Journal of Fish Biology, EarlyView.Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.

Phenotypic divergence may facilitate co‐occurrence in Acanthopagrus species (Family: Sparidae)
Journal of Fish Biology, EarlyView.Abstract Understanding why closely related species co‐occur is one fundamental question in ecology. The seabream genus Acanthopagrus Peters, 1855 (Sparidae) is broadly distributed across the Indo‐Pacific, with four species, A. arabicus and A. sheim (yellowfin group), and A. bifasciatus and A.
