Teleost fish, which roughly make up half of the extant vertebrate species, exhibit an amazing level of biodiversity affecting their morphology, ecology and behaviour as well as many other aspects of ...

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 ...
