This long-lived fish has a fascinating and complex life-history. It is a protogynous hermaphrodite, meaning that individuals first function sexually as females and then later, at least some of the mature females change to males. It is thought that this sex change can occur at a wide range of sizes and ages, although not all individuals change sex. A brown-marbled grouper can live for over 40 years, an incredibly long time for a fish, and can reproduce for over 30 of those years, during which time they form large aggregations to spawn . The brown-marbled grouper is one of the largest fish predators on coral reefs , and is mainly active at dusk, when it feeds on fishes, crabs and cephalopods . This secretive and wary fish may be ciguatoxic ; that is, the flesh may be contaminated with a toxin that can make humans very sick if consumed.

Blue-spotted stingrays live alone or in small groups , migrating in large schools into shallow sandy areas on the rising tide in order to feed, and dispersing back into the ocean as the tide falls to shelter in the coral crevices of the reef . Feeding most commonly occurs during the day, but sometimes also at night , and the diet consists largely of worms, shrimps, crabs, molluscs and small fish . Prey is often detected through electroreception, a system which senses the electrical fields produced by the prey . Not all small fish and invertebrates are potential prey, as blue-spotted stingrays can often be found at 'cleaning stations', areas of reef where large fish line up and tiny fish or shrimp pick off their dead skin and parasites . In courtship, males often follow females, using their acutely sensitive 'nose' to detect a chemical signal emitted by the female that indicates she is receptive. Breeding occurs from late spring through the summer, and gestation can last anything from four months to a year . Reproduction is ovoviviparous, meaning females give birth to live pups that have hatched from egg cases inside the uterus . Up to seven pups are born per litter and each juvenile is born with the distinctive blue markings of its parents in miniature .

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 .

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 .
