Abstract

Despite its high economic value to fisheries, little is known about the ecology of the recently described Lutjanus alexandrei. This is the first report on the array of colouration exhibited by this species in its natural habitats: coral reefs, algal beds and mangroves. Five colour patterns occur in L. alexandrei, and they are related to different life phases or behaviour. Variable colouration is shown on the head, body and fin edges. Colour patterns range from uniform to barred and blotched, from white to red and brown. This variable colouration is mostly related to camouflage on different backgrounds. Some of these patterns are also displayed during interspecific associations. Further investigations are necessary to expand our knowledge on the ecology of this recently described species.
