当今的真棒鱼聚光灯以广受欢迎的属为特色Cirrhilabrus, more affectionally known as the Fairy Wrasses.cirrhilabrus rubrimarginatus是一种常见的物种广泛分布在穿越s much of the Western Pacific, from Japan through to the Philippines, Palau, Indonesia, Vanuatu, Fiji and Tonga. It was first known from the Ryukyus peninsula and was officially described in 1992 along withCirrhilabrus katherinae。The most distinctive feature of this species is the broad red margin that decorates the dorsal and caudal fins in both sexes. This trait of course is a direct translation from its specific epithetrubrimarginatus。
红色边缘仙女wrasse是一种适中的物种，能够达到12厘米（〜5英寸）的长度。该物种可疑地相关C. lineatuswhich replaces it in the other parts of the Western Pacific such as New Caledonia and Australia. Like all members of the genus,C. rubrimarginatusis a protogynous hermaphrodite, where terminal males are derived from sex changed females. The species is also haremic where males are outnumbered by females.
Cirrhilabrus和密切相关的Paracheilinusare remarkable for possessing the ability to “flash”, which is a term used when males of a given species display their nuptial coloration. The nuptial coloration differs from species to species, and in the wildly confusingParacheilinus, helps the females to identify the correct males during courtship – an evolutionary advantage so to speak.
