Lemon sharks are a popular choice for study by scientists as they survive well in captivity, unlike many other species such as the great white shark , which dies in captivity because of food refusal. The species is the best known of all sharks in terms of behaviour and ecology , mainly thanks to the enormous effort of Dr.[1] Lemon sharks were present but nervously swimming at approx 1.5m ft off the bottom in a large circle from the sand bottom 20 m to the ridge of live rock to the west that makes up Cap?n Kurel reef. I observed 20-30 different individuals but kept some distance so as not to disturb Walt?s camera work by disturbing the lemons with my bubbles. Lemon sharks are timid and will often swim away when approached by humans. They’re know to form small groups based on a size and sex based hierarchy.

Lemon sharks are also sold for their meat. Populations in the western north Atlantic and eastern Pacific Ocean are declining due to overfishing . Lemon shark females reach sexual maturity by the time they’re about 2.45 metres in length. The females give birth once every couple of years to a litter of 60-65 centimetre pups . Lemon sharks can be found in oceanic water during migration but tend to stay along the continental and insular shelves. The lemon shark is also known to form loose aggregations based on size and sex and have been seen congregating near docks and fishing piers during the night, returning to deep water during the day.
Lemon sharks have between 3 and 5 ridges, or rows, of teeth on both the upper and lower jaw. Their long thin sharp teeth are designed to catch slippery fish, the mainstay of the shark? Lemon sharks are one of the larger species of sharks, commonly obtaining lengths between 95-120 inches (240-300 cm). The maximum length that can be reached by this species is between 125-135 inches (318-343 cm).
