Sexual differentiation of the brain occurs in all major vertebrate lineages but is not well
understood at a molecular and cellular level. Unlike most vertebrates, sex-changing fishes …

Anemonefishes are monogamous protandrous hermaphrodites that live in societies
structured by size-hierarchies that function as breeding queues. Within each group, the …

Teleost fish exhibit remarkable sexual plasticity and divergent developmental systems,
including sequential hermaphroditism. One of the more fascinating models of sexual …

Background Male and female vertebrates typically differ in a range of characteristics, from
morphology to physiology to behavior, which are influenced by factors such as the social …

Sequential hermaphroditism is a unique reproductive strategy among teleosts that is
displayed mainly in fish species living in the coral reef environment. The reproductive …

Background Teleost fishes exhibit remarkably diverse and plastic sexual developmental
patterns. One of the most astonishing is the rapid socially controlled female-to-male …

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 …

Zebrafish sex determination and sexual differentiation is complex. Neither sex
chromosomes, major sex-determining genes nor universal sex-linked markers have been …

Sex differentiation is a puzzling problem in fish due to the variety of reproductive systems
and the flexibility of their sex determination mechanisms. The Sparidae, a teleost family …

Background Sexually dimorphic mating behaviors differ between sexes and involve gonadal
hormones and possibly sexually dimorphic gene expression in the brain. However, the …
