click click click

so i was pretty sure i was hearing things over the last few months, now im sure. im hearing a lot of clicks, they seem pretty loud. is there any way to tell from the sound if its a mantis or a pistol? ive seen a few dead snail, hermit shells around. also ive found a few dead hairy crabs so im leaning towards a mantis.

if it is a mantis, what do i do? can it just stay in there or should i try an get it out? just outa curiosity how bad can these things hurt you? and will it bring down the rock if he keeps banging away?
