“…In sympatric cases, colour morphs were shown to develop in ecological allopatry by occupying different depth zones. This was observed for gopher/black-andyellow rock® sh (Sebastes carnatus, S. chrysomelas), cabrilla seabass (Serranus scriba) (Larson 1980;DeMartini & Donaldson 1996;Medioni et al 2001) and arc-eye hawk® sh (Paracirrhites arcatus). However, no ® xed genetic differences between colour morphs were found in any of these cases (Alesandrini & Bernardi 1999;Medioni et al 2001;G.…”

Coloration patterns of tropical reef ® shes is commonly used for taxonomic purposes, yet few studies have focused on the relationship between species boundaries and coloration types. The three-spot damsel® sh (Dascyllus trimaculatus) species complex comprises four species that vary both in geographical ranges and colour patterns making them an ideal model to study these relationships. We analysed the mitochondrial control region of 122 individuals from all four species collected from 13 localities. Individuals from two species (Dascyllus albisella and D. strasburgi) grouped into monophyletic clades, while the two other species (D. trimaculatus and D. auripinnis) were found to be paraphyletic. Coloration patterns were therefore not found to be good predictors of genetic isolation. In contrast, geographical origin was always consistent with the observed genetic pattern.

“…Coral reef fishes are widely appreciated for the dramatic differences in body colour among species (DeMartini and Donaldson 1996;Randall et al 1997;Marshall 2000). However, distantly related pairs of species exhibiting striking similarities in colour are relatively common, suggesting that mimicry might have been important in the evolution of this group (Wickler 1965;Russell et al 1976;Thresher 1978).…”

A number of potential mimetic relationships between coral reef fishes have been described, but the underlying mechanisms are poorly understood. Similarities in colour between species have often been attributed to aggressive mimicry (where predators resemble models in order to deceive prey), however this has not been tested. The fang blenny, Plagiotremus rhinorhynchos is a specialized predator that feeds on tissues of other fishes. Some individuals appear to mimic the harmless cleaner wrasse Labroides dimidiatus in order to deceive fish visiting cleaning stations, thereby increasing access to food. In this study, the ecological relationship between the mimic and model was examined at Kimbe Bay (Papua New Guinea) and the hypothesis that colour similarities represent facultative aggressive mimicry was experimentally evaluated. Some juveniles exhibited a striking resemblance to the juvenile colouration of the cleaner wrasse, but only when in close proximity to the wrasse and only when similar in size. As predicted for mimics, P. rhinorhynchos co-occurred with L. dimidiatus, but was rare relative to the model. Among site comparisons showed that the abundance of mimetic type blennies was positively correlated with the abundance of juvenile cleaner wrasses. Approximately 50% of all P. rhinorhynchos were found

“…Colour polymorphisms are particularly common among reef fishes (Randall and Randall 1960;Thresher 1978;Marliave 1985;Fautin and Allen 1992;DeMartini and Donaldson 1996). Although they provide a wealth of opportunities for testing theoretical explanations for the maintenance of colour morphs within populations, few such investigations have been carried out.…”

“…There are, however, a variety of reef fishes in which colour polymorphisms are not linked to sexual function (Thresher 1978;Lindquist 1980;DeMartini and Donaldson 1996), and therefore other mechanisms must also be involved in the evolution and maintenance of colour variation. The mechanisms favouring colour polymorphisms in these species remain elusive (DeMartini and Donaldson 1996), although the co-occurrence of numerous distinct colour variants in the hamlets (Hypoplectrus, Serranidae) has been attributed to aggressive mimicry (Randall and Randall 1960;Thresher 1978).…”

Ecological mechanisms for coexistence of colour polymorphism in a coral-reef fish: an experimental evaluation

The evolution of different colour morphs and how they are maintained in animal populations is poorly understood. We investigated the mechanisms maintaining yellow and brown morphs of a coral-reef fish, Pseudochromis fuscus, at Lizard Island, on the Great Barrier Reef. Histological examination of the gonads revealed that colour morphs were not sex-limited, therefore sexual selection does not appear to promote dichromatism in this species. The field distributions of the two colour morphs were spatially segregated, limiting the opportunity for negative frequency-dependent selection to operate. Our results support another ecological mechanism of coexistence. The yellow morph occurred in deeper areas, usually close to the reef edge, where there was a proportionally high cover of live branching corals. In contrast, the brown morph occurred in shallower areas, more distant from the reef edge, that were proportionally low in live branching corals. Within these habitats, each colour morph of P. fuscus displayed a close association with similar coloured damselfishes from the genus Pomacentrus. The yellow morph was associated with predominantly yellow damselfishes (P. moluccensis and P. amboinensis) and the brown morph with darker coloured species (P. adelus and P. chrysurus). Multiple-choice experiments in the laboratory revealed that: (1) each colour morph of P. fuscus preferentially selected habitat patches occupied by damselfishes with the same colouration; and (2) differences in microhabitat use between the two colour morphs of P. fuscus were due to the presence of different coloured damselfishes in these microhabitats. P. fuscus is a predator of newly recruited damselfishes and the striking resemblance between each morph of P. fuscus and the damselfish with which it was associated, suggests that aggressive mimicry may promote coexistence of P. fuscus colour morphs.
