Plight of genital-breathing punk turtle highlighted by scientists

A punk turtle with a green mohican and highly unconventional lifestyle is the star attraction in a new list of endangered reptiles.

The Mary River turtle (Elusor macrurus) has a head crowned by vertical strands of algae that also grow on its body.

In addition, it sports face furniture in the form of long fleshy barbels under its chin.

However, perhaps the Mary River turtle’s most unusual feature is its ability to breath through its genitals.

The turtle has gill-like organs within its cloaca – a multi-purpose orifice used by reptiles for excretion and mating – that allow it to stay underwater for up to three days.

The turtle, which measures up to 40 cm, lives in just one location – the Mary River in Queensland, Australia.

Its docile nature – more hippy than punk – historically made it a popular pet. In the 1960s and 1970s its nest sites were mercilessly pillaged for the pet trade.

Today, the Mary River turtle is one of the world’s most endangered turtle species.

The turtle is just one of many weird and wonderful species featured in the Zoological Society of London (ZSL’s) Evolutionarily Distinct and Globally Endangered (Edge) Reptiles list.

The Mary River turtle ranks number 30 in the league table of 572 reptiles. Top of the list is one of its cousins, the Madagascan big-headed turtle (Erymnochelys madagascariensis), with an Edge score higher than that of any other amphibian, bird or mammal.

Edge reptiles co-ordinator Rikki Gumbs said: “Reptiles often receive the short end of the stick in conservation terms, compared with the likes of birds and mammals. However, the Edge reptiles list highlights just how unique, vulnerable and amazing these creatures really are.

“If we lose these species, there will be nothing like them left on Earth.”

The researchers outline how they compiled the Edge reptiles list in the journal Public Library of Science ONE.

Each species is given a score which combines extinction risk with how isolated or unique the species is.

A large number of turtles and tortoises feature on the reptiles list, along with lizards and snakes.
