Zebra (Leopard) Shark

Stegostoma fasciatum

Description:

There can be some confusion with the name of this specie as the official name is Zebra Shark but they look more like a Leopard with the brown body and spots on their body. However, this confusion is due to the Juvenile phase of the specie, where they will look more like a Zebra with black stripes instead of spots. The zebra shark (Stegostoma fasciatum) is a species of carpet shark and the sole member of the family Stegostomatidae. It is found throughout the tropical Indo-Pacific, frequenting coral reefs and sandy flats to a depth of 62 m (210 ft). Adult zebra sharks are distinctive in appearance, with five longitudinal ridges on a cylindrical body, a low caudal fin comprising nearly half the total length, and a pattern of dark spots on a pale background. Young zebra sharks under 50–90 cm (20–35 in) long have a completely different pattern, consisting of light vertical stripes on a brown background, and lack the ridges. This species attains a length of 2.5 m (8.2 ft). Zebra sharks are nocturnal and spend most of the day resting motionless on the sea floor. At night, they actively hunt for molluscs, crustaceans, small bony fishes, and possibly sea snakes inside holes and crevices in the reef. Though solitary for most of the year, they form large seasonal aggregations. The zebra shark is oviparous: females produce several dozen large egg capsules, which they anchor to underwater structures via adhesive tendrils. Innocuous to humans and hardy in captivity, zebra sharks are popular subjects of ecotourism dives and public aquaria. The World Conservation Union has assessed this species as Vulnerable worldwide, as it is taken by commercial fisheries across most of its range (except off Australia) for meat, fins, and liver oil. There is evidence that its numbers are dwindling.

Habitat:

The zebra shark occurs in the tropical waters of the Indo-Pacific region, from South Africa to the Red Sea and the Persian Gulf (including Madagascar and the Maldives), to India and Southeast Asia (including Indonesia, the Philippines, and Palau), northward to Taiwan and Japan, eastward to New Caledonia and Tonga, and southward to northern Australia. Bottom-dwelling in nature, the zebra shark is found from the intertidal zone to a depth of 62 m (210 ft) over the continental and insular shelves. Adults and large juveniles frequent coral reefs, rubble, and sandy areas. There are unsubstantiated reports of this species from fresh water in the Philippines. Zebra sharks sometimes cross oceanic waters to reach isolated seamounts. Movements of up to 140 km (87 mi) have been recorded for individual sharks. However, genetic data indicates that there is little exchange between populations of zebra sharks, even if their ranges are contiguous

Thanks, @Lauren.
They don't have the look often associated with 'Sharks' and they are quite harmless although big, up to 2.5 meters in length. Also, they have brownish skin unlike most sharks, that are greyish in color.
They also have very long tails that is very elegant when they swim.

Lovely! This was in your movie and I wasn't even sure it was a shark with those weird ridges and small mouth, until it swam away. The tail is also unusual looking.
