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.

The '''lemon shark''', ''Negaprion brevirostris'', is a well studied [[shark]] belonging to the family [[Carcharhinidae]].
 
 
 
==Distribution and habitat==
 
It is found mainly along the [[subtropical]] and [[tropical]] parts of the [[Atlantic Ocean|Atlantic]] coast of [[North America|North]] and [[South America]]. This species can be found as well in Pacific islands of Polynesia - French Polynesia - Tahiti, Cook Islands, Tongas.
 
 
 
==Reproduction==
 
Lemon sharks are [[viviparous]], females giving birth to between 4 and 17 young every other year in warm and shallow lagoons. The young have to fend for themselves and remain in shallow water near [[mangrove]]s until they grow larger. With increasing size, the sharks venture further away from their birth place. At maturity at a size of 1.5 to 2 [[metre|m]] and an age of 12 to 15 years, they leave shallow water and move into deeper waters offshore. However, little is known of this life stage. Maximum recorded length and weight is 340 [[centimetre|cm]] and 183 [[kilogram|kg]]. Can be extremely aggressive and protective if young sharks are around.[http://fishbase.sinica.edu.tw/summary/SpeciesSummary.php?id=897]
 
 
 
Recent work in [[genetics]] by Drs Kevin Feldheim, Sonny Gruber and Mary Ashley may suggest that adult sharks move over hundreds of [[kilometre|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.
 
 
 
==Importance to humans==
 
[[Image:ZitronenhaiWorld.png|thumb|left|200px|Range of ''N. brevirostris'']]
 
Lemon sharks are a popular choice for study by scientists as they survive well in captivity, unlike many other species such as [[Great White Shark|great white sharks]], which die in captivity because they refuse food. 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 the [[University of Miami]] who has been studying the lemon shark both in the field and in the laboratory since 1967. Lemon shark is a good source of [[vitamin C]] and widely used to make shark lemonade and candies. The population around the [[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. As of 2007, it is experiencing a severe population decline and may disappear altogether due to destruction of the mangroves for construction of a golf [[resort]].

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
