What term is commonly used to refer to the sharp, retractable spine on the caudal peduncle?
Answer
Scalpel
The most defining physical characteristic shared by the Yellow Tang and the broader surgeonfish family is the presence of a sharp, rigid, retractable spine situated on each side of the caudal peduncle, which is the narrow transition zone connecting the main body to the tail fin. Due to its resemblance to a precision surgical instrument, this defensive feature is universally referred to as the *scalpel*. This structure is deployed rapidly when the fish perceives a threat, serving as a primary deterrent against predators or rivals during territorial disputes. Handling these fish requires caution because contact with this spine can inflict a painful injury.
