You are looking at an unborn catshark aka brown banded bamboo shark (Chiloscyllium punctatum). It is one of the smallest of the catsharks. The Brown Banded Bamboo Shark is a tropical species found across the northern coast of Australia and the Indo-Pacific north to Japan and west to the east coast of India. Its common name comes from the juvenile's pattern of dark chocolate brown bands on a cream body; these blend and fade to a uniform grey or brown in adulthood.

When the young hatch from their eggs they are about 17 cm long but they grow to a metre or more. Their bodies are slender with broad paddle-shaped pectoral fins that are used to wedge themselves into crevices to avoid predators. This shark is often confused with the Nurse or Blind Shark but it can be easily distinguished by the conspicuous white edges to its gills.
