The kisspeptin system is increasingly recognised as a central regulator of reproductive physiology in fish. Unlike mammals, teleosts often harbour two or more kisspeptin genes (e.g. Kiss1 and Kiss2) ...

Even accounting for their proportionate size, bigger female fish produce many more offspring than smaller fish, a new study reveals. The results hold implications for fisheries managers, since climate ...

Researchers from Institute of Science Tokyo present the underlying reasons behind the evolutionary bias in reproductive strategies of egg-care species. Using 240 whole genome sequences of fish species ...

Parental egg-care in fish traps them in an evolutionary dead-end through the loss of the chorion-hardening system, according to scientists from the Institute of Science Tokyo. Fish have diverse ...

A mussel has been captured on video flapping its mantle in an attempt to lure a fish to involuntarily serve as a host for its larvae. The short clip, which was posted online by the West Virginia ...

The ocean is home to a vast array of different animals, each with its own traits. These include different forms of mating, such as parasitic mating. Parasitic mating occurs when the male physically ...
