How does the Zebrasoma genus differ from the Acanthurus genus in body shape?

Answer

*Zebrasoma* has a deep, laterally compressed, disc-shaped body.

The distinction between the genus *Zebrasoma* and the genus *Acanthurus*, although both belong to the surgeonfish family Acanthuridae, lies significantly in their morphology, particularly body profile and snout length. Fish belonging to *Zebrasoma*, including the Yellow Tang, are distinctly characterized by deep, laterally compressed, disc-shaped bodies. Furthermore, they possess elongated snouts specialized for grazing. In contrast, surgeonfishes classified under the *Acanthurus* genus typically exhibit a body shape that is more oval or elongated, accompanied by a relatively shorter snout compared to their *Zebrasoma* relatives. These consistent physical differences are key markers used to differentiate species within the family.
