Triboniophorus aff. graeffei is a species of giant air-breathing land slugs specific to Mount Kaputar in Australia with a distinctive hot pink hue. Taxonomists have confirmed the slug's distinction from Triboniophorus graeffei.
Distribution and habitat
The slugs have only been found atop Mount Kaputar, an inland mountain near Narrabri in northern New South Wales within Mount Kaputar National Park, at an altitude around 1,500 metres (4,921 ft 3 in) surrounded by snow gum trees. They have been observed to stay in this area. Most of the top of the mountain is designated wilderness. While the mountain is surrounded by dry plains, it receives more rainfall and snow and its temperature is 10 degrees cooler.
Life
The slugs can be seen on cool, wet, misty mornings by the hundreds. During the day, they hide in the plant litter at the base of the trees. At night, they come out and climb the tree to eat algae and mosses growing on the tree trunk. The slugs climb down the tree trunk in the early morning to hide and repeat the cycle.
In the ecosystem, the slugs break down the plant litter into nutrient-rich soil to promote plant growth. They also serve as food for birds and other animals.
Description
The slugs are fluorescent pink in color and about 20 centimeters in length. In an Australian Broadcasting Corporation interview, New South Wales National Parks and Wildlife Service Ranger Michael Murphy described the color: "as bright pink as you can imagine, that's how pink they are".
Origins
Triboniophorus aff. graeffei is related but not identical to Triboniophorus graeffei, the red triangle slug. Taxonomists have confirmed the fluorescent pink species' distinction from the red triangle slug. The slug has relatives in New Guinea, New Caledonia, New Zealand, and eastern Africa. These land masses once connected with Australia as the Gondwanaland supercontinent.
A volcanic eruption at Mount Kaputar 17 million years ago created a high-altitude area where these slugs and other invertebrates and plants have lived isolated for millions of years even as the surrounding rainforests of eastern Australia vanished into dry land.
