About this species

Seahorses cling to seagrass and gorgonians with their prehensile tails, swaying with the current to look like just another piece of vegetation. They feed on tiny crustaceans and are surprisingly small — most Red Sea seahorses are 8-12 cm. Males brood the eggs in a belly pouch and 'give birth' to up to 2,000 babies.

Fun facts

  • Males get pregnant — the only animal where this is true
  • Mate for life
  • Have no stomach — must eat constantly
  • Eyes move independently like a chameleon
