Description

Male specimen Genicanthus caudovittatus male.jpg
Male specimen

Genicanthus caudovittatus shows sexual dichromatism, the males and females have differing colouration. The males are whitish-blue marked with vertical dark brown barring and a black band running along the middle of the dorsal fin base. The females are pale pinkish grey with a black band over the eye and a black band on the upper and lower margins of the caudal fin. Both sexes have a markedly forked caudal fin. [4] The dorsal fin contains 15 spines and 15–17 soft rays while the anal fin has 3 spines and 17–19 soft rays. This species attains a maximum total length of 20 centimetres (7.9 in). [2]

Distribution

Genicanthus caudovittatus is distributed in western Indian Ocean where it occurs along the eastern coast of Africa from the Red Sea in the north to KwaZulu-Natal in South Africa, east to Madagascar, Maldives, Mauritius, and Réunion. It has also been recorded from Weh Island off northwestern Sumatra. [1]

Habitat and biology

Genicanthus caudovittatus is found at depths between 15 and 70 metres (49 and 230 ft). [1] In the Red Sea it can be found in shallower water than in the Andaman Sea. [2] It can be found on steep outer reef slopes where it lives in small groups made up of a male and a few females. It feeds on plankton. [1] Juveniles live at greater depth than the adults. [5]

Systematics

Genicanthus caudovittatus was first formally described in 1860 as Holocanthus caudovittatus by the German-born British ichthyologist and herpetologist Albert Günther (1830–1914) with the type locality given as Mauritius. [6] The specific name is a compound of caudus meaning “tail” and vittatus meaning “banded”, referring to the black markings on the tail. [7]

Utilisation

Genicanthus caudovittatus occasionally appears in the aquarium trade. [1]
