The term 'SERPENT THAT SQUEEZES' can be solved by the three-letter word BOA. Boas are a type of non-venomous snake found in tropical and subtropical regions of Central and South America, Africa, and Asia. They are constrictors, meaning they kill their prey by squeezing them until they can no longer breathe. Boas are typically large and heavy-bodied snakes, with some species reaching lengths of up to 13 feet.
