Monster Manual
Giant crocodiles can grab and hold creatures of Large or smaller size.
Combat Grab (Ex): To use this ability, crocodile must hit a Large size or smaller opponent with its bite attack. If it gets a hold, the crocodile grabs the opponent with its mouth and drags it into deep water, attempting to pin it to the bottom. The crocodile automatically deals bite damage each round it maintains the pin.
Skills: A crocodile gains a +12 racial bonus to Hide checks when submerged.
