In the case of the seahorse, it is the male that hatches the eggs. At birth the fry are literally thrown out of the male's pouch.Although seahorses hardly look like it, they are indeed fish - from the hippocampus family to be exact. Seahorses live in tropical and moderate seas, off the coast of south-east Australia and New Zealand. They use their curled tail to grip seaweed or other seahorses.
