“…By contrast, in the viviparous Goodeid fish Girardinichthys multiradiatus, males sometimes display a dark, female-like 'pregnancy' spot around their vent. Subordinate males with dark spots attract fewer aggressive maneuvers by dominant males, who appear to mistake them for females and consequently court them [25]. This diversion of aggressive behavior into courtship behavior affords subordinate males greater opportunities to sneak copulations with females [25].…”

“…Generating heritability estimates in a model organism would not only identify same-sex behaviors that are potential targets of selection but would also allow researchers to use quantitative genetic models incorporating IGEs to predict whether same-sex sexual behaviors alter the strength of selection on other traits. These could include 8 behaviors such as courtship in Drosophila [25], or morphological features such as the armature found in both male and female African bat bugs (Afrocimex constrictus) that protects against traumatic insemination [30].…”

Same-sex sexual behavior has been extensively documented in non-human animals. Here we review the contexts in which it has been studied, focusing on case studies that have tested both adaptive and non-adaptive explanations for the persistence of same-sex sexual behavior. Researchers have begun to make headway unraveling possible evolutionary origins of these behaviors and reasons for their maintenance in populations, and we advocate expanding these approaches to examine their role as agents of evolutionary change. Future research employing theoretical, comparative and experimental approaches could provide a greater understanding not only of how selection might have driven the evolution of same-sex sexual behaviors but also ways in which such behaviors act as selective forces that shape social, morphological and behavioral evolution.Why does same-sex sexual behavior matter? Same-sex sexual behavior in animals has long fascinated scientists as well as non-scientists. Previous work has emphasized the apparent paradox of selection acting on non-reproductive individuals [1,2], but little is known about the evolutionary consequences of such behavior, whether it occurs as exclusive life-long pairing or as a part of other sexual interactions. The variety and ubiquity of same-sex sexual behavior in animals is impressive; many thousands of instances of same-sex courtship, pair bonding and copulation have been observed in a wide range of species, including mammals, birds, reptiles, amphibians, insects, mollusks and nematodes (Table 1). These observations are likely to be underestimates of the frequency of such interactions, partly because researchers assume that pairs in sexually monomorphic species that are engaging in sexual behavior must be opposite sexes.From an evolutionary perspective, same-sex behavior has been viewed as a puzzle requiring a special explanation, rather like suicide or adoption of unrelated infants [3]. Why would animals engage in sexual behaviors that do not directly result in reproduction? It is clear that lifelong same-sex orientation is unlikely to evolve and, indeed, few examples of life-long pairings in wild animals exist, but the persistent and well-documented occurrence of same-sex sexual behaviors across nearly all taxonomic groups of animals is worth exploring.The purpose of this review is to expand our thinking about the evolutionary implications of same-sex behavior in animals. We suggest that the phenomenon needs to be Review Glossary Alternative reproductive behavior: different methods, mechanisms or strategies for attaining matings found within a single sex. Most often studied in males, alternative mating tactics might be purely behavioral, or might be associated with different morphologies. Cooperative breeding: social structure in which individuals forgo reproduction and provide care for others' offspring, such as feeding, grooming and protection from predation. Gay/lesbian: terms describing homosexual orientation in humans. In typical usage, implies a stereotyped set of lifestyle ch...

“…The giant cuttlefish, Sepia apama, which shows marked ability to modify its lateral colour pattern, was reported to switch between female and male body colour patterns according to competitive status among males (Norman et al 1999). In captivity, subordinate males of the viviparous fish Girardinichthys multiradiatus display a ventral spot that is usually a pregnancy character of females, while dominant males show no such black spot (Macías-Garcia and Valero 2001). There have been few quantitative field studies regarding such flexible female mimicry in fish.…”

Status-dependent female mimicry in landlocked red-spotted masu salmon

We observed transient status-dependent female mimicry related to reproductive behaviour in landlocked red-spotted masu salmon (Oncorhynchus masou ishikawae). In females, the lower half of the lateral flank underwent solid blackening as an ovipositional character, and 70% of subordinate males showed a similar lateral pattern (M-type). In contrast, most of the paired males and 30% of subordinate males showed a different lateral pattern in which a melanic stripe ran along the lateral-line organ (N-type). It was possible to bring an M-type pseudo-fish model into closer proximity to a pair than an N-type model. In addition, the rate of successful sperm release in subordinate M-type males was higher than that in subordinate Ntype males. Males could transform between N-and M-types according to fluctuations in competitive status among the males. A digital video image related to the article is available at

“…There is no evidence of seasonality in the expression of these social behaviours. Females show mating preferences based on visual cues including UV vision (Macías Garcia et al 1994; Macías Garcia & Burt de Perera 2002), and males respond to visual cues displayed in social interactions (Macías Garcia & Valero 2001); thus, it appears that they have a well‐developed visual sense. We therefore predicted that these fish should be able to use local visual landmarks to locate a goal.…”

Amarillo Fish (Girardinichthys multiradiatus) Use Visual Landmarks to Orient in Space

Fish responsiveness to visual stimuli has been studied extensively in contexts such as female mate choice, predator inspection and schooling, yet surprisingly little work has been conducted on visual orientation in space in fish. Here we report on an experiment designed to test whether Amarillo fish can learn to find a goal within a maze more effectively in the presence of local visual landmarks than otherwise. We found that: (a) Amarillo fish can use landmarks to locate a goal, (b) there was no observed difference in the ability to use visual landmarks between two populations and (c) overall navigational performance differed between two populations of Amarillo fish: individuals from a permanently turbid eutrophic pond performed better than those from a pond with clear waters. We hypothesize that fish that inhabit clear waters possess poorer navigational capabilities than fish from turbid waters because they normally rely on goal‐oriented behaviour, which requires neither egocentric nor environmental clues to navigate. This paper adds to the literature on the links between habitat characteristics and population differences in performance.
