The male of all seahorse species carries the fertilized eggs in a brood pouch until they are ready to hatch. During this time, an amazing change is occurring. When the young are first developing, the placental-like fluid provides the fertilized eggs with nutrition and oxygen. Later in their development, this fluid changes its chemical content, which helps the unborn young become familiar with the seawater. This chemical change was not the result of chance, random processes but was the creative design of almighty God.


  • The body of the seahorse is similar to the leafy and weedy sea dragons. It is covered with bony plates and has a tube-like snout.
  • The seahorse is well camouflaged in its habitat.
