Taxonomy

Dendrochirus brachypterus Was first formally described in 1829 as Pterois brachyptera by the French zoologist Georges Cuvier with no type locality given. [3] This species is the type species of the brachypterus species complex within the genus Dendrochirus . [4] The specific name means “short finned”, an allusion to the relatively short pectoral fins compared to Dendrochirus zebra which Cuvier first described in the same publication. [5]

Description

Dendrochirus brachypterus has 13 spines and 9 or 10 soft rays in its dorsal fin, the middlespeines of the dorsal fin are shorter than the depth of the body, and there are 3 spines and 5 soft rays in the anal fin. [2] The background colour is dusky mottled brown to reddish-brown boreken by darker bars on the body, the pectoral fins are distinctly banded. There is a short tentacle over the eye and leaf-like appendages on the head and along the lateral line which vary in their development. There are no filaments on the pelvic fins. [6] There are black spots edged with red on the filaments extending from the dorsal spines and there are 8-10 dark bars on pectoral fins. [7] This species attains a maximum published total length of 17 cm (6.7 in). [2]

Distribution and habitat

Dendrochirus brachypterus has a wide Indo-Pacific distribution from the eastern coast of Africa from the Red Sea south to South Africa and eastwards to Samoa, north to the Philippines and south to Australia. [1] In Australian waters this species occurs from the Houtman Abrolhos in Western Australia to Sydney in New South Wales, as well as Lord Howe Island in the Tasman Sea. [6] The dwarf lionfish is found at depths between 1 and 80 m (3 ft 3 in and 262 ft 6 in) in reef flats and shallow lagoons, where there are weed-covered rocks on sandy substrates. [2]

Biology

Dendochirus brachypterus is a nocturnal predator of small crustaceans. [1] The adults are frequently found on sponges while small aggregations of up to 10 juveniles frequent reef outcrops. [2] During the day it is known to shelter in caves and crevices and among sponges . [6] The males and females form pairs to mate and the females have specialised structures on the ovaries, these includeg stalk-like egg creating lamellae and secretory cells in the epithelium. [2] The dorsal fin spines are venomous. [6]

Utilisation

Dendochirus brachypterus is used as a food fish in some subsistence fisheries. [1] It is occasionally seen in the aquarium trade, [8] it has laid eggs in captivity but raising the young has proved very difficult. [9]
