The body of a seahorse is highly compressed, covered in hard, bony plates. Its dorsal fin is located low on its back and is propelled for movement. They have long snouts and long tails which are used for grip, and their ventral edge is sharp. Pygmy seahorses grow only up to 5 cm. They differ in colour from black to bright yellow and can be spotted in pink or green.
