Green turtles are long-lived and may take up to 59 years to reach sexual maturity Undertaking tremendous feats of navigation, adults return to the same beach to breed each season, part of the population in Brazil astonishingly migrates around 2,250 kilometres across the open ocean to breed on the Ascension Islands . Mating tends to occur just offshore of the nesting beaches; using a curved claw on each front flipper and a flat nail at the end of the tail, males are able to grip their mates . Females haul out onto the beach at night and dig large nests with their back flippers beyond the high tide mark, they typically lay between 100 and 150 eggs in one nest and then proceed to cover the eggs with sand; the whole process takes around two hours . A single female returns to breed only once every two to five years but will lay up to nine nests in that one season . Incubation takes between 45 and 70 days, and temperature has been shown to determine of the sex of hatchlings; with females being produced at warmer temperatures . Breaking open their eggs with a special hooked 'egg tooth' that will subsequently be lost; hatchlings use their powerful front flippers to reach the surface, and then proceed to the sea . The soft-bodied juveniles are particularly vulnerable at this time from a variety of predators, such as ghost crabs and gulls on the beach to sharks and dolphins in the water . Unlike other marine turtles, adult green turtles are almost exclusively herbivorous, grazing on seagrasses and algae ; it is assumed that juveniles are more omnivorous although the exact composition of their diet is unknown

The goliath grouper may be solitary or occur in groups of up to 50 or more individuals. Home range appears limited and the fish produces a booming sound when threatened by divers or large sharks. Variations of these vocalizations also undoubtedly have intraspecific communicative properties . During the breeding season from July through September, goliath groupers gather together at breeding sites in groups of 100 individuals or more, for periodic spawning. The fertilised eggs are scattered in the water column of the ocean and develop into kite-shaped larvae with long dorsal fin spines and pelvic fin spines . About a month or more after hatching, the larvae mature into juveniles of just 2.5 cm long and settle preferentially into mangrove habitat . These fish are very long-lived with a slow growth rate and late sexual maturation. Males begin breeding at four to six years and females mature at six to seven years. However, if goliath grouper are like most other groupers, they may undergo a sex-change part way through life, starting out as a female and becoming males at some later time, but this has never been observed in this species . Goliath groupers feed on crustaceans, such as spiny lobsters, shrimps and crabs as well as fish including stingrays and parrotfish, in addition to octopuses and young sea turtles. Despite having teeth, the fish engulfs its prey and swallows it whole. Before the goliath grouper reaches full-size it is susceptible to the attack of barracuda, king mackerel and moray eels, as well as sandbar sharks and hammerhead sharks . Once fully grown, humans and large sharks are the goliath grouper's only predator .
