How does the morphology of the *Zebrasoma* genus contrast with the *Acanthurus* genus?

Answer

The *Zebrasoma* group is characterized by a compressed, disc-like body shape, unlike the more oval shape of *Acanthurus*.

Ichthyologists differentiate between various genera within the Acanthuridae family based on distinct morphological characteristics, which often reflect adaptations to different feeding mechanics or habitats. The *Zebrasoma* genus, which includes the Yellow Tang, is defined by its highly compressed, disc-like body profile. This physical structure is contrasted with that of the *Acanthurus* genus, whose members tend to possess a more oval body shape. Furthermore, the *Zebrasoma* lineage is also noted for having a protrusible snout. These physical divergences are significant indicators of evolutionary branching within the surgeonfish lineage, suggesting adaptations to specific ecological niches over time.
