Haha, my G. glabrous was attacked by his first prey item in captivity, a beach crab. It went up to him and he scoped it out with his antennae. The crab pinched his antennae and held on tightly....my mantis, now extremely angry, landed a single forceful blow to the underside of the crab, sending it flying with a cracked shell and two legs missing. The pincer that was pinching the mantis' antennae was still clamped tight, and snapped off the flying crab. I had to use my tongs to hold the claw while my mantis levered it's legs against the burrow wall to tug itself free...
