This means that the trait evolved independently in these similar yet distinct species due to similar environmental pressures and conditions. For example, Dr.
Jones, whose team studies the evolutionary background and implications of the seahorse and pipefish mating strategies, suggests that males demonstrate choosiness among females and females compete among one another for males.

Studies of wild populations of the potbellied seahorse, Hippocampus abdominalishave found evidence of female-female competition and male mate choice, suggesting that natural populations of this species are sex-role reversed [ 35 ]. Seahorses are reproductively most active during the first hours of daylight Vincent and Sadler ; Masonjones and Lewis Observed and expected allelic combinations.
Received : 22 November Recent empirical evidence indicates that sex roles may shift rapidly within a single breeding season according to ecological resources and availability of partners Forsgren et al. Published online Jun Seahorses have a unique mode of reproduction: male pregnancy.
