An international team led by researchers from IRTA at the IBB-UAB and the University of Bergen have identified a unique set of genes that allows marine teleost fishes to hydrate their eggs so that they float and disperse for survival in the ocean. The discovered mechanisms shed new light on the evolution of this group of fishes, to which almost all modern marine fishes belong and whose ancestors ventured from freshwater to the saline domain.
