Naso Tang (Naso lituratus)

Naso lituratus earns the nickname "lipstick tang" honestly — a streak of bright orange around the mouth against an otherwise gray-brown body, with a bold black-and-yellow patch at the tail. Unlike Zebrasoma and Acanthurus, Naso tangs carry their defensive spines in a fixed, non-folding position at the tail base, so the "scalpel" is permanently drawn.
