The Necklace Carpetshark or Varied Carpetshark (Parascyllium variolatum) is also known as Southern Catshark, Varied Catshark or Ring-necked Catshark – even if it’s not a species of catsharks but collared carpet sharks (which is a species of the order carpet sharks, just like for instance the whale shark and the distantly related wobbegongs). That many names suggest that it is an widely common species, but Necklace carpetsharks live solely off South-Australia.

Necklace carpetsharks are slender with oval eyes; they are oviparous (that means they lay eggs) and resemble in that aspects catsharks. Their light or dark brown body has got white dots and an eponymous, distinct black band with small white spots on their neck.

Necklace carpetsharks live in temperate waters along the continental shelf at depths up to 590 ft -180 m- over sand, rocky reefs, kelp or seagrass beds. They are nocturnal and hide under rocks during daylight hours.

With up to 36 in -91 cm- length, the pretty Necklace carpetshark is sometimes shown in public aquaria.
