Resumo: | We found yellowish juvenile coneys (Cephalopholis fulva) at Fernando de Noronha Archipelago, off Northeast Brazil, joining schools of similarly sized and coloured brown chromis (Chromis multilineata) when these latter closely approach the rocky reefs. Mingled within the mid-water hovering group of the plankton-feeding chromis, the piscivorous coney is able to approach unaware prey - an instance of aggressive mimicry. Three out of four coney individuals hunting under such disguise were successful in their attempts to prey on the otherwise wary rock-dwelling blenny (Malacoctenus species). This is the first instance of an epinepheline grouper mimicking a schooling and plankton-eating damselfish model in the West Atlantic.
