Lucky turtles, also known as pig-nosed turtles and flying river turtles, are mostly found in northern Australia, southern New Guinea and Irian South of Jaya, it is the only species remaining in the two-clawed softshell turtle family. Highly aquatic, in addition to laying eggs, it lives in water all year round, so the limbs are transformed into flippers like sea turtles, which is very rare and is not encountered in freshwater turtles. The nose is long and fleshy, like a pig's nose, so it has the reputation of lucky turtle. It is a restricted trade animal listed in Appendix II of the Washington International Convention for the Protection of Endangered Animals. The wild number is very limited, but it is a huge number under artificial breeding.

      The Lucky Turtle is one of the most peculiar looking freshwater turtles. The carapace is round, dark grey, olive grey or brownish grey with a row of white spots on the edge. The edges are slightly serrated, and the bones on the outer edge are well developed and the structure is complete, so there is no skirt like the turtle. There is also no scutellum, but rather slightly wrinkled skin. There is a row of spiny ridges in the center of the carapace. The plastron is light in color, white, creamy white or light yellow, slightly cross-shaped. The head is of moderate size and cannot be retracted into the shell. There is a grey stripe behind the eye. The nose is thick and fleshy, and very long, like a pig's nose. The limbs are specialized in fins for aquatic life and cannot be retracted into the shell. It is also characteristic of the presence of two prominent claws at the near midpoint of each forelimb. The tail is short and the back is covered with a row of crescent-shaped scales that taper from the base to the tip of the tail. There are distinct folds of skin on the sides below the tail, extending from the base of the thigh to the hindquarters.

       Lucky turtles are highly aquatic freshwater turtles that can Living in deep water and rarely going ashore, it is a master swimmer among turtles. Adult Lucky Turtles are very aggressive, and if they don't have enough hiding places in feeding, they will leave numerous scars on each other's carapace skin. In terms of diet, lucky turtles are full of opportunists. They eat whatever they encounter. If they are not nutritious, they will rarely take the initiative to prey. In addition to laying eggs, they live in water all year round and are highly aquatic reptiles and omnivores, but hatchlings are carnivorous, have a large appetite, and are aggressive by nature. The tail of the adult male turtle is longer, and the position of the cloaca is relatively backward; while the tail of the female turtle is shorter and smaller.

       lucky turtles are full of omnivores, and are slightly more herbivorous , so you can usually feed vegetables, as well as fruits such as figs, apples, kiwi and bananas, and occasionally add a small amount of animal food such as fish shrimp. You can also feed synthetic fish feed or turtle feed, and add calcium and vitamins appropriately. Healthy Lucky Turtles eat a lot, almost from morning to night. After each feeding, use a net bag to salvage food residues to keep the water clean. This is especially true when feeding foods such as bananas that tend to degrade water quality.

       Young turtles tend to be carnivorous, so you can feed more fish, shrimp, beef , earthworms, red worms and other animal bait to meet their growth needs. Because the limbs of the lucky turtle are specialized in the shape of fins, it is not conducive to tearing the food, so it should be cut into appropriate small pieces before feeding, so that the turtle can swallow it. Young turtles generally do not like herbivores, but some owners think that they prefer fruits and vegetables with higher sweetness such as corn, bananas, pears, etc. In addition, they can also try feeding various aquatic plants such as bitter grass, hornwort, chrysanthemum algae, etc. To facilitate balanced nutrition.

       In origin, the dry season between July and October is In the breeding season of Lucky Turtles, adult female turtles climb up the sand dunes on the shore at night, and then dig a hole about 20cm deep. Each nest lays 7-19 eggs (also called 7-39 by the author), and the eggs are round. Shaped like a ping pong ball. After the embryo matures, it will enter a dormant state in the egg, until the rainy season flood or after the heavy rain, the juvenile tortoise will break out of the ground. To be precise, this tortoise is unique in the world. It is said that ordinary oviparous animals with shells are afraid of water during their unformed period (still in their shells), while Lucky Turtle's derailment encounters water, (in the natural environment, the arrival of floods in the rainy season will bring them abundance food) This kind of animal can be said to be born selectively, and the probability of successful artificial reproduction is relatively small.
