Lobster claws, also known as chelae (6 letters) and PINCERS (7 letters), are the two large claws of a lobster that are used for defense and capturing prey. They are made up of two parts: the crusher claw and the cutter claw. The crusher claw is used to crush shells and the cutter claw is used to cut food into smaller pieces. Lobster claws are powerful tools that allow lobsters to survive in their environment.
