Comet, Calloplesiops altivelis (Steindachner 1903)

More Info


Distribution

Recorded in Australia from Northwest Cape, WA, One Tree Island, QLD, reefs in the Coral Sea (Lihou Reef and Coringa Islets), and Christmas Island in the Indian Ocean. The species occurs elsewhere in the tropical, Indo-west-central Pacific.

Inhabits outer reefs, sheltering in caves, crevices, holes and under ledges during the day.

Features

Dorsal fin XI, 8-10; Anal fin III, 9. 


Colour

Head and body brownish black with small pale blue spots; vertical and pelvic fins dark orange-brown, with many small blue spots; blue ringed black ocellus above base of last 3 dorsal rays; yellow spots at base of upper caudal rays; pectoral rays bright yellow, fin membrane transparent.

Biology

Females lay demersal eggs that are guarded by the male parent until the larvae hatch.

Remarks

The false eyespot on the rear of the dorsal fin is thought confuse predators. When threatened, comets may expose the rear of the body including the eyespot, and are thought to resemble the head of the Whitemouth Moray, Gymnothorax meleagris (McCosker 1978).
