The leatherback turtle is the largest marine turtle and one of the largest living reptiles. Leatherbacks are one of the most migratory of all marine turtle species, making both trans-Atlantic and trans-Pacific crossings. They are easily distinguished by their carapace, which is leathery, not hard as in other turtles, and by their long front flippers.
Leatherbacks have a unique system of blood supply to their bones and cartilage. This enables their body temperature to stay several degrees above the water temperature and allows them to tolerate cold water, rather like a mammal. They can dive to depths of up to 1,200m, much deeper than any other marine turtle.
Recent DNA analysis confirms that Atlantic and Pacific populations are genetically distinct lineages of a single species. In turn, nesting Pacific leatherback populations are separated into two genetically distinct populations (eastern and western populations).
The leatherback can reach up to 180cm, and 500kg in weight.
The species carapace (shell) is dark with white spots.
Juvenile leatherbacks may remain in tropical waters warmer than 26°C, near the coast, until they exceed 100cm in curved carapace length. Adults are pelagic and live in the open ocean, sometimes in temperatures below 10°C.
Female leatherbacks may lay 4 to 5 times per season, each time depositing 60 to 120 eggs. Leatherbacks appear to nest once every two or three years with an incubation period of approximately 60 days.
The large size of leatherbacks is all the more remarkable given their low energy, low protein diet of soft-bodied creatures such as jellyfish, squid and tunicates ('jelly fish-like' marine invertebrates).
Previous Population and Distribution
The global population for this species was estimated to be 115,000 adult females in 1982. By 1996 this had been revised down to about 30-40,000. Leatherback populations in the Pacific and Indian Oceans have undergone dramatic declines in the past forty years. For example, the nesting colony at Terengganu, Malaysia went from more than 3,000 females in 1968, to 20 in 1993, to just 2 in 1993 - there are no signs of recovery.
Similar scenarios have occurred in Indonesia, Sri Lanka, Thailand, and Mexico. Numbers of females recorded at four formerly major Pacific rookeries have declined to about 250 in Mexico, 117 in Costa Rica, two in Malaysia, and fewer than 550 in Indonesia.
Current Population and Distribution
Leatherbacks have been recorded as far north as Alaska, and as far south as Africa's Cape of Good Hope.
The Pacific may now have as few as 2,300 adult females.
However, not all leatherback populations have declined: in southern Africa, three decades of strong protection have increased the small annual nesting population more than fourfold. Recent reports mention that west Africa has an important population with around 10,400 nests per season, but the total area occupied for the leatherbacks is not well known and there is no available historical information on nesting trends of this population.
The most important nesting beaches now remaining in the Atlantic are found in Suriname, French Guiana, and Gabon. In the Pacific, the few remaining important beaches are in Indonesia, Mexico and Costa Rica, with other rookeries found in Nicaragua, Panama and Guatemala.
- Turtles are divided into two groups, according to how they retract their necks into their shells (something the ancestral Proganochelys could not do). The mechanism of neck retraction differs phylogenetically: the suborder Pleurodira retracts laterally to the side, anterior to shoulder girdles, while the suborder Cryptodira retracts straight back, between shoulder girdles.

- Six of the seven species of sea turtles that swim the planet’s waters— leatherback, loggerhead, Kemp’s ridley, green, olive ridley, and hawksbill —are found in every ocean except the Arctic.
Turtles need a minimum 30-gallon size aquarium with a screened top. Their habitat should include mostly water, plus a bit of land for basking. Turtles eat a combination of vegetables, turtle food and, depending on the species, insects.
