Other forms: seahorses

A seahorse is a small upright fish whose males carry the eggs. A tiny seahorse, seahorses in the weed, the seahorse's tail.

The male carries the eggs in a pouch and gives birth, which is genuinely unique among animals. It swims upright and badly, and it holds onto weed with its tail because it cannot fight a current.
