Description edit
The male is black with light color in the back of the body, the female is gray with black, and juveniles are yellow and black.[3][4]
Distribution and population edit
The countries and territories that it occurs in include American Samoa, Australia, British Indian Ocean Territory, China, Christmas Island, Cocos Islands, Comoros, Cook Islands, Fiji, French Polynesia, Guam, India, Indonesia, Japan, Kenya, Kiribati, Madagascar, Malaysia, Maldives, Marshall Islands, Mauritius, Mayotte, Micronesia, Mozambique, Myanmar, Nauru, New Caledonia, Niue, Northern Mariana Islands, Oman, Palau, Papua New Guinea, Philippines, Réunion, Samoa, Seychelles, Singapore, Solomon Islands, Somalia, South Africa, Taiwan, Tanzania, Thailand, Tokelau, Tonga, Tuvalu, United States Minor Outlying Islands, Vanuatu, Vietnam, Wallis and Futuna and Yemen.
Given its wide range, the exact population is unknown, but it is considered relatively common (except in the Philippines and Malaysia, where it is rare in some sites).
Habitat and ecology edit
It is found in abundant coral areas from sub-tidal reef flats to deeper lagoons and seaward reefs and has a depth of 40 meters. Unlike other cleaner wrasses, this fish spans larger areas to clean and is cleans more during the day when it is active. It, both individually and in groups, feeds on fish mucus and crustacean ectoparasites such as the Gnathiidae, and has been found to clean and interact with a variety of species, including the striated surgeonfish, the brown tang, parrotfish and the closely related bluestreak cleaner wrasse.[5] It also cleans sharks and rays, such as the grey reef shark and the whitetip reef shark. [6] At night, it may sleep in a mucous cocoon.
Like other cleaners, Labroides bicolor will dance as a form of communication and may also dance to reduce client aggression.[7]
Conservation edit
It is listed as Least Concern by the IUCN and it not considered to be significantly threatened although it was once was targeted by the aquarium industry, and coral degradation may occur in some parts of its range. It occurs in several protected areas throughout its range but research is needed on sustainable harvest and trade and the impact of collection.
