Although it's well known that seahorses and their cousins the pipefish are the only vertebrates where males become pregnant, researchers have only begun to understand how this unique adaptation works. By studying the behavior of these charismatic fishes and sampling the RNA within the male's pouch, biologist Tony Wilson and his lab at Brooklyn College have found that seahorse pregnancy may have a deeper genetic link to other forms of pregnancy than previously thought.
