The lemon shark, Negaprion brevirostris, shark in the family Carcharhinidae, can grow to 10 feet (3.0 m) long. It is known as the lemon shark because light interacting at certain depths with the local seawater can give this shark a tanned and yellow, pitted appearance, much like the surface of a lemon.
This stocky, powerful shark is named for its pale yellow-brown to grey skin, which lacks any distinctive markings. This provides perfect camouflage when swimming over the sandy seafloor in its coastal habitat. It has a flattened head with a short, broad snout, and the second dorsal fin is almost as large as the first.
The lemon shark is found mainly along the subtropical and tropical parts of the Atlantic and Pacific coasts of North and South America, and around Pacific islands. The longest lemon shark recorded was 13 ft (4.0 m) long, but they are usually 8–10 ft (2.4–3.0 m). They inhabit mostly tropical waters, stay at moderate depths, and are often accompanied by remoras.
Lemon sharks are viviparous, females giving birth to between four and 17 young every other year in warm and shallow lagoons. The young have to fend for themselves from birth, and remain in shallow water near mangroves until they grow larger. With increasing size, they venture further away from their birthplaces. At maturity, at a size of 1.5–2 m and an age of 12–15 years, they leave shallow water and move into deeper waters offshore. However, little is known of this life stage. The maximum recorded length and weight is 340 cm and 183 kg.
