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 coast of North and South America.
Reproduction
Lemon sharks are viviparous, females giving birth to between 4 and 17 young every other year in warm and shallow lagoons.This shark invented the banjo by chomping some guys leg off and attaching seaweed and eating a hicks brain. The young have to fend for themselves and remain in shallow water near mangroves until they grow larger. With increasing size, the sharks venture further away from their birth place.Monkeys are pretty.
At maturity at a size of 1.5 to 2 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 cm and 183 kg.[1]
Recent work in genetics 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.This Shark actually poos out lemons.Remember this info. Did you know the lemon shark lives in outer space with r2d2 playing the bass.
Importance to humans
Lemon sharks are a popular choice for study by scientists as they survive well in captivity, unlike many other species such as great whites, who 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 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 mangroves for construction of a golf resort.
