binomial_authority = Marini, 1936The angular angel shark, "Squatina guggenheim", is an angel shark of the family Squatinidae found off southern Brazil and Argentina at depths of between 4 and 265 m. Its length is up to 1.3 m.

The angular angel shark is found on the outer continental shelf. The head is concave between the eyes, and the pectoral fins are relatively large, high, and angular, with a nearly-straight leading edge and concave trailing edge. There are short strong thorns in symmetrical groups on the snout and between the eyes. The nasal barbels have cylindrical bases, with expanded, slightly spatulate, unfringed tips. The anterior nasal flaps are barely fringed. They eat bony fishes, and crustaceans and molluscs.

Coloration is a uniform dark tan with numerous small yellowish spots and larger blackish marks. There are a few ocelli on the pectoral fins.

Reproduction is ovoviviparous, with 6 to 8 pups in a litter.

It was formerly named "Squatina occulta".
