Hemiscyllium
''Hemiscyllium'' is a genus of sharks in the family Hemiscylliidae. Overview This genus is confined to tropical waters off Australia, Papua New Guinea, and Indonesia, but an individual from this genus, possibly representing an undescribed species, has been photographed at the Seychelles. They have short snouts with the nostrils placed almost at the tip, and well-elevated eyes and supraorbital ridges. The mouth is closer to the tip of the snout than the eyes, and lacks the connecting dermal fold across the chin. The pectoral and pelvic fins are thick and heavily muscular. Either a black hood on the head or a large black spot on the sides of the body is present, though juveniles often are strongly marked with dark spots/bars. Some species are known as "walking sharks". In January 2020, marine biologists at the School of Biomedical Sciences at the University of Queensland in Australia announced new findings that provide evidence that genus ''Hemiscyllium'', also known as "walking ...

Hemiscyllium Ocellatum
The epaulette shark (''Hemiscyllium ocellatum'') is a species of longtailed carpet shark, family Hemiscylliidae, found in shallow, tropical waters off Australia and New Guinea (and possibly elsewhere). The common name of this shark comes from the very large, white-margined black spot behind each pectoral fin, which are reminiscent of military epaulettes. A small species usually under long, the epaulette shark has a slender body with a short head and broad, paddle-shaped paired fins. The caudal peduncle (to which the tail fin is attached) comprises over half the shark's length. Adults are light brown above, with scattered darker spots and indistinct saddles. Epaulette sharks have nocturnal habits and frequent shallow water on coral reefs or in tidal pools. This shark has evolved to cope with the severe night time oxygen depletion (hypoxia) in isolated tidal pools by increasing the blood supply to its brain and selectively shutting down non-essential neural functions. It is cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemiscylliidae
The Hemiscylliidae are a family of sharks in the order Orectolobiformes, commonly known as longtail carpet sharks and sometimes as bamboo sharks. They are found in shallow waters of the tropical Indo-Pacific. They are relatively small sharks, with the largest species reaching no more than in adult body length. They have elongated, cylindrical bodies, with short barbels and large spiracles. As their common name suggests, they have unusually long tails, which exceed the length of the rest of their bodies. They are sluggish fish, feeding on bottom-dwelling invertebrates and smaller fish. Genera and species ''Chiloscyllium'' This genus is distinguished by a relatively long snout with subterminal nostrils. The eyes and supraorbital ridges are hardly elevated. The mouth is closer to the eyes than to the tip of the snout, with lower labial folds usually connected across the chin by a flap of skin. The pectoral and pelvic fins are thin and not very muscular. No black hood on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiscyllium Henryi
The Triton epaulette shark (''Hemiscyllium henryi'') is a species of bamboo shark in the genus ''Hemiscyllium'', that is composed of nine morphologically similar, yet distinct sharks that are geographically restricted to New Guinea and northern Australia. Hemiscylliidae are small nocturnal sharks aptly named "walking sharks" who exhibit a "crawling" movement while foraging on the ocean floor for fish and benthic invertebrates.Allen, G.R., Erdmann, M.V., White, W.T., Fahmi & Dudgeon, C.L. (2016) Review of the bamboo shark genus Hemiscyllium (Orectolobiformes: Hemiscyllidae). Journal of the Ocean Science Foundation, 23, 51–97. Morphology These small slender sharks are characterized by nasoral and perioral grooves, short barbels, a small transverse mouth below the eyes, two similar-sized dorsal fins and long slender tail. They are typically pale gray-brown with a white ventral surface. Individuals of the genus ''Hemiscyllium henryi'' are distinguished by their unique colour patter ...

Hemiscyllium Halmahera
''Hemiscyllium halmahera'', or the Halmahera epaulette shark, is a species of bamboo shark from Indonesia. This species is described from two specimens collected near Ternate island in 2013, off the coast of larger Halmahera island. This species is most similar to '' Hemiscyllium galei'', found in West Papua, but looks strikingly different in its pattern of spots. While ''H. galei'' has seven large, dark spots on each side of its body, ''H. halmahera'' has a brown color with clusters of brown or white spots in polygon configurations all over its body. These small sharks are like other bamboo sharks, in that they use their pectoral fins Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as se ... to "walk" along the ocean floor.

Hemiscyllium Freycineti
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.Michael, S. (May 16, 2008). Will the real Hemiscyllium freycineti please stand up?' 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''. Confusingly, some books with illustrations and photos labelled as ''H. freycineti'' actually show ''H. michaeli''. ''H. freycineti'' rea ...

Hemiscyllium Galei
''Hemiscyllium galei'', the Cenderawasih epaulette shark, is a species of bamboo shark in the family Hemiscylliidae. Together with '' H. henryi'', it was only scientifically described in 2008 by Gerald R. Allen and Mark V. Erdmann. At present, ''H. galei'' is only known from depths of at reefs in the Cenderawasih Bay in West Papua, Indonesia. The largest known specimen was long. It can be separated from its relatives (e.g., '' H. freycineti'') by the combination of seven relatively large dark spots along the side of the body (between the abdomen The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates.
