Pipehorses are small fishes with slender and elongate bodies (3). Unlike many other fish, their bodies have no internal bones or external scales, and are instead encased in a series of hard, spiny rings (3) (4). The largest member of the Syngnathidae family occurring in Australia (5), the spiny pipehorse has a long and tubular snout, with a small, toothless mouth situated at the tip (3). It may be yellow, pink or orange in colour, patterned with narrow yellow bars and variable dark bars and blotches, and the area around the anus is red-brown (5). The tail is prehensile (5), enabling it to grasp to corals, sponges and other structures on the ocean floor (6).
Although little information is available regarding the specific biology of the spiny pipehorse, most pipehorses are known to feed on minute animals living on the ocean bottom or within the water, such as tiny crustaceans (3).
All pipehorses also have a remarkable and unique method of reproduction (3). During the breeding period, the tail of the male becomes brightly coloured and spongy (6). The female deposits eggs on to the underside of the male’s tail (3) (5), where they are fertilized. The male then holds the responsibility of incubating the precious brood until they hatch (3).
TopThe spiny pipehorse occurs in the southwest Pacific Ocean, around southern Australia and New Zealand (2).
See this species on Google Earth.
TopLiving in temperate marine waters (5), the spiny pipehorse occurs down to depths of 230 metres (2), where it is often found over muddy bottoms (5). Pipehorses are often found around corals, algae or sponges, holding onto these structures with their tails (6).
TopClassified as Data Deficient (DD) on the IUCN Red List (1).
TopAlthough pipehorses are not specifically targeted by fishermen, they are often captured as bycatch (6), which threatens their existence. Once caught, they may be dried and used in traditional Chinese medicine, in which they are a highly valuable ingredient, sold as curios, or traded live as aquarium fish (6).
TopAll species within the Syngnathidae family are protected in New South Wales, Australia, under the NSW Fisheries Management Act 1994, meaning the collection, harvest or possession of any species of pipehorse in New South Wales is prohibited without a permit (4).
