Found between the shore and 100 m depth, on sand or mud bottoms rich in organic matter. Feed mainly on shrimps , amphipods, crustacean larvae and annelids. The whole life cycle develops on the continental shelf. During reproduction in May and September, adults gather in shallow waters of the estuaries and along the coast. Sexual activity takes place during the rainy season which corresponds to quite a large influx of organic matter, thereby ensuring food for the breeding fish. Sexual dimorphism affects the interorbital width and pectoral fin length of the hidden side. Juveniles remain planktonic for a long time with a high growth rate of >5% per day .

A benthic and solitary species abundant in shallow rocky and grassy areas and on coral reefs; less common in turbid bays or harbors. Its bite is very dangerous . Active during the day, sometimes together with other predators. Feeds on fish and crustaceans . Marketed fresh and salted . Usually seen with its head protruding from a hole and the rest of its body concealed . Has been traded as aquarium fish at Ceará, Brazil .

A benthic and solitary species found commonly on reefs and rocky shore areas. Feeds on small fishes and crustaceans . At Fernando de Noronha Archipelago, offNE Brazil, forages for sally lightfoot crabs on exposed reefs at ebb tide and in tide-pools mostly at daytime. Able to withstand up to 30 minutes out of water while foraging, uses four main tactics both in and out of the water. Searches for prey at pool rims and rock bases poking into crevices and holes, stealthily approaches previously sighted prey, chases prey and ambushes prey from under rocks and crevices. Hunting success varies with employed tactic, but overall success is about 50%. May move up to 6 meters in about 1 hour while foraging on the exposed reef. Its crab hunting is mostly visually guided and a fish darting nearby a stealthily foraging moray may cause it to miss the strike; the missed crab may be chased up to 5 m on the reef. Able to strike with its body partly or entirely out ofthe water, usually strikes from a distance of 5 to10 centimeters. Small crabs are swallowed whole, whereas larger ones are torn apart by a combination of tugging, rotating, knotting, and thrashing movements. Handling time is related to prey size, the largest crabs (carapace width 2.3-3.2 times larger than moray’s head width) broken up and swallowed within 90 to 240 seconds. Attracted to plastic or rubber decoys dragged on a nylon string nearby, striking at these .

Found over all types of bottom, but mainly around coral reefs and on vegetated sandy areas. In turbid as well as clear water . Often forms large aggregations, especially during the breeding season. Feeds at night on small fishes, bottom-living crabs, shrimps, worms, gastropods and cephalopods. Good food fish, it is marketed fresh.

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

Hawksbills may take decades to mature and it could be between 20 to 40 years before they are ready to breed . Upon reaching sexual maturity, a female will typically lay up to five clutches of around 100 to 140 eggs in one breeding season, and then wait a few years before nesting again . Nesting is much more dispersed than in other marine turtles, but individuals do tend to return to a particular beach season after season . Having survived the dash to the sea, hatchlings are believed to spend their first few years in the open ocean before returning to more sheltered coastal waters. Recent studies indicate that the oceanic phase may be shorter for hawksbills, or even omitted in certain regions, as hatchlings swim less vigorously than those of other species . Probably less than one out of 1000 eggs will survive and reach adulthood . Adults are opportunistic predators, using their sharp beak to prize invertebrate prey from crevices within the reef. Unusually amongst marine animals , sponges make up the majority of the hawksbill's diet .
