Emydura australis, the northern red-faced turtle, is a medium-sized aquatic turtle inhabiting rivers, streams and permanent water bodies across much of northern Australia. [1]
Turtles are reptiles of the order Chelonia or Testudines. They are characterized by a special bony or cartilaginous shell developed from their ribs that acts as a shield. Colloquially, the word "turtle" is generally restricted to fresh-water and sea-dwelling Testudines. Testudines includes both extant (living) and extinct species. Its earliest known members date from the Middle Jurassic. Turtles are one of the oldest reptile groups, more ancient than snakes or crocodilians. Of the 360 known extant species, some are highly endangered.
Chelidae is one of three living families of the turtle/tortoise suborder Pleurodira, and are commonly called Austro-South American side-neck turtles. The family is distributed in Australia, New Guinea, parts of Indonesia, and throughout most of South America. It is a large family of turtles with a significant fossil history dating back to the Cretaceous. The family is entirely Gondwanan in origin, with no members found outside Gondwana, either in the present day or as a fossil.
Podocnemididae is a family of pleurodire turtles native to Madagascar and northern South America. Podocnemidid turtles are commonly called "side-necked turtles" in direct reference to their inability to retract their heads backwards, but hide them sideways. In addition, their pelvis is fused to the shell which prevents any pelvic motion. Due to their pelvis being immobile they are unable to walk on land, which requires greater pelvis mobility. For this reason, Podocnemididae turtles are best suited for swimming and as a result live in aquatic environments. These turtles are all aquatic, inhabiting streams and other flowing water. Their shells are streamlined to aid in swimming.
The common snapping turtle is a large freshwater turtle of the family Chelydridae. Its natural range extends from southeastern Canada, southwest to the edge of the Rocky Mountains, as far east as Nova Scotia and Florida. The three species of Chelydra and the larger alligator snapping turtles are the only extant chelydrids, a family now restricted to the Americas. The common snapping turtle, as its name implies, is the most widespread.
The diamondback terrapin or simply terrapin is a species of turtle native to the brackish coastal tidal marshes of the eastern and southern United States, and in Bermuda. It belongs to the monotypic genus Malaclemys. It has one of the largest ranges of all turtles in North America, stretching as far south as the Florida Keys and as far north as Cape Cod.
The pig-nosed turtle, also known as the pitted-shelled turtle or Fly River turtle, is a species of turtle native to northern Australia and southern New Guinea.
The Turtle Mountains, are located in northeastern San Bernardino County, in the southeastern part of California. The colorful Turtle Mountains vary from deep reds, browns, tans and grays, to black. The area has numerous springs and seeps. The Turtle Mountains are also a National Natural Landmark, with two mountain sections of entirely different composition.
Pelochelys is a genus of giant softshell turtles in the family Trionychidae.
Functional extinction is the extinction of a species or other taxon such that:
The southwestern snake-necked turtle, narrow-breasted snake-necked turtle or oblong turtle is a species of turtle in the family Chelidae. It is endemic to the southwestern part of Western Australia.
The northern snake-necked turtle is a species of turtle in the family Chelidae or Austro-South American Side-necked Turtles. It is native to northern Australia and southern New Guinea.
Emydura, the Australian short-necked turtles, are a genus of turtles in the family Chelidae. It was paraphyletic with Elseya. Consequently, it was split into two genera Myuchelys and Elseya by Thomson & Georges, 2009. They can grow quite large, 30 cm or more is not unusual and have a life span of around 20–30 years. They generally do not hibernate as their warmer climate lets them remain active all year round; they also spend more time in the water than other varieties. They are considered omnivore but rely on a constant supply of meat to remain healthy, feeding on basically anything that will fit into their mouth.
Paracryptodira are an extinct clade of turtles in the order Testudines. Initially treated as a suborder sister to the Cryptodira, they were then thought to be a very primitive lineage inside the Cryptodira according to the most common use of the latter taxon. They are now considered to be a third fundamental division of the Testudines, alongside Cryptodira and Pleurodira. The paracryptodirian turtles are said to have phylogenic relationships, noted as primary subclades, within the Baenidae and Pleurosternidae. Within each subclade, lies many biodiverse turtles that are continuously being investigated and added to the fossil record.
The twist-necked turtle also known as the flat-headed turtle, is distributed widely across northern South America. Twistoofnecked turtles have extremely flat shells that help them hide from predators under rocks and debris. When threatened, this turtle withdraws by twisting its head into its shell. P. platycephala is the only species of the genus Platemys and occurs in northern and central South America. Platemys platycephala means “flat turtle, flat-head” and accurately describes the structure of the head and shell. This species inhabits shallow creek beds and frequently forages on the floor of the Amazon rainforest for insects, amphibians, and mollusks. Camouflage, head and body shape, and advanced sexual anatomy allow this species of turtle to effectively populate much of South America. Mating occurs during rainy months (March–December) and egg deposit occurs during dry months (January–March). Males have been known to behave aggressively towards females during copulation by squirting water from nostrils and biting. A few genomic studies show mosaicism exists among populations of the twist-necked turtle in Surinam. In other words, diploid and triploid levels exist among individuals at this particular location. No threats have been reported for this species and the International Union for Conservation of Nature does not have a current listing. Lack of human consumption due to the species' small size and its wide range explain why scientists are not concerned about this turtle species.
Pelodiscus is a genus of turtles in the family Trionychidae, the softshells. Based on genetic and morphological analysis there are five valid species. They are native to Eastern Asia, ranging from the Amur region, through China, Korea and Japan, to Vietnam.
Baenidae is an extinct family of Paracryptodiran turtles Known from the Aptian to Eocene of North America. While during the Early Cretaceous they are found across North America, during the Late Cretaceous they are only found in Laramidia, having disappeared from Appalachia. The majority of lineages survived the K-Pg Extinction, but the family was extinct by the latest Eocene. The name of the type genus, Baena, appears to be of Native American origin. They are primarily found in freshwater deposits, and are considered to be aquatic, with a largely generalist habit.
Chelodina (Chelydera) kuchlingi, commonly known as Kuchling's long-necked turtle or Kuchling's turtle, is a species of freshwater turtle in the family Chelidae. The species is endemic to Australia.
NASA Astronaut Group 22 is a group of twelve astronauts selected in June 2017.
Northern Rescue is a Canadian drama television series produced by Don Carmody Television (DCTV), distributed by CBC Television in Canada and internationally on Netflix. The first season of 10 episodes debuted on March 1, 2019. It stars William Baldwin as a search and rescue commander who, after the death of his wife, relocates from Boston with his three children to live with his sister-in-law in the fictional small town of Turtle Island Bay, Ontario, where he grew up.
