An Australian river turtle with a distinctive green punk-rock hairstyle, two spines under its chin and the ability to breathe through its genitals figure in a new list of reptiles in Danger of extinction.  The Mary River turtle, originally from Queensland, Australia, has the unusual ability to breathe underwater through specialized glands in its cloaca, a posterior opening for its excretion and reproduction.
This biological function allows the turtle to be known as a "butt vent": stay underwater for up to three days. That ability also gives these turtles a vibrant green mohawk, as a result of the algae that grows on their heads due to the prolonged time they spent submerged.
Rikki Gumbs, a reptilian biologist at the Zoological Society London (ZSL), told CNN that from the exotic pet trade in the 1960s and 1970s, turtles were often kept as pets and were already in danger of being threatened when they were first recognized as a species in the 1990s.
the tortoise takes a long time to reach sexual maturity, taking between 25 and 30 years, "he said." As his vulnerability was discovered late, we lost an entire generation due to the pet trade and now its population has become very small. "
The turtle figures in the 29th place on the first such reptile list, ZSL record of Evolutively Different Creatures and Globally Endangered The highest-ranking reptile is Madagascar's large head turtle, which is at risk due to human exploitation for food and commerce, along with the largest marine turtle in Madagascar. The world, the leatherback turtle and the gharial, a crocodile found in the rivers of Nepal and northern India. Less than 250 gharials are still alive.
Both freshwater and sea turtles are under pressure worldwide. For example, in Hainan, an island province in southern China, sea turtle meat and shells are in great demand and over the past 30 years, Hainan has seen a decline in the number of turtles that come to spawn.
Sea turtles have lived for more than 110 million years and are now considered endangered, depending on the work of conservationists to prevent their extinction in the next 50 years.
"Releasing the turtle back to the ocean is a very good feeling," Fikiri Kiponda, a marine conservationist, told CNN. "You feel like you've done something tangible and I think everyone would like to do that … So I guess it's a unique job"
