Improved Grab (Ex): To use this ability, a moray eel must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold. Moray eels gain a +4 racial bonus on grapple checks.

Powerful Bite (Ex): The moray eel gains a +2 racial bonus on damage rolls with its bite attack, and threatens a critical hit on a 19-20.

Aquatic Subtype

Creatures with the aquatic subtype always have swim speeds and thus can move in water without making Swim checks. An aquatic creature can breathe underwater. It cannot also breathe air unless it has the amphibious special quality.
