Fun Facts:

  • Seahorses are found in temperate and tropical waters all over the world, including the Hudson River
  • The male seahorse receives eggs from the female and keeps them in a pouch where he fertilizes and carries them until they are ready to hatch
  • Seahorses can easily die of exhaustion in stormy weather; they are not strong swimmers and rely on their prehensile tail to anchor themselves to vegetation and substrata
  • The serial, bony rings that make up their secondary, dermal skeleton are quadrilateral – one of the only instances of square biological components in animals
