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. The first dorsal fin includes a mildly venomous spine, used in defense. Long-nosed chimaeras are found in temperate and tropical seas worldwide, from 200 to 2000 m in depth. In August 2020, a long-nosed chimaera was brought up from 460 fathom off the Grand Banks of Newfoundland. They range from 60 to 140 cm in maximum total length, depending on species.
