There are more than 400 known species of sharks on earth, with their existence dating back to about 420 million years ago. Humankind has always been afraid of sharks because of their predatory nature. However, not all species with the designation of shark are as threatening and dangerous. Zebra Sharks fall in this category. The zebra shark, scientifically known as the Stegostoma fasciatum, is quite an intriguing and interesting shark species to know about. It is a species of carpet shark found resting on the sea floor in tropical and coastal waters. As nocturnal bottom-feeders and dwellers, the Zebra Sharks are usually seen resting on the seafloor or calmly cruising over tropical coral reefs during the day. Young zebra sharks sport yellowish stripes, but these change to small black dots as they become adults. Due to the presence of black dots their appearance closely resembles that of a leopard.

Zebra sharks are oviparous organisms; that is the young ones are produced from eggs. Internal reproduction takes place in zebra sharks. Zebra sharks reach maturity when the males grow up to eight feet while the females reach the maximum length of six feet. During zebra shark reproduction, the male zebra shark approaches the female and shows interest by snapping at their tails. The male attaches to the females by grasping the female pectoral fins and they lie together for a given time period on the ocean floor. Eventually, the male zebra shark transfers sperm to the female cloaca by using claspers.
The female zebra sharks can lay up to four eggs at a time. During each mating season, a single female can lay up to 46 eggs in the total time span of about 112 days from which the juvenile zebra shark will hatch. Zebra shark egg case is dark brown to purple in color. Interestingly, there have been some rare instances of zebra shark asexual reproduction as well.

Zebra sharks are listed as endangered species by the IUCN Red List. The IUCN Red List is a critical indicator of the status of the world’s biodiversity, a powerful tool to inform and catalyze the conservation of biodiversity. It is released by the Global environmental union, IUCN. The IUCN, or International Union for Conservation of Nature, is a global environmental organization formed to bring together the governmental and non-governmental agencies, to work in a partnership with the common goal of conservation of nature and natural resources.
The IUCN Red List places the species of the zebra sharks as vulnerable to extinction. The population of zebra sharks is declining largely due to coral reef habitat loss and human activities, such as hunting and overfishing. They are preyed upon for a number of benefits.
