A lizard tail shed by autotomy An autotomised skink tail exhibiting continued movement The conspicuous change in the tail pattern of this marbled gecko indicates regeneration after autotomy. Some lizards, [4] [5] salamanders [6] [7] [8] and tuatara [9] when caught by the tail will shed part of it in attempting to escape.
Slender glass lizard (Ophisaurus attenuatus)Ophisaurus (from the Greek 'snake-lizard') is a genus of superficially snake-like legless lizards in the subfamily Anguinae.Known as joint snakes, glass snakes, or glass lizards, they are so-named because their tails are easily broken; like many lizards, they have the ability to deter predation by dropping off part of the tail, which can break into ...
The pieces of tail will continue to move once broken off. Two common beliefs are that the pieces of broken tail can grow into new lizards or rejoin into a new tail. [12] In a 1989 study, 79% of the specimens in the population area had broken tails. [10] It is hard to find a slender glass lizard that has its entire tail.
Skull diagram in top down and side-on views. Unlike the vast majority of lizards, the tuatara has a complete lower temporal bar closing the lower temporal fenestra (an opening of the skull behind the eye socket), caused by the fusion of the quadrate/quadratojugal (which are fused into a single element in adult tuatara) and the jugal bones of ...
For the side-blotched lizard, limbs serve as an anti-predatory defense – their ability to survive without a tail allows them to escape predation after being caught. While this defense mechanism can be advantageous, the loss of a tail can also negatively impacts a lizard’s survival and reproduction.
Like many other lizards, including the frilled lizard and basilisk, the collared lizard can run on its hind legs, and is a relatively fast sprinter. Record speeds have been around 16 miles per hour (26 km/h), much slower than the world record for lizards (21.5 mph or 34.6 km/h) attained by the larger-bodied Costa Rican spiny-tailed iguana ...
Tiliqua rugosa, most commonly known as the shingleback skink, stumptail skink or bobtail lizard, is a short-tailed, slow-moving species of blue-tongued skink (genus Tiliqua) endemic to Australia. It is commonly known as the shingleback or sleepy lizard .
These lizards are often distinguishable from snakes on the basis of one or more of the following characteristics: possessing eyelids, possessing external ear openings, lack of broad belly scales, notched rather than forked tongue, having two more-or-less-equal lungs, and/or having a very long tail (while snakes have a long body and short tail).
