The lemon shark (Negaprion brevirostris) is a stocky and powerful shark named for its yellow color.[2] A member of the family Carcharhinidae, lemon sharks can grow to 10 feet (3.0 m) in length.[3] They are often found in shallow subtropical waters and are known to inhabit and return to specific nursery sites for breeding.[4] Often feeding at night, these sharks use electroreceptors to find their main source of prey, fish.[5] Lemon sharks use the many benefits of group living such as enhanced communication, courtship, predatory behavior, and protection.[6] This species of shark is viviparous and the females are polyandrous and have a biennial reproductive cycle.[4] Lemon sharks are not thought to be a large threat to humans.
