Marine species guide
Seahorse
Seahorses are cryptic pipefish relatives that cling to seagrass and hydroids with a prehensile tail. Patience and perfect buoyancy matter more than depth.
Identification features
Horse-like head, bony rings, and a curled tail are diagnostic. Species differ in snout length, coronet shape and skin filaments. Colour matches habitat—yellow, brown or grey.
- Upright posture and prehensile tail
- Bony body rings
- Cryptic on seagrass or fouling
- Very small swimming movements
Habitat and behaviour
They move slowly by dorsal fin flutter. Do not handle; their armour looks tough but stress and habitat damage are real risks.
Where and when to see them
Lookalikes include pipefish (elongated, no upright posture) and small frogfish in some regions.
Dive tips
