Resumen
We describe a possible example of social mimicry between Octopus insularis and the small grouper Cephalopholis fulva, which frequently associate during foraging at Fernando de Noronha Archipelago, Brazil. The octopus, when swimming backwards, jet-propelled, becomes similar in colour and shape to accompanying C. fulva individuals and is therefore less conspicuous within the fish group. We regard this as an instance of social mimicry, a form of protection against visually-oriented predators in which different species similar in shape and colour mingle for the advantage of grouping. Even when swimming backwards alone, O. insularis may become similar to foraging C. fulva individuals, another putatively protective behaviour. We suggest that the feeding association commonly found between O. insularis and C. fulva minimized the evolutionary costs for the origin of mimicking by the octopus. © 2009 Taylor & Francis. 43 3-4 185 190 Cheney, K.L., Grutter, A.S., Marshall, J., Facultative mimicry: Cues for colour change and colour accuracy in a coral reef fish (2008) Proc R Soc Lond, 275, pp. 117-122 Dafni, J., Diamant, A., School-oriented mimicry, a new type of mimicry in fishes (1984) Mar Ecol Prog Ser, 20, pp. 45-50 Hanlon, R.T., Cephalopod dynamic camouflage (2007) Cur Biol, 17, pp. 400-404 Hanlon, R.T., Conroy, L.A., Forsythe, J.W., Mimicry and foraging behaviour of two tropical sand-flat octopus species off North Sulawesi, Indonesia (2008) Biol J Linn Soc, 93, pp. 23-38 Hanlon, R.T., Forsythe, J.W., Joneschild, D.E., Crypsis, conspicuousness, mimicry and polyphenism as antipredator defences of foraging octopuses on Indo-Pacific coral reefs, with a method of quantifying crypsis from video tapes (1999) J Linn Soc, 66, pp. 1-22 Hanlon, R.T., Messenger, J.B., (1996) Cephalopod behaviour, , Cambridge UK, Cambridge University Press Hochberg, F.G., Norman, M.D., Finn, J., Wunderpus photogenicus n. gen. and sp., a new octopus from the shallow waters of the Indo-Malayan Archipelago (Cephalopoda: Octopodidae) (2006) Molluscan Res, 26, pp. 128-140 Humann, P., Deloach, N., (2002) Reef creature identification: Florida, Caribbean and Bahamas, , Jacksonville FL, New World Publications Humann, P., Deloach, N., (2002) Reef fish identification: Florida, Caribbean and Bahamas, , Jacksonville FL, New World Publications Krajewski, J.P., Bonaldo, R.M., Sazima, C., Sazima, I., The association of the goatfish Mulloidichthys martinicus with the grunt Haemulon chrysargyreum: An example of protective mimicry (2004) Biota Neotrop, 4, pp. 1-4 Leite, T.S., Haimovici, M., Molina, W., Warnke, K., Morphological and genetic description of Octopus insularis, a new cryptic species in the Octopus vulgaris complex (Cephalopoda: Octopodidae) from the tropical western Atlantic (2008) J Mollusc Stud, 74, pp. 63-74 Mäthger, L.M., Barbosa, A., Miner, S., Hanlon, R.T., Color blindness and contrast perception in cuttlefish (Sepia officinalis) determined by a visual sensorimotor assay (2006) Vision Res, 46, pp. 1746-1753 Moland, E., Eagle, J.V., Jones, G.P., Ecology and evolution of mimicry in coral reef fishes (2005) Oceanogr Mar Biol, 43, pp. 455-482 Moynihan, M., Social mimicry: Character convergence versus character displacement (1968) Evolution, 22, pp. 315-331 Nemtzov, S.C., Diel color phase changes in the coney, Epinephelus fulvus (Teleostei, Serranidae) (1993) Copeia. 1993, pp. 883-885 Norman, M.D., Finn, J., Tregenza, T., Dynamic mimicry in an Indo-Malayan octopus (2001) Proc R Soc Lond, 268, pp. 1755-1758 Randall, J.E., A review of mimicry in marine fishes (2005) Zool Stud, 44, pp. 299-328 Randall, J.E., McCosker, J.E., Social mimicry in fishes (1993) Rev Fr Aquariol, 20, pp. 5-8 Sazima, C., Krajewski, J.P., Bonaldo, R.M., Sazima, I., Nuclear-follower foraging associations of reef fishes and other animals at an oceanic archipelago (2007) Environ Biol Fish, 80, pp. 351-361
