A boalisk hunts by grabbing prey with its mouth and then squeezing with its powerful body. More powerful opponents (or if the boalisk has recently eaten) will be attacked with the boalisk's gaze attack.

Improved Grab (Ex): To use this ability the boalisk must hit with its bite attack. If it gets a hold, it can constrict.
