Rhinomuraena quaesita - As its common name implies, R. quaesita has a long, slender, ribbon-like body, reaching approximately 4 feet in maximum length. Three fleshy filaments extend from the tip of the lower jaw, and a single filament is present on the snout. The ribbon eelââ¬â¢s nostrils are greatly enlarged, forming pronounced fanlike structures, which look rather like a set of rabbit ears. R. quaesita, a protandrous hermaphrodite males transition into females, goes through dramatic color changes as its gender transforms. Juveniles are black with a yellow dorsal fin. In males, the black coloration changes to blue with yellow on the lower jaw, snout, and dorsal fin. Females are bluish-/greenish-yellow to solid yellow. It was once thought that ribbon eels of each color phase actually represented different species altogether.
