An international research team has discovered a new pygmy seahorse species in Sodwana Bay in South Africa, the first of its kind to be found in the waters around the continent.

The direction of ocean currents can determine the direction of gene flow in rafting species, but this depends on species traits that allow for rafting propensity. This is according to a City College of New York study focusing on seahorse and pipefish species. And it could explain how high genetic diversity can contribute to extinction in small populations.

Embryonic development in the womb is a complicated process that is still puzzling today. In particular,researchers have not determined how the paternal genetic information present in the embryo are tolerated by the maternal immune system and not rejected upon recognition as foreign. While this process is now well understood in humans, pregnancies in the animal kingdom still provoke many unanswered questions. An international team under the leadership of the GEOMAR Helmholtz Centre for Ocean […]

Endangered Australian seahorses are thriving in new habitats that act like underwater hotels. International species may also be saved by trial "seahorse hotels" in Europe, the United States and Southeast Asia.

A Southern California aquarium has successfully bred the rare weedy sea dragon, the lesser known cousin of the sea horse that resembles seaweed when floating.
