The fast-swimming blacktip shark is an active fish that can be seen leaping out of the water and spinning before dropping back into the sea . This agile spinning behaviour is thought to be used while feeding on small schooling fishes, such as herrings or sardines. The sharks propel themselves vertically, up through the school, spinning and snapping in all directions until they breach the surface . As well as feeding on schools of small bony fish, the blacktip shark occasionally preys on squid, cuttlefish, octopi, crabs and lobsters . Blacktip sharks often occur in large schools, which with their highly energetic temperament, can result in competitive feeding frenzies when confronted with immense shoals of fish or the waste of a shrimp trawler being dumped overboard . Mating in the blacktip shark occurs from May to June, and pregnancy lasts for about one year . The viviparous blacktip shark gives birth in shallow, coastal waters, to between one and ten pups in May or June. The young remain in the calm, food-rich nursery area until autumn .

Despite its docile nature during the day this nocturnal shark can become aggressive when hunting at night, thrashing through coral reefs looking for potential prey. The whitetip reef shark usually hunts alone, but is non-territorial and will occasionally work in cooperation with others in the pursuit of prey . Feeding primarily on bottom-dwelling octopus, lobsters, crabs and bony fish, it often chases its prey into a crevice before jamming its body in after it, sealing the exit . The extremely posterior location of the first dorsal fin compared to those of other sharks is an adaptation to this feeding habit, which allows them to get their heads and mouths much further into the gaps and holes in the coral . The whitetip reef shark's mating season varies with location . Reproduction is viviparous and after a gestation period of around a year the female will give birth to one to five live pups, which are completely independent at birth . Both sexes reach sexual maturity at approximately 5 years old, and it is estimated that this species can live to an age of 25 years .

This powerful swimmer is well known for its tendency to enter incredibly shallow water, and is often found in water only 30 centimetres deep or less, with its distinctive dorsal fin protruding from the surface of the water. It is also found near the bottom or in mid-water in deeper water, singly or in small groups . It feeds on a wide variety of small fish and invertebrates, including mullet, groupers, wrasses, cuttlefish, squid, shrimp . Blacktip reef sharks are viviparous, and therefore the embryos develop inside the mother, for about 16 months. Females generally give birth between late winter and early summer, to between two and four pups . However, reproductive cycles appear to vary throughout the blacktip reef shark's range, with reports of annual, biannual and biennial reproductive cycles . The blacktip reef shark is not an extremely dangerous species, although it is responsible for several provoked and unprovoked attacks on humans. Many are on people that are swimming or wading on reefs, presumably because they were mistaken for small prey. These sharks are more cautious when encountering divers and can usually be driven off .

Occurs inshore and offshore, from the intertidal to at least 70 m depth . May enter brackish water. Feeds on worms, crustaceans, snails, and bony fishes . Ovoviviparous . With litters of up to 4 young. Size at birth about 17 cm WD . Caught frequently but in lower numbers, by bottom trawl and inshore gillnet fisheries in some areas. Utilized for its meat, but of limited value due to its small size .
Dasyatis centroura (Mitchill, 1815) (clam cracker)
Found over sandy and muddy bottoms. Feeds on bottom-living invertebrates and fishes. Ovoviviparous . Wings marketed fresh, smoked, dried-salted; used for fishmeal and oil. Harmful to shellfish banks; dangerous to bather...

Harmful to shellfish banks; dangerous to bathers and fishers due to its poisonous spine. May attain well over 100 cm TL. Warm season visitor to coastal waters .
