Poroderma africanum, commonly known as the puffadder shyshark, is a small, nocturnal shark species native to the coastal waters of South Africa. It has a distinctive pattern of dark saddle markings on its body, thrives in rocky reef habitats, and is known for its unique behavior of curling into a ring when threatened.

Poroderma africanum, commonly known as the puffadder shyshark, is endemic to the coastal waters of southern Africa. Its geographical distribution is primarily along the southwestern coast of South Africa, extending from Namibia to the Eastern Cape region.

The puffadder shyshark inhabits temperate coastal waters, typically found at depths ranging from 0 to 130 meters. It prefers rocky and sandy bottoms, often near kelp forests or reefs, where it can find shelter and prey.

This species occupies a benthic ecological niche, meaning it lives on or near the sea floor. It is well adapted to its environment, using its coloration and patterning to camouflage among rocks and seaweed. The puffadder shyshark feeds on small fish, crustaceans, and mollusks, playing a role in controlling these populations and maintaining the health of its marine ecosystem.
