Squalomorphi[1] is a superorder of cartilaginous fishes, generally characterized by lacking traits such as an anal fin, nictitating membrane, or suborbital shelves in the cranium.

Squalean sharks are divided into five orders: the Echinorhiniformes, Hexanchiformes, Squaliformes, Squatiniformes, and Pristiophoriformes.

Squaliform sharks are extremely variable in size and shape, and can be found in most marine habitats throughout the world.

The angel sharks have flattened bodies and broad pectoral fins, as well as camouflaged coloration.

Sawsharks have a long snout covered in teeth, between 5-6 gill slits, and no anal fin.
