The Mcllwraith gecko (Orraya occultus)

Tuesday, July 5th, 2011


We began to wonder if we were at a high enough altitude for leaftails. Of course, the answer to this was to continue further up the gorge. We investigated every eyeshine in hopes of finding something other than ring-tailed geckos.

I detected a pale eyeshine on the flat underside of a boulder approximately 300 feet upstream from our campsite. A feeling of excitement tinged with a little fear of losing sight of the animal washed over me as I approached, concentrating on the small points of light. As I got closer, the eyeshine became stronger and the outline of the animal began to emerge.

This was definitely not a ring-tailed gecko, but rather a very flat, spiny animal that could only be a leaftail. Without delay I grabbed the animal for identification – yes! The first Mcllwraith leaftail found in 15 years and only the fourth specimen ever found! If that was not enough, this specimen had an original tail; all the previous specimens had regenerated tails.

Around the same time, another team member uncovered another specimen. This one clung to a bare rockface hidden within a cavity beneath boulders; it had a regenerated tail and also two partially developed eggs.

This gecko species is extremely gaunt and elongated, almost emaciated in appearance, with a flattened head and body, and long thin limbs. The cervical vertebrae are extremely elongated, resulting in an extraordinarily long, thin neck. This species also differs from other leaftails in possessing three lumbar vertebrae as opposed to two, causing it to be placed in a separate genus. The dorsal surface is covered with spiny tubercles. The original, leaf-shaped tail has tubercles with clusters of two to three pointed spines around its perimeter and more blunt, longitudinally aligned tubercles on its dorsal surface.

The next morning we spent photographing leaftails and other herp species found at the location, before following the creek back to our base camp at Rocky Scrub. We has successfully located and photographed the Mcllwraith leaf-tailed gecko, observed Australia’s longest gecko and two herp species endemic to the Mcllwraith Range, the long-snouted frog and the Coen rainbow skink.

Feet Which Will Go Anywhere

Wednesday, November 17th, 2010


Carrying their heavy shelters around with them, turtles have no need for speed. Their requirement is for powerful legs able to carry the extra weight, and propel them along at a deliberate pace. Most lizards, by comparison scurry through life at a breakneck clip. Generally, they use all four legs in moving about, but several can run on their hind legs, like man. The majority of them rely on swiftness and agility to capture prey or escape enemies. Thus, depending on where they live, they have feet adapted for running across soft sand or over rocks or for climbing trees. Arboreal species have by far the most specialized feet: the chameleons have opposable toes which grasp branches like pincers, the geckos have marvelous clinging pads. The snakes, on the other hand, have learned how to move about without any legs at all.

Pillarlike legs support the weight of the giant Galapagos tortoise, which sometimes weighs 400 pounds or more. While land turtles have developed short thick legs, sometimes with sharp claws for digging, marine turtles have evolved flippers.

Clinging pads on the undersides of a gecko’s toes allow it to scurry easily up trees and smooth walls and even dash across ceilings. The pads, present in most gecko species, consist of a series of plates which are equipped with many tiny hook-like cells.
