[3], There are five distinctive ridges running along the body in adults, one along the dorsal midline and two on the sides.

Adult zebra sharks have five longitudinal ridges on its cylindrical body, a low caudal fin that comprises nearly half of its total length and dark spots along a pale background. Because of this, zebra sharks are often mistakenly referred to as leopard sharks. [13] Off southeast Queensland, aggregations of several hundred zebra sharks form every summer in shallow water. Squalus pantherinus Kuhl & van Hasselt, 1852 These animals live alone, and spend a majority of the day resting on the bottom. No type specimen was designated, though Seba included a comprehensive description in Latin and an accurate illustration of a juvenile. On occasion this leads to mating, in which the male curls his body around the female and inserts one of his claspers into her cloaca.

Adults can reach a maximum length of 354 cm and live over 28 years in aquariums. Consequently, the former and older is the valid name (as Stegostoma tigrinum), while the latter and younger is its junior synonym. Squalus tigrinus Forster, 1781 Faint remnants of this pattern can often be seen in adult sandy zebra sharks. However, there are a few countries that have some conservation measures in place. The zebra shark adapts well to captivity and is displayed by a number of public aquaria around the world. Their eggs are large, dark brown or purplish black with longitudinal striations. [10], The color pattern in young sharks is dark brown above and light yellow below, with vertical yellow stripes and spots. [3] Goto (2001) placed the zebra shark as the sister group to a clade containing Rhincodon and Ginglymostoma. [2] Due to their different color patterns and body proportions, both juveniles and subadults have historically been described as separate species (Squalus tigrinus and S. longicaudatus respectively).
