However, it is represented by only one living species: the tuatara (Sphenodon punctatus), a superficially lizard-like reptile native to New Zealand. [ 5 ] [ 6 ] Lepidosauria is a monophyletic group (i.e. a clade ), containing all descendants of the last common ancestor of squamates and rhynchocephalians. [ 7 ]
The interactions between the gecko's feet and the climbing surface are stronger than simple surface area effects. On its feet, the gecko has many microscopic hairs, or setae (singular seta), that increase the Van der Waals forces - the distance-dependent attraction between atoms or molecules - between its feet and the surface.
Swelling of the skin Elephantiasis , often incorrectly called elephantitis , is the enlargement and hardening of limbs or body parts due to tissue swelling ( edema ). [ 1 ] [ 2 ] It is characterised by edema, hypertrophy , and fibrosis of skin and subcutaneous tissues, due to obstruction of lymphatic vessels ( lymphedema ). [ 2 ]
Burton's legless lizard (Lialis burtonis) is a species of lizard in the family Pygopodidae. The species lacks forelegs and has only rudimentary hind legs. [2] Pygopodid lizards are also referred to as "legless lizards", [3] "flap-footed lizards" [4] and "snake-lizards". [5] This species is native to Australia and Papua New Guinea. [6]
Mature bearded dragons can reach a total length of around 60 cm (24 in), or two feet, with the tail accounting for more than half of that. Some sexual dimorphism is present, as males can be distinguished from females by a wider cloacal opening , a wider tail-base, a larger and more angular head, a more developed beard ( guttural throat-pouch ...
G. kuhli has adaptations to its skin, including flaps on either side of its body, webbed feet, and a flattened tail to allow it to glide over short distances. This gecko has a remarkable camouflage. The flaps of skin along its sides help it blend with tree bark. Often, its eyes are the only way to distinguish it from its surroundings.
Image of common side-blotched lizard. A distinguishing feature of this species is the dark blotch behind the front leg, which is clearly seen in this image. The dark blotch is generally less prominent in females than in this male. The systematics and taxonomy of the widespread and variable lizards of the genus Uta is much disputed.
Amphisbaenia / æ m f ɪ s ˈ b iː n i ə / (called amphisbaenians or worm lizards) is a group of typically legless lizards, [1] comprising over 200 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes.
