Genera
A Chimaeridae fish and deepwater mussels at edge of a brine pool.

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.[1] Shortnose chimaeras have a venomous spine on their backs, which is sufficiently dangerous to injure humans.[2]

They are found in temperate and tropical marine waters worldwide.[3] Most species are restricted to depths below 200 m (660 ft),[3] 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.[2]
