Range of the Indonesian speckled carpetshark (note: It is only found in the far western part of the blue) |
The Indonesian speckled carpetshark, Hemiscyllium freycineti, is a species of bamboo shark in the family Hemiscylliidae. It is found in the shallow ocean around the Raja Ampat Islands in West Papua, Indonesia, but was formerly believed to be more widespread. This was due to confusion with H. michaeli, a species described from eastern Papua New Guinea in 2010.[1][2] Compared to that species, the spots on H. freycineti are smaller, more rounded or slightly elongated in shape (versus relatively large, edged and more leopard-like in H. michaeli), and tend to darken at regular intervals forming 8-9 vertical bars on the body and tail. Furthermore, the large black spot behind the pectoral fin is more clearly defined in H. michaeli than in H. freycineti.[1][2] Confusingly, some books with illustrations and photos labelled as H. freycineti actually show H. michaeli.[1][2]
H. freycineti reaches a length is up to 46 centimetres (18 in).[3] It is nocturnal, hiding in reef crevices during the day.[4]

You won’t find them in your carpet or your bamboo flooring, but they do walk! Have no idea what I'm talking about? You will! I'm Jonathan Bird and this is Shark Academy! The family of small bottom-dwelling sharks known as "Longtail Carpet Sharks" consists of two distinct genera, commonly known as the Bamboo sharks and the Epaulette sharks. Bamboo sharks often have banded coloration that makes them look a little bit like Bamboo, especially in the juvenile phase. Epaulette sharks are named for the large dark spot that looks like a military Epaulette—you know that thing on the shoulder of a military uniform! One of the more famous Epaulette sharks is the Indonesian Speckled Carpetshark, which is also known as the “walking shark,” because it often walks along the bottom using its pectoral fins like legs! Both the Bamboo sharks and the Epaulette sharks are small and harmless, living on the bottom and eating invertebrates like crabs and worms. They are popular in large home aquaria because they don't need a lot of space like most sharks. They can also survive in very low oxygen environments if they have to, so they do well in mangroves and fish tanks that the filter is busted. If you’re interested in sharks, don’t go away! There are more than 30 Shark Academy episodes to watch! You can also join my underwater adventures on Jonathan Bird’s Blue World! And don’t ever miss a new episode, subscribe now!
Etymology
The shark is named in honor of French navigator Louis de Freycinet (1779-1841), who collected the type specimen.[5]
