Bamboo sharks and carpet sharks are the common names for the members of the Hemiscylliidae family. The family members are distinguished by having a lizard like shape body, two similarly shaped dorsal fins, long precaudal tail and very large spiracles located behind and below their eyes. Their second dorsal fin is about as large as the first dorsal fin and of similar shape. Their anal fin is moderately large, very low, broad and rounded, with its origin well behind the second dorsal-fin base and its base separated by a notch from the caudal fin.
Members of the Hemiscylliidae are found in the tropical inshore waters of the Indian and western Pacific waters. They are slow-swimming bottom-dwellers, confined to continental waters and continental islands. They feed on invertebrates and small fishes. These sharks are harmless to people.
There are 2 genera and 17 species worldwide. Malaysia has 2 genera and about 6 species.
