Gnaw (Ex) If a marine eel begins a round with a grabbed foe, it inflicts automatic bite damage (2d4+2 points of damage). A marine eel possesses a second set of jaws in its throat that aid in swallowing—it can make a second bite attack (+11 attack, 1d4+2) against a foe it has already grabbed.
The marine eel is a ferocious predator, capable of holding prey in its primary jaws while a smaller set of jaws inside its throat chews away bite-sized portions.
