Bamboo Shark
Bamboo sharks are found in shallow waters in the Indo-Pacific Ocean. They are small, slow-moving sharks with long tails.
Class: Chondrichthyes
Order: Orectolobiformes
Family: Hemiscylliidae
Genera: Chiloscyllium and Hemiscyllium
Common Names: Bamboo Sharks, Longtail Carpet Sharks, Epaulette Sharks, Cat Sharks
Bamboo sharks are bottom-dwelling sharks. They are slow-moving fish, probing the sea bottom for crustaceans and small fish with the barbels on their snout. Their habitats are shallow tidal pools, coral beds, and rocky areas.
Bamboo sharks are oviparous, meaning they lay eggs that hatch externally.
They are one of the few vertebrate animal species known to be capable of parthenogenesis, where a female’s egg is fertilized without coming in contact with a male. It was observed in a captive shark in 2016.
Bamboo sharks are small in size, usually less than four feet in length, with slender bodies and long tails. Their tail can sometimes be as long or longer than the entire rest of the shark’s body. Their snouts have feelers called “barbels” underneath that help them find food in their shallow water habitat. These barbels are what earned them one of their common names – the catshark.
Bamboo shark juveniles are often banded in coloration, with thick dark stripes down their body. As they grow older, these bands fade, and different species display different patterning and coloration including spots and large blotches.
There are two genera of bamboo shark, with 16 described species (and one currently not yet described). The genus Chiloscyllium is often referred to as bamboo sharks, while the genus Hemiscyllium are sometimes called epaulette sharks, due to the splotches on the sides of their bodies that resemble the decorative shoulder coverings on military uniforms.
Bamboo sharks are carpet sharks of the order Orectolobiformes. This order includes other sharks that spend much of their time near the sea bottom, such as nurse sharks and zebra sharks.
The largest carpet shark is the whale shark, which is the largest living species of fish. Unlike most other carpet sharks, it is not a bottom feeder but rather a filter feeder.
Most species of bamboo shark range from Near Threatened to Endangered, though a couple are considered Least Concern. Threats to them include pollution and habitat loss. Populations can also be harmed due to overcollection of sharks for aquariums.
Bamboo sharks are a common sight in public aquariums and are popular in private home aquariums. They adapt well to captivity due to their sluggish nature, small size and natural habitat of shallow water and confined spaces. However, as with most shark species, they can be difficult to care for, and require a high level of experience and responsibility to ensure they do well.
