Green Bird Wrasse

Overview

The Green Bird Wrasse is a distinctive reef-associated fish easily recognized by its elongated, beak-like snout. It is primarily found in the Indian Ocean, where it inhabits coral-rich lagoons and seaward reefs.

Distribution & habitat

This species is native to the Indian Ocean, ranging from East Africa and South Africa to the Andaman Sea. It typically frequents coral-rich areas and rocky reefs, often seen swimming near the substrate at depths of up to 35 meters.

Appearance

Adults are characterized by their unique, tubular snout, which they use to probe crevices for prey. The species exhibits sexual dimorphism; males are generally larger and display a vibrant blue-green coloration with a pale margin along the pectoral fin and lime-green accents on the fins. Females are typically smaller and show a different color pattern, often featuring a pale lower head and breast, a dark stripe through the eye, and yellow tones in the tail and anal fins. Juveniles are paler with a dark streak extending from the snout through the eye.

Biology & behavior

This is a solitary, diurnal species known for its unique swimming style, which involves a winding motion created by flapping its pectoral fins. Like many wrasses, it is a protogynous hermaphrodite, meaning individuals can change sex from female to male. During the breeding season, they engage in distinct pairing and may exhibit haremic or lek-like mating systems influenced by lunar cycles.

Feeding

As an active carnivore, it uses its specialized snout to hunt for small benthic invertebrates, including crustaceans, mollusks, and brittle stars. It may also consume small fish and will occasionally strike larger prey against rocks to break them into manageable pieces.
