Male seahorses transport nutrients to embryos


Researchers have discovered male seahorses transport nutrients to their developing embryos in their brood pouch. The next step is to find out how they do this and if they have a placenta.

New research by Dr Camilla Whittington and her team at the University of Sydney has found male seahorses transport nutrients to their developing babies during pregnancy. This discovery provides an opportunity for further comparative evolutionary research.

Seahorses and their relatives are the only vertebrates that have male pregnancy. The expectant fathers incubate developing babies inside a pocket called a “brood pouch”. We know a male seahorse can have more than a thousand embryos in the pouch at once but until now, researchers had limited understanding of how the babies are fed. MORE
