Juveniles are encountered under ledges, or in holes of outer lagoon patch reefs or semi-protected areas of exposed channels and outer reef flats. Subadults move to reef front holes and surge channels. Large adults inhabit ledges and caves in areas of rich coral growth on clear lagoon, channel, or seaward reefs . Benthopelagic . Feed on sponges and other encrusting organisms ; also on tunicates. Form pairs. Young and adults may clean much larger fishes such as sunfish . Frequently exported through the aquarium trade. Juveniles are distinguished by a white dorsal-fin margin .

Commonly found in weedy areas and especially around reefs, where they usually swim snout-down among sea whips . A solitary ambusher of small fishes and crustaceans that lurk among branching coral or gorgonians. Often swims behind large herbivorous fishes to sneak up on prey. Mouth opens to diameter of body to suck in prey . Marketed locally. Has been traded as an aquarium fish at Ceará, Brazil .

The southern stingray is an active swimmer that feeds primarily at night, on a diet of invertebrates and small fishes. They feeding by flapping their wing-like pectoral fins to disturb the sand, and expose their prey . This bottom-dwelling species is often found singly or in pairs, except in the summer months when it migrates in schools to higher latitudes . Very little is known about the natural mating behaviour and reproductive biology of the southern stingray. Mating stingrays are rarely encountered in the wild; during one such rare occasion, the male was observed closely following the female, and then biting her before grasping the female's pectoral fins with his mouth, and then copulating. It is thought that southern stingrays are polyandrous, as a female was observed mating with two males in quick succession . The southern stingray is ovoviviparous, a method of reproduction in which the egg develops within the female's brood chamber. The pups hatch from their egg capsules inside the mother, and are born soon afterwards . In captivity, gestation lasted 135 to 226 days, after which a litter of two to ten young were born .

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
