TheRhinochimaeridae, commonly known aslong-nosed chimaeras,[1] are afamily ofcartilaginous fish. They are similar in form and habits to otherchimaeras, but have an exceptionally long conical or paddle-shaped snout.[2] The snout has numerous sensory nerve endings, and is used to find food such as small fish.[3] The firstdorsal fin includes a mildly venomous spine, used in defense.[4]
Long-nosed chimaeras are found in temperate and tropical seas worldwide, from 200 to 2,000 m (660 to 6,560 ft) in depth.[4] In August 2020, a long-nosed chimaera was brought up from 460 fathoms (2,760 ft; 840 m) off theGrand Banks of Newfoundland.[5]
They range from 60 to 140 cm (2.0 to 4.6 ft) in maximum total length, depending on species.
The eight known species are in three genera:[4]
