I assume that a fast "finger-walk" up the carapace past the claws, hard grab, and shake them loose works here too?
Sometimes, if they are not too far back and if there is enough arm room, and if you are not claustrophobic or dealing with too much water movement, and if your gloves can handle those sharp tail spines. Direct bright light will spook them, so you have to keep them in the beam's outer edge. It's like juggling. Scare them and they go deep into the jetty.
Lobsters are cannibals. I once got a small monster that I'd missed a dozen times by staking my bug bag to a small rock with a couple of occupants in it, directly in front of the lair. 20 minutes later I kicked straight down from the surface (only about 15 feet) able to just make out the yellow bag and caught the bug by the thinnest of margins using only moonlight and guesswork. To be that young again...
I've lost quite a few that left just a claw in my hand. Those were eaten for breakfast.
