Predators of the leopard catshark include larger sharks and marine mammals; it is one of the cartilaginous fish most often consumed by the broadnose sevengill shark (Notorynchus cepedianus). [14] [15] When threatened, it curls into a ring with its tail covering its head, a behavior also performed by the shysharks (Haploblepharus). [16]
The finback catsharks are a small family, the Proscylliidae, of ground sharks. [1] They can be found in warm seas worldwide and are often the most numerous and common shark in tropical regions. They are generally less than 1 m in length, and are slow-moving predators that feed on bony fish and small invertebrates.
Scyliorhinidae catsharks may be distinguished by their elongated, cat-like eyes and two small dorsal fins set far back. Most species are fairly small, growing no longer than 80 cm (31 in); a few, such as the nursehound (Scyliorhinus stellaris) can reach 1.6 m (5.2 ft) in length.
A known predator of this species is the southern African frilled shark (Chlamydoselachus africana). [6] Unlike other members of its genus, the African sawtail catshark is aplacental viviparous, with females retaining eggs internally until they hatch. There is apparently no defined breeding season, and mating and birthing occur throughout the year.
Haploblepharus is a genus of deepwater catsharks, belonging to the family Pentanchidae, containing four species of shysharks. Their common name comes from a distinctive defensive behavior in which the shark curls into a circle and covers its eyes with its tail. The genus is endemic to southern Africa, inhabiting shallow coastal waters. All four ...

[4] Its diet is dominated by bony fishes and crustaceans, and also includes cephalopods, polychaete worms, smaller sharks, and scavenged fish offal.
