The sharptooth lemon shark is reportedly a sluggish shark that swims slowly near the bottom, frequently resting on the substrate. This shy shark is generally reluctant to approach divers, even when food is used to lure them near. Young sharks are said to be more inquisitive, and a shark of any age is likely to respond to being provoked by humans, or approached by boats, with aggression. The majority of the sharptooth lemon shark's diet consists of bottom-dwelling bony fishes and stingrays . This is a viviparous shark, thus the embryos develop inside, and receive nutrition from, the mother for about ten months. Litters can vary from 1 to 13 young, with each pup measuring about 45 centimetres .

A generally common species found in a variety of coral habitats from tide pools to depths of at least 40 m; prefers the 1 to 10 m reef zone. Juvenile prefers shallow, protected coral thickets . Benthic and benthopelagic . Feeds mainly on fishes (75-95%) and to a lesser extent on crustaceans. In the Red Sea, it feeds early in the morning and late afternoon ; but at Madagascar, it appears to feed more at night . Implicated in ciguatera at some of the islands in Pacific region. In Hong Kong live fish markets .
Carcharhinus amblyrhynchos (Bleeker, 1856) (Gray reef shark)

Occurs on continental and insular shelves and oceanic waters adjacent to them . Common on coral reefs, often in deeper areas near drop-offs to the open sea, in atoll passes, and in shallow lagoons adjacent to areas of strong currents . Coastal-pelagic near the bottom, near drop-offs at 1-275 m . Forms daytime schools or aggregations in favored areas . Although active during the day, it is more active nocturnally . Viviparous, with 1-6 pups . Feeds on reef fishes, squids, octopi, crabs, lobsters and shrimps . Tends to be aggressive under baited conditions and readily enters into a frenzy feeding pattern, at which time it may become quite dangerous. Repeatedly incriminated in human attacks. Utilized for human consumption, fishmeal, and other shark products. Minimum depth from Ref. 6871. Maximum length of female taken from Ref. 5213.

The biology of the bull shark is still little known but it shows extraordinary physiological adaptations that allow it to persist in both freshwater and saltwater. Bull sharks have been captured in places you would never imagine a shark to be found; in the foothills of the Peruvian Andes, 3,700 kilometres up the Amazon River; and in Lake Nicaragua, the largest lake in Central America. However, the bull shark may not be able to complete its entire life cycle in freshwater, and all sharks in freshwater require access to saltwater through rivers and estuaries . Its swims slowly and heavily, usually near the bottom, concealing its surprising agility and speed employed when attacking prey , and deceiving one into believing this may not be one of the most dangerous species of tropical shark, as it is frequently cited . Along with the great white and tiger shark the bull shark is responsible for the most accidents involving people ; a result of its tendency to take large prey and the proximity of its habitat to the activities of humans . The bull shark's broad and varied diet includes bony fishes, other shark species , sea turtles, birds, dolphins, and terrestrial mammals . The bull shark is viviparous, giving birth to 1 to 13 young in each litter after a pregnancy of 10 to 11 months . The female gives birth in late spring and early summer in both hemispheres, in estuaries, river mouths, and very occasionally in freshwater lakes . Mating takes place at the same time of the year but it is unknown where exactly as it has never been directly observed .

During the day the nurse shark is a sluggish animal, spending most of its time resting on sandy bottoms, or in crevices in rocks and coral reefs. Often several nurse sharks may congregate when resting, sometimes even piling on top of one another . At night however, the nurse shark actively roams the sea bottom and reef for prey. It feeds on bottom invertebrates such as spiny lobsters, shrimps, crabs, sea urchins, squid and octopi . It is also feeds on fish, its nocturnal nature enabling it to prey on resting fish that would be too active during the day to capture . The nurse shark's small mouth and large pharynx enable it to feed by a unique suction method, effectively making the nurse shark the 'hoover' of the ocean floor. By cupping its mouth over a hole or crevice and expanding its throat, it creates a vacuum that sucks prey out of their hiding . This suction-feeding is also useful for extracting snails from their shells , and it will dig in sand to root out prey sensed by its fleshy barbels . The nurse shark is one of few sharks in which courtship behaviour is relatively well known . The male swims alongside the female, grabs one of the pectoral fins in his mouth, rolls her over and they mate . A large number of males will often try to mate with a single female, and females often bear numerous bite-scars and bruises received during mating attempts. It is therefore not surprising that females frequently try to avoid males by swimming in very shallow water, where they can bury their pectoral fins in the sand . Nurse sharks are ovoviviparous , a method of reproduction whereby the young develop inside a weakly-formed egg shell within the mother, receiving nourishment from their yolk sac, for five to six months . The females move to shallow seagrass beds and coral reefs to give birth to 20 to 30 pups in late spring and summer . Like many sharks the nurse shark is slow growing, with males not reaching maturity until 10 to 15 years of age, and females 15 to 20 years .

Just as interesting as the first shark dive but not as deep. We went for a short dive around a wreck and bommies nearby. Saw lots of sucker fish.
