Cavern lizards are aggressive ambush hunters. They prefer to scale the walls and wait for prey to pass underneath them where they drop down on their unsuspecting meal. In most battles, once a cavern lizard bites, it hangs on until its opponent is dead. If facing more than one foe, it won't employ this tactic so as not to leave itself defenseless against other aggressors. If cornered or extremely hungry, a cavern lizard fights to the death; otherwise, it retreats if facing a particularly powerful opponent.
