The spotted swellshark (Cephaloscyllium maculatum) is a species of catshark, family Scyliorhinidae, known only from a single 18.8 cm (7.4 in) long juvenile specimen caught off eastern Taiwan. It is a fairly slender shark with a short, flattened head and a relatively small mouth, and is characterized by its color pattern of angular hollow saddles and lateral blotches on a brownish background. Like other swellsharks, this species has a greatly expandable stomach.
