Description

Retzius's freshwater pipefish is a pipefish (Syngnathidae) from the Indo-West Pacific, unusual in living largely in fresh water. The species has a very slender, bony-ringed armoured body and a tubular snout. It inhabits clear streams and rivers, sometimes far inland. With its tubular snout it sucks up small zooplankton and small invertebrates. Like all pipefishes the male carries the eggs, here on the underside of the body. The species is harmless to humans.
