Description

The Knysna seahorse is a seahorse (Syngnathidae) from a few estuaries on the south coast of South Africa. The species grows to about 12 cm and has an upright body armoured in bony rings with a horse-like head, a prehensile tail and a tubular snout. Due to its very restricted range in only a few estuaries the species is endangered. It swims slowly and clings with its tail to weed, coral or seagrass and sucks in minute crustaceans. The male carries the eggs in a pouch. The fish is harmless to humans.
