My question pertains to the heat generated by a pistol shrimp claw. The snap creates a void that generates massive heat. What would be the output of energy from a mechanical claw if a superconductor rod could be placed within contact distance of said void.

Please clarify your question. I don't see what a superconductor has to do with the amount of energy involved in the collapse of a bubble generated by the snapping claw of a pistiol shrimp. A superconductor transports electricity with no loss, and has nothing to do with transporting either mechanical energy or heat.
