Couple in the making
A pair of Ribbon Eels - Rhinomuraena quaesita.
They have 3 phases :
- black/yellow during juvenile phase
- blue/yellow during male phase
- fully yellow during female phase
The picture shows a slightly bigger male slowly changing to female phase, with yellow colouration on the body.
The ribbon eel (Rhinomuraena quaesita) or Bernis eel, is a species of moray eel, the only member of the genus Rhinomuraena. The ribbon eel is found in lagoons and reefs in the Indo-Pacific ocean, ranging from East Africa to southern Japan, Australia and French Polynesia.
