Abstract

We report here, for the first time, the existence of a white colour morph Elacatinus figaro, an endemic threatened cleaner goby from the Brazilian Coast. The specimen from this study lived in a cleaning station along with other E. figaro. Records were made based on pictures and the specimen was collected and preserved for genetic studies. Although the strong bright yellow colour is of vital importance for attracting other fish to the cleaning station, we speculate that living alongside regular-coloured individuals can diminish the disadvantage of not having the flashy stripe.
