“…spots of other colours, tail size), but that does not seem to be the case for guppies from the three M. crenulatum sites that have already been examined [20]. Alternate evolutionary responses of females could include a heightened ability to separate responsiveness towards the lure from responsiveness towards the original targets of their bias, such as food or mates [4,40]. Selection could also favour enhanced anti-predator behaviours so that females could better elude prawns' attacks; this could explain the wariness of our sympatric females to the live crayfish.…”

Seeing orange: prawns tap into a pre-existing sensory bias of the Trinidadian guppy

Sensory bias, a predisposition towards certain signals, has been implicated in the origin of mate preferences in some species. A risk associated with these biases is that they can be co-opted by predators as sensory lures. Here we propose that the orange spots on the brown pincers of a diurnal, predatory species of prawn function as lures for Trinidadian guppies, which have a sensory bias for orange. We exposed female guppies to (i) a life-like model of this Trinidadian prawn with orange, green or no spots on the pincers or (ii) a live, novel (non-Trinidadian) crustacean (crayfish), also with spotted pincers. First, we provide evidence that guppies sympatric with the prawn recognized our model as a potential predator. Next, we found that guppies spent more time in the dangerous head region of the model prawn with orange-spotted pincers compared with unspotted pincers. Finally, we show that allopatric, but not sympatric, guppies spent more time in the vicinity of the head of a live crayfish when orange spots were added to its pincers than when brown spots were added. Our results suggest that the orange spots on prawn pincers can act as a sensory lure.

“…It is still possible that in goodeids, female bright colouration, although different from that of the males, is nevertheless determined by the same genes that produce There is some evidence of genetic correlation between male and female colour patterns in goodeids, but this is limited to one colour marking whose expression, in fact, has been suppressed in some species. The terminal yellow band (TYB), which in several goodeid species constitutes a sensory trap (Macías Garcia & Ramírez, 2005;Macías Garcia & Saldívar Lemus, 2012), is present in females of some species, but, interestingly, it is absent in the species where males exhibit the most conspicuous TYB (Ameca splendens; see Figure 1 in Macías Garcia & Ramírez, 2005 and Figure 3 in Macías Garcia & Valero, 2010). More commonly, female colourful marks are different from those of the males (Figure 3).…”

By preferring mates with increasingly costly ornaments or courtship displays, females cause an escalation of male reproductive costs. Such increased costs should promote male selectivity based on fecundity‐linked female attributes, leading to female ornamentation in species with traditional sex roles. Consequently, female ornamentation should evolve more frequently in taxa where male reproduction is costly than in comparable taxa where it is cheaper. We assessed the prevalence of female ornamental colouration in two clades of viviparous cyprinodontid fish: the Goodeinae, where stringent female choice imposes male mating costs, and the Poeciliinae, whose males can circumvent female mate choice. We found that although in the Poeciliinae female ornamental colour is a correlated, but paler version of male coloration, females of the Goodeinae often display vivid ornamental colours that are distinct from those of males. Thus, male and female ornaments are not (phylo)genetically correlated in the Goodeinae. Furthermore, phylogenetic signal on male and female colour is clearly detectable in the Poeciliinae, but absent in the Goodeinae, suggesting that ornamental colour of males and females in the latter may be the consequence of selection. Given that enforceable female choice has promoted male ornaments, we propose that evolutionary retribution has promoted distinct female ornaments in the Goodeinae.

“…For example, male water mites Neumania papillator exploit the females' feeding response by vibrating their legs to mimic the vibrations produced by their prey (Proctor, 1991). In several fish species within the sub-family Goodeidae, females show feeding behaviour towards a male ornament located on the tail fin (Macías Garcia & Ramirez, 2005;Macías Garcia & Lemus, 2012).…”

Does female feeding motivation affect the response to a food‐mimicking male ornament in the swordtail characin Corynopoma riisei?

Female response to various aspects of male trait morphology and the effect of female feeding motivation were investigated in the swordtail characin Corynopoma riisei, a species where males are equipped with a flag-like food-mimicking ornament that grows from the operculum. Unfed females responded more strongly to the male ornament and showed a stronger preference for larger ornaments than did fed females. Females were shown not to discriminate between artificial male ornaments of either undamaged or damaged shape.
