Description

White's seahorse is a seahorse from coastal and estuarine water of eastern Australia, around Sydney. The species grows to about 13 cm and has an upright, bony-ringed body, a horse-like head and a prehensile tail with which it clings to seagrass, sponges and artificial structures. With its tubular snout it sucks up minute crustaceans. The male broods the eggs in a pouch. Owing to habitat loss the species has declined sharply. The IUCN assesses it as Endangered (EN).
