The study of sex differences has produced major insights into the organization of animal
phenotypes and the regulatory mechanisms generating phenotypic variation from similar …

Teleost fishes are the 'champions' of sexual plasticity among vertebrates. Several species
have two male reproductive morphs with distinct suites of behavioral, somatic, neuronal …

Socially-controlled functional sex change in fishes is a dramatic example of adaptive
reproductive plasticity. Functional gonadal sex change can occur within a week while …

Teleost fishes are the most species-rich clade of vertebrates and feature an overwhelming
diversity of sex-determining mechanisms, classically grouped into environmental and …

Alternative reproductive tactics within one sex, adult sex or role change, and reproductive
suppression are all forms of reproductive plasticity commonly exhibited among teleost …

Fishes are the only vertebrates that undergo sex change during their lifetime, but even within
this group, a unique reproductive strategy is displayed by only 1.5% of the teleosts. This …

SPECIES with multiple sexual phenotypes provide novel insights into neuroendocrine
mechanisms underlying vertebrate sexuality. Many fish species are capable of socially …

Teleosts provide abundant opportunities to examine the physiological regulation of sexual
behavior. As in other vertebrates, hormones synchronize behavior with gonadal …

Fish show extraordinary sexual plasticity, changing sex naturally as part of their life cycle or
reversing sex because of environmental stressors. This plasticity shows that sexual fate is …

Teleost fish exhibit remarkably diverse and plastic patterns of sexual development. One of
the most fascinating modes of plasticity is functional sex change, which is widespread in …
