An Australian river turtle with a distinctive green punk-rock hair- style, two spikes under its chin and the ability to breathe through its genitals is on a new list of endan- gered reptiles.
The Mary River turtle, native to Queensland, Australia, has the unusual ability to
breathe underwa- ter through spe- cialized glands in its cloaca — a posterior opening for excretion and reproduction.
This biological function allows the turtle — referred to as
a “butt
breather” — to stay underwater for up to three days. That ability also usually pro- vides these turtles with a vibrant
green mohawk, the result of algae growing on their heads because of the extended time spent submerged.
Rikki Gumbs, a reptile biologist at Zoological Society London (ZSL), told CNN that because of the exotic pet trade in the 1960s and ’70s, the tur- tles were often kept as pets and were already at risk of being
endangered when they were first recognized as a species in the 1990s.
“The turtle takes
a long time to reach sexual maturity, taking up to 25 to 30 years,” he said. “As their vulnera- bility was discov- ered late, we lost a whole genera- tion due to the pet trade and now their population has become very
small.”
The turtle comes in at No. 29 on the first list of its kind for reptiles, ZSL’s register of Evolutionarily Distinct and Globally Endangered creatures. The highest-ranking reptile is the Madagascar big- headed turtle, which is at risk due to human exploitation for food and trade.
Joining them are the world’s largest sea turtle, the leatherback, and the gharial, a crocodile found in the rivers of Nepal and north- ern India. Fewer than 250 gharials are still alive.
Both freshwater and sea turtles are under pres- sure worldwide. For example, in Hainan, an island province in south-
ern China, sea turtle meat and shells are in high demand and in the past 30 years, Hainan has seen a decrease of tur- tles coming in to lay eggs.
Sea turtles have lived for over 110 million years and are now consid- ered to be endan- gered, relying on the work of con- servationists to prevent their extinction over the next 50 years. “Releasing the turtle back into the ocean is a very good feel- ing,” Fikiri Kiponda, a marine conserva- tionist, told
CNN. “You feel like you’ve done something tangi- ble and I guess everybody would love to do that... So I guess it’s unique work.”
