Also known as “carpet sharks” or “cat sharks,” bamboo sharks live in shallow waters and coral reefs in the Indo-Pacific region. Bamboo sharks are slow bottom-feeders that prey on crustaceans, mollusks, and small fish. Due to their small size, they are often found in home and commercial aquariums. However, the IUCN lists them as threatened due to over-harvesting and habitat loss.

Under the right circumstances, bamboo sharks can live up to 25 years, although most specimens will not live this long.

Classification and Scientific Name

Bamboo sharks belong to the order Orectolobiformes. Members of this order often go by the name carpet sharks due to their intricate patterns, which resemble the designs on ornate carpets. They belong to the family Hemiscyllidae. The word Hemiscyllidae derives from the Greek words hemi, meaning “half,” and skylla, meaning “a type of shark.” Roughly translated, the name means “half of a shark,” due to its half-shark, half-fish appearance. The family consists of two genera, Chiloscyllium and Hemiscyllium, but only those in Chiloscyllium typically go by the name bamboo shark.

The common name “bamboo shark” stems from its long, slender appearance. The term “longtail carpet shark” refers to their exceptionally long tails that measure longer than the rest of their bodies. Meanwhile, the name “cat shark” refers to the barbells near their mouths, which resemble cat whiskers. 

Appearance

You can find bamboo sharks throughout the Indo-Pacific region.

Generally speaking, bamboo sharks have relatively long snouts and subterminal nostrils. Like all members of Orectolobiformes, they feature five gills, two spineless dorsal fins, and a small mouth. The mouth is positioned close to the eyes, which lie flat along the head. They feature thin, non-muscular pelvic and pectoral fins, hence their rather sluggish rate of movement. The body appears tubular, and the tail takes up at least half or more of the total body length. 

Predators and Prey

Due to their relatively small size, several animals likely prey on bamboo sharks. These include large fish as well as other sharks. 

Bamboo sharks are bottom-feeders and feed mostly at night, preying on small fish, crustaceans, and mollusks. They rely on electroreceptors in their snouts to help them find prey hiding in sand and mud. Their preferred prey includes fish, shrimp, scallops, and crabs. They use their rows of up to 67 tiny teeth to grab and hold onto their prey. Some species possess unique adaptations for feeding on tougher prey. For instance, brownbanded bamboo sharks can reel their teeth backward. This allows them to expose the front surface of their teeth and turn them into a plate for crushing the tough shells of crustaceans. 

Reproduction and Lifespan

Female bamboo sharks lay a clutch of several eggs in a nest of sandy substrate. The eggs take between 14 and 15 weeks to develop, during which time the embryos feed on the yolk within the egg case. Some evidence suggests they can breed parthenogenetically, meaning they can reproduce asexually.  

Under the right conditions, bamboo sharks can live for nearly 25 years. However, most specimens likely do not live this long in the wild. 

Population

While exact population numbers are not well-known, what is known is that they are quite rare. In the wild, all species face significant threats from overfishing and habit loss. They are caught both as a by-product of commercial fishing and by recreational anglers. Some species, such as the whitespotted bamboo shark and brownbanded bamboo shark, are sometimes kept as pets in aquariums due to their small size and relatively docile, sedentary nature. However, others, such as the Burmese bamboo shark, go unseen in the wild for years.

Bamboo sharks are relatively small, with the largest members of the species reaching 4 feet in length.

Due to the threats they face in the wild, the IUCN classifies the brownbanded, whitebanded, and Arabian species as Near Threatened. Meanwhile, the slender, grey, and Burmese species are classified as Vulnerable. Finally, the IUCN lists Hasselt’s as an Endangered species.
