in urban sewers, underground pools and other shallow unground water sources.
Combat
   Improved Grab (Ex)  On a successful bite against a creature no larger than the sewergator, it will attempt to pull the victim underwater and hold it there, automatically doing bite damage each round that it maintains it's grip and possibly causing drowning (suffocation) damage
   Light Blindness  Sewergators dislike bright light and will try to avoid it. When unable, they are -1 on all attack, skill and saving DCs
   Skills  A sewergator gets a +8 racial bonus to Hide when underwater
