pyjama shark

5/23/2018

Contrary to their common name, pyjama sharks (Poroderma africanum) do not stay in their pj's... but boy, don't we wish. With unmistakable stripes running down the length of their bodies, and two dorsal fins that are at the waaaay back, these cuties are one-of-a-kind.
Reaching a maximum length of 3.1 feet (95 cm), they can be observed from the continental shelf to the upper slope down to 282 metres (925.2 ft) deep. Usually on or near the bottom in rocky areas, they can be seen in caves either resting (they are often nocturnal) or putting those short nasal barbels to use and sniffing out prey. What do they eat? A variety of fish, small sharks, shark eggcases, hagfish (slimy!!) and a range of invertebrates.

Found in the southeast Atlantic and western Indian Oceans, they are endemic to South Africa (both Capes, rarely found in KwaZulu-Natal). An oviparous species, they lay a pair of eggcases. Also known as the "Striped Catshark," the IUCN has assessed them as Near Threatened (NT) due to pressure from commercial and sports fisheries.

WHAT DID YOU LEARN THAT'S NEW?

GLOSSARY

  • Commercial fishery: The activity of catching fish and other seafood for profit.
  • Continental shelf: Extends from a continent underwater, resulting in a shallow-water area.
  • Continental slope: The steep slope from a continental shelf to the ocean floor; usually around 20 km (12.4 miles) wide and made up of mud and silt substrate. It is an ideal area for deep sea fishing.
  • Invertebrates: Animals with no backbone (i.e. crustaceans, jellyfish, corals, sea anemones).
  • IUCN: International Union for Conservation of Nature.
  • Nocturnal: Active at night.
  • Near Threatened: May be considered threatened with extinction in the near future, although it does not currently qualify for the threatened status.​
  • Oviparity/oviparous: Where adult Chondrichthyans lay eggcases (also known as ‘mermaid’s purses) and the baby develops inside the egg before hatching.
  • Pup: Give birth to baby sharks (pups).​
  • Pups: Baby sharks.
