The Chimaeridae, or shortnose chimaeras, are a family of cartilaginous fish.

They resemble other chimaeras in general form and habits, but have short, rounded snouts, without the modifications found in related families. Many species have long, tapering tails, giving them an alternative name of ratfish. Shortnose chimaeras have a venomous spine on their backs, which is sufficiently dangerous to injure humans.[1]

They are found in temperate and tropical marine waters worldwide.[2] Most species are restricted to depths below 200 m (660 ft),[2] but a few, notably the spotted ratfish and rabbit fish, can locally be found at relatively shallow depths. They range from 38 to 150 cm (1.25 to 4.92 ft) in maximum total length, depending on species.[1]

Distribution

provided by World Register of Marine Species
Atlantic, Pacific, and Indian oceans in temperate to tropical waters, mostly below 200 m. Short and rounded snout. First dorsal fin erectile, with a strong spine; second dorsal fin long and low. Diphycercal tail, i.e. vertebral colum runs straight to the tip, dividing the caudal fin symmetrically. Anal fin confluent with caudal fin in Hydrolagus; separate in Chimaera. Feed on small fishes and bottom invertebrates. Males with head clasper. Oviparous; large tadpole-shaped egg capsules are deposited on substrate. Dorsal spine with associated poison gland, the venom of which hurts humans.
