*SNIP*
Improved Grab (Ex): To use this ability, a marl must hit with a slam 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 and on its next turn can transfer a grabbed opponent to its constricting tail.
Constricting Tail (Ex): A marl can transfer grabbed victims from a slam to its tail as a move action. Although it lacks a tail slap attack, it can constrict with its powerful tail, dealing 6d6(?) points of damage with a successful grapple check.
