Lemon shark

Presentation

The Lemon shark is a robust shark living in the tropical and subtropical waters of the Atlantic and Pacific. It owes its name to the yellow-brown tint of its skin, which provides effective camouflage on sandy bottoms. This species is particularly studied by scientists because of its tolerance in captivity and its regular presence in shallow coastal areas. It has two dorsal fins of almost identical size, a distinctive feature among sharks. The Lemon shark often frequents mangroves during the first years of its life, which serve as a protective nursery. It is considered to be of little danger to humans unless provoked.

Its massive body and yellowish to brownish coloring distinguish it from other coastal sharks. Its two dorsal fins are of similar size, unlike most species where the first clearly dominates. Its head is broad and rounded, with a short muzzle.

Characteristics

Indicative values: they vary by subspecies, sex and region.

Habitat and distribution

The Lemon shark frequents shallow coastal waters, lagoons, mangroves and coral reefs. Juveniles often stay near mangroves, rich in food and shelter. Adults may venture into slightly deeper waters but generally stay close to shore.

Behaviour

This species is rather sociable and sometimes forms groups, a rare behavior among sharks. It is mainly active at night, during which it actively hunts. The Lemon shark demonstrates notable learning ability, demonstrated in numerous laboratory studies.

Reproduction

Reproduction is viviparous, with a placenta nourishing the embryos during gestation. Females give birth to around ten young on average after a gestation of around one year. The newborns immediately move to the mangrove areas which serve as a refuge from predators.

Peculiarities

The Lemon shark is one of the most widely used shark species in scientific research due to its good tolerance to captivity. It exhibits fidelity to the birth site, sometimes returning there to reproduce.

Threats and conservation

Overfishing and the destruction of mangroves, essential for the survival of juveniles, threaten the species. Demand for shark fins for some Asian markets is also contributing to its decline. The slow rate of reproduction makes it vulnerable to fishing pressure.
