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

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

They resemble other chimaeras in general form and habits, but have a short, rounded, snout, without the modifications found in related families. Many species have a long tapering tail, given 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. Most species are restricted to depths below 200 metres (660 ft), but a few, notably the spotted ratfish, can locally be found at relatively shallow depths. They range from 38 centimetres (15 in) to 150 centimetres (4.9 ft) in maximum total length, depending on species.[1]

Species

The 36 species are grouped into two genera:[1]

Family Chimaeridae
