The Pyjama Shark, Striped Catshark, scientifically known as Poroderma africanum, is a fascinating species of catshark inhabiting the coastal waters of the southern African region. This shark is characterized by its distinctive striped pattern, which resembles pajamas, hence its common name.
Description & Characteristics
Poroderma africanum can reach a maximum size of 101.0 cm, displaying a slender, elongated body shape typical of catsharks. Their dorsal fins are positioned close together, with the second dorsal fin being significantly smaller than the first. The distinctive feature of this shark lies in its coloration, which is characterized by numerous dark brown to black stripes that run vertically across its body, resembling the pattern of pajamas. These stripes are particularly prominent on the back and sides of the shark, contrasting with the lighter, grey-brown background color. This striking coloration serves as camouflage, allowing the shark to blend seamlessly into its surroundings, particularly in the rocky reefs and kelp forests it calls home.
Habitat and Occurrence
Poroderma africanum is commonly found in the coastal waters of South Africa, ranging from Namibia to the Eastern Cape. These sharks are predominantly found in the neritic zone, inhabiting depths ranging from the surface down to 100.0 meters. This species prefers rocky reefs and kelp forests, where they can find shelter amongst the complex structures and abundant food sources. Poroderma africanum is often found near the bottom, utilizing its agile and slender body to maneuver effectively through the intricate crevices and rocky outcroppings of its habitat.
Taxonomy
Poroderma africanum belongs to the Class: Elasmobranchii, Order: Carcharhiniformes, and Family: Scyliorhinidae, a family known for its diverse array of catsharks. The genus Poroderma encompasses several other catshark species, each possessing unique characteristics and inhabiting specific regions of the world.
Feeding
Poroderma africanum is a carnivorous species, feeding on a diverse range of prey that inhabit their rocky reef and kelp forest habitats. They are opportunistic feeders, readily consuming crustaceans, such as crabs, lobsters, shrimps, and krill, as well as mollusks like clams. Additionally, they prey on various small fish, including coralfish, often foraging at night when their prey is less active. Their slender body shape allows them to effectively navigate the intricate structure of their preferred habitat, utilizing their powerful jaws and sharp teeth to subdue and consume prey.
