As for didactyly, chameleons visibly have five toes on each foot, not two. Some chameleons have a crest of small spikes extending along the spine from the proximal part of the tail to the neck; both the extent and size of the spikes vary between species and individuals. These spikes help break up the definitive outline of the chameleon, which ...
The panther chameleon was first described by French naturalist Georges Cuvier in 1829. [4] Its generic name is derived from the Latin root furci meaning "forked" and refers to the shape of the animal's feet. [6] The specific name pardalis refers to the animals' markings, as it is Latin for "leopard" or "spotted like a panther". [7]

The term is derived from the Greek word δακτυλος (dáktylos) meaning "finger." Sometimes the suffix "-dactylia" is used. The derived adjectives end with "-dactyl" or "-dactylous."
Lizard is the common name used for all squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, [1] ranging across all continents except Antarctica, as well as most oceanic island chains.
The feet in loons [2] and grebes [2] [7] are placed far at the rear of the body - a powerful accommodation to swimming underwater, [7] but a handicap for walking. The snowshoe-like foot of the willow ptarmigan is an adaptation for walking on snow. [1] Because avian forelimbs are wings, many forelimb functions are performed by the bill and ...
Although A. carolinensis is sometimes called an 'American chameleon', true chameleons do not naturally occur in the Americas, and A. carolinensis is not the only lizard currently in its area of distribution capable of changing colour. In contrast, many species of true chameleons display a greater range of color adaptation, though some can ...
Jackson's chameleon (Trioceros jacksonii), also known commonly as Jackson's horned chameleon, the three-horned chameleon, and the Kikuyu three-horned chameleon, is a species of chameleon, a lizard in the family Chamaeleonidae.

Like many other chameleons, the four-horned chameleon has a prehensile tail and single claws on its toes. It usually has four prominent horns, but sometimes two are present with up to four adjacent reduced horns; [4] adults typically grow to a total length (including tail) of 10–14 in (25–36 cm).
