First thought: what the heck is that? I'd say one of the more mysterious and bizarre species.
The Mata Mata Turtle is a fresh water turtle found in South America, primarily in the Amazon and Orinoco basins. These are large, sedentary, brown or black turtles that sport a large triangular flattened head characterized with many tubercles and flaps of skin and a "horn" on its long and tubular snout. There are three barbels on the chin and four additional barbels at the upper jaw, which is neither hooked nor notched. These features may be meant to allow the turtle to resemble a piece of bark, with the head resembling fallen leaves, camouflaging it from possible predators.

This species grow quite large, is slow-moving and prefers shallow water. They have wide mouths that occupy the entire front of the face, often appear smiling, and extraordinarily long necks. Since they can grow to 18 inches long, their size doubles when the neck is extended.

The carapace may reach up to 12 inches in length. These are the most commonly kept turtle in eastern Australia; it is generally shy but wil adapt quickly into captivity and is the easiest of all Australian species to maintain. Newly captured specimens will musk, emitting a strong smelling liquid as a means of defense. This, however, ceases as they settle into captivity.

Leatherbacks are the largest turtles on Earth, growing up to seven feet long and exceeding 2,000 pounds. These reptilian relics are the only remaining representatives of a family of turtles that traces its evolutionary roots back more than 100 million years. Once prevalent in every ocean except the Arctic and Antarctic, the leatherback population is rapidly declining in many parts of the world.
While all other sea turtles have hard, bony shells, the inky-blue carapace of the leatherback is somewhat flexible and almost rubbery to the touch. Ridges along the carapace help give it a more hydrodynamic structure. Leatherbacks can dive to depths of 4,200 feet — deeper than any other turtle—and can stay down for up to 85 minutes.
Unlike their reptilian relatives, leatherbacks are able to maintain warm body temperatures in cold water by using a unique set of adaptations that allows them to both generate and retain body heat. These adaptations include large body size, changes in swimming activity and blood flow, and a thick layer of fat.
Leatherbacks undertake the longest migrations between breeding and feeding areas of any sea turtle, averaging 3,700 miles each way. After mating at sea, females come ashore during the breeding season to nest. The nighttime ritual involves excavating a hole in the sand, depositing around 80 eggs, filling the nest, leaving a large, disturbed area of sand that makes detection by predators difficult, and finally returning to the sea.
It is estimated that only about one in a thousand leatherback hatchlings survive to adulthood. Eggs are often taken by humans from nests to be consumed for subsistence or as aphrodisiacs. Many leatherbacks fall victim to fishing lines and nets, or are struck by boats. Leatherbacks also can die if they ingest floating plastic debris mistaken for their favorite food: jellyfish.
Leatherbacks are currently designated as endangered under the U.S. Endangered Species Act. The number of leatherbacks in the Atlantic appears to be stable or increasing, but the Pacific population is declining at an alarming rate due to egg harvest, fishery bycatch, coastal development, and highly variable food availability. Some Pacific populations have disappeared entirely from certain areas, such as Malaysia.

Naturally restricted to a small area in Little Namaqualand, an arid region in the west of South Africa, here it normally lives on rocky outcrops, where it forages among the rocks for the tiny succulent plants it eats.
Males measure 2.5 to 3 inches, while the larger females measure up to almost 4 inches; they weigh about 3.5 – 6 oz. This species has a flattened shell with slightly serrated edges. The orange-brown shell is covered in hundreds of black spots. The males have a noticeably concave belly.
The species is threatened by traffic on roads, habitat destruction and poaching for the pet trade. Many are taken from their natural habitat each year, and nearly all subsequently die as a result, as they do not readily adapt to typical captive diets and climatic change.
However, their diet (while very varied) is not highly specialized, which would allow the species to adapt well to captivity, provided that proper attention is paid to temperature, dryness and a sufficiently varied diet.

The videos show her going from her nest until she disappears into the Atlantic Ocean on Crescent Beach, Florida. The leatherback is the largest, deepest diving, and most migratory and wide ranging of all sea turtles. The adult leatherback can reach 4 to 8 feet in length and 500 to 2000 pounds in weight.
