The '''lemon shark''' (''Negaprion brevirostris'') is a well studied [[shark]] belonging to the family [[Carcharhinidae]]. It is found mainly along the subtropical and tropical part of the [[Atlantic Ocean|Atlantic]] coast of N and S America. The species is the best known of all sharks in terms of behaviour and ecology, mainly thanks to the enormous effort of Dr. Samuel Gruber at [[University of Miami]] who has been studying lemon shark both in the field and in the laboratory for the past 40 years. The population around [[Bimini Islands]] in the western Bahamas, where Dr Gruber's field station Bimini Biological Field Station is situated, is probably the best known of all shark populations. It is currently experiencing a severe population decline and may disappear altogether due to destruction of the [[mangrove]]s for construction of a golf [[resort]].

Female lemon sharks give birth to 4-17 young every other year in warm and shallow lagoons. The young have to fend for themselves and remain in shallow water near mangroves until they grow bigger. With increasing size, the sharks venture further away from their birth place. At maturity at a size of 1.5-2 m and an age of 12-15 years, they leave the shallow water and move into deeper waters more offshore. However, little is known from this life stage. Maximum recorded length and weight is 183 Kg and 340 cm.[http://fishbase.sinica.edu.tw/summary/SpeciesSummary.php?id=897]

Recent [[genetics|genetic]]al work by Drs Kevin Feldheim, Sonny Gruber and Mary Ashley may suggest that adult sharks move over hundreds of km to mate, or populations far apart may have been separated in recent time. Further research in this area would be of immense importance for the understanding of the lemon shark's breeding behaviour and ecology.

Lemon sharks are a popular choice for study by scientists as they get on quite well in captivity, unlike many other species such as [[Great_White_Shark|great whites]], who die in captivity because they refuse food.

Negaprion brevirostris

Lemon Shark (Negaprion brevirostris)

Where found: 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. They inhabit mostly tropical waters, stay at moderate depths, and are often accompanied by remoras.

Description: The lemon shark commonly attains a length of 2.4 to 3.1 meters and a weight of up to 90kg at adulthood. The maximum recorded length and weight is 3.43m and 183.7kg. This stocky, powerful shark is named for the 'citrus glands' located between its two dorsal fins. This gland allows the shark to exude a lemon-esque scent in order to attract its prey. The lemon shark has 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. Good video on Lemon and Tiger Sharks
