Dendrochirus biocellatus, the twospot turkeyfish, twinspot lionfish, twoeyed lionfish or ocellated lionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes and lionfishes. This species is widespread throughout the tropical waters of the Indo-West Pacific region, In the wild, the species eats small fish as well as shrimp. Taxonomy Dendrochirus biocellatus Was first formally described as Nemapterois biocellatus in 1938 by the American zoologist Henry Weed Fowler with the type locality given as off Jolo Light on Jolo Island in the Sulu Sea in the Philippines. This is the only species in the monotypic subgenus Nemapterois, this name being a compound of nema, meaning “thread” and Pterois, the genus of “typical” lionfishes. The specific name biocellatus means two spots, alluding to the two eye like spots, called ocelli, on the soft rayed part of the dorsal fin. Description Dendrochirus biocellatus has 13 spines and 9 soft rays in its dorsal fin with 3 spines and 5 soft rays in the anal fin, the middle spines in the dorsal fin are shorter than the depth of the body, with deep incisions in the fin membranes of that fin too. The large, wing-like pectoral fins have 20 or 21 fin rays with the upper rays fully connected by membranes, the lower rays being simple and their tips extend beyond the membrane. The tentacles on the lachrimal bone are long, their length being more than two times the diameter of the eye. The overall colour of this lionfish is reddish-brown. there are 2, sometimes 3, large black eye like spots, or ocelli, on the soft-rayed part of the dorsal fin, there are 3 pink to yellowish bars on the flanks. The pectoral fins are banded with pale and brown. This species attains a maximum total length of . Distribution and habitat Dendrochirus biocellatus has a wide Indo-Pacific distribution which extends from the western Mascarene Islands, The Maldives and Sri Lanka eastwards to the Mariana and Tuamotu Islands, north as far as southern Japan, south to New Caledonia and Tonga. In Australian waters it is found at Scott Reef off Western Australia, at the Ashmore and Hibernia reefs in the Timor Sea and at Christmas Island. This species is found at depths of in area where there is rich coral growth on reefs in clear water. Biology Dendrochirus biocellatus shelters in caves and on ledges during the day, emerging
