The Rhinochimaeridae, commonly known as long-nosed chimaeras, are a family of cartilaginous fish. They are similar in form and habits to other chimaeras, but have an exceptionally long conical or paddle-shaped snout. The snout has numerous sensory nerve endings, and is used to find food such as small fish.[2] The first dorsal fin includes a mildly venomous spine, used in defense.[1]

Long-nosed chimaeras are found in temperate and tropical seas worldwide, from 200 to 2,000 m (660 to 6,560 ft) in depth.[1] They range from 60 to 140 cm (2.0 to 4.6 ft) in maximum total length, depending on species.
