Tripletail Maori Wrasse

Overview

The Tripletail Maori Wrasse is a distinctive reef-dwelling fish known for its ability to rapidly shift colors and patterns. It is a shy, solitary predator that inhabits tropical waters across the Indo-Pacific region.

Distribution & habitat

This species is widely distributed throughout the Indo-Pacific, ranging from East Africa to the Tuamotu and Austral islands, and extending north to Japan and south to New Caledonia. It typically frequents coral-rich environments, including lagoons, seaward reefs, and rocky or sandy bottoms, often sheltering in areas with abundant algae or hydrozoans.

Appearance

Adults are characterized by a moderately deep, compressed body and a prominent head with thick lips. Their most striking feature is the caudal fin, which in males develops into a trilobed shape with elongate upper and lower lobes. The body coloration is highly variable, ranging from green to brown with mottled purple and red markings, often featuring four vertical dark bars. The head is decorated with small red spots and radiating red lines around the eyes.

Biology & behavior

These wrasses are diurnal and territorial. Like many members of the Labridae family, they are protogynous hermaphrodites, meaning they are born female and some individuals transition into males as they mature. They are generally elusive and difficult to approach in the wild.

Feeding

As a predator, the Tripletail Maori Wrasse primarily feeds on shelled benthic invertebrates, including various mollusks and crustaceans. It may occasionally consume small fish.
