Chamaeleo
''Chamaeleo'' is a genus of chameleons in the Family (biology), family Chamaeleonidae. Most species of the genus ''Chamaeleo'' are found in sub-Saharan Africa, but a few species are also present in northern Africa, southern Europe, and southern Asia east to India and Sri Lanka. Description Species in the genus ''Chamaeleo'' are slow moving, with independently movable eyes, the ability to change skin colouration, a long tongue, usually a prehensile tail, and special leg adaptations for grasping vegetation. Males are generally larger and more colorful than females. Almost all species have a maximum snout-vent length (SVL) between . Behavior The vast majority of ''Chamaeleo'' species are arboreal and typically found in trees or bushes, but a few species (notably the Namaqua Chameleon) are partially or largely Terrestrial animal, terrestrial. Reproduction The genus ''Chamaeleo'' includes only Oviparity, oviparous species. In captivity With few exceptions, the chameleons most commo ...

Chameleon
Chameleons or chamaeleons (Family (biology), family Chamaeleonidae) are a distinctive and highly specialized clade of Old World lizards with 200 species described as of June 2015. The members of this Family (biology), family are best known for their distinct range of colours, being capable of colour-shifting camouflage. The large number of species in the family exhibit considerable variability in their capacity to change colour. For some, it is more of a shift of brightness (shades of brown); for others, a plethora of colour-combinations (reds, yellows, greens, blues) can be seen. Chameleons are also distinguished by their zygodactylous feet, their prehensility, prehensile tail, their laterally compressed bodies, their head casques, their projectile tongues used for catching prey, their swaying gait, and in some species crests or horns on their brow and snout. Chameleons' eyes are independently mobile, and because of this the chameleon’s brain is constantly analyzing two sepa ...

Veiled Chameleon
The veiled chameleon (''Chamaeleo calyptratus'') is a species of chameleon (family Chamaeleonidae) native to the Arabian Peninsula in Yemen and Saudi Arabia. Other common names include cone-head chameleon, Yemen chameleon, and Yemeni chameleon. They are born pastel green and without their distinctive casques on their head. As they mature, their casque develops along with more vibrant coloring, as well as a dramatic gular fold that will protrude from their throat and chin. They are known for their variable color changes due to a variety of factors, including to show aggression, social status, reproduction, and stress. Female lifespan is around five years while male lifespan is around eight, and they breed a few times a year. Etymology The term 'veiled chameleon' refers to the species ''Chamaeleo calyptratus''. 'Veiled' describes their distinctive casque on the head, resembling a veil. This term highlights the species' unique feature. The generic term 'chameleon' is derived f ...

Bradypodion
''Bradypodion'' (meaning "slow-footed" in Greek) is a genus of chameleons in the family Chamaeleonidae, collectively called South African dwarf chameleons. All species are found in South Africa and most are endemic to this country, but a few can also be found in Eswatini, Lesotho, southernmost Namibia and possibly southernmost Mozambique. They are quite small chameleons where the different species often can be difficult to separate by appearance, although exact location (each species tends to have a rather small distribution) and the intense breeding colours of males are useful for their identification. They are arboreal, but some species are mostly found low in the vegetation. ''Bradypodion'' feed on small invertebrates, especially insects. They rapidly reach sexual maturity, typically at an age between half a year and one year, but sometimes up to two years. Adult males are territorial. It is the only genus of chameleon where females of all species give birth to live youn ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Calumma
''Calumma'' is a genus of chameleons, highly adapted and specialised lizards, in the Family (biology), family Chamaeleonidae. The genus is endemic to the island of Madagascar. One species, formerly known as ''Calumma tigris'' (the Seychelles tiger chameleon), was transferred to the genus ''Archaius'' in 2010, upon the discovery of its closer relation to ''Rieppeleon''—one of several genera referred to collectively as "leaf" or "pygmy" chameleons—rather than to ''Calumma''. The earliest known fossil of the genus is of ''Calumma benovskyi'', from early Miocene Kenya, showing that the genus likely originated on mainland East Africa. The genus includes one of the heaviest and longest chameleon species, the Parson's chameleon (''Calumma parsonii''). Species groups Four species groups are recognised within the genus ''Calumma'' (originally proposed by Frank Glaw, Glaw & Miguel Vences, Vences in 1994), some of which may be only phenetic, while others are phylogenetically supported: ...

Prehensile Tail
A prehensile tail is the tail of an animal that has Adaptation (biology), adapted to grasp or hold objects. Fully Prehensility, prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees. If the tail cannot be used for this it is considered only partially prehensile; such tails are often used to anchor an animal's body to dangle from a branch, or as an aid for climbing. The term ''prehensile'' means "able to grasp" (from the Latin ''prehendere'', to take hold of, to grasp). Evolution One point of interest is the distribution of animals with prehensile tails. The prehensile tail is predominantly a New World adaptation, especially among mammals. Many more animals in South America have prehensile tails than in Africa and Southeast Asia. It has been argued that animals with prehensile tails are more common in South America because the forest there is denser than in Africa or Southeast Asia. In contra ...

Oviparity
Oviparous animals are animals that reproduce by depositing fertilized zygotes outside the body (i.e., by laying or spawning) in metabolically independent incubation organs known as eggs, which nurture the embryo into moving offsprings known as hatchlings with little or no embryonic development within the mother. This is the reproductive method used by most animal species, as opposed to viviparous animals that develop the embryos internally and metabolically dependent on the maternal circulation, until the mother gives birth to live juveniles. Ovoviviparity is a special form of oviparity where the eggs are retained inside the mother (but still metabolically independent), and are carried internally until they hatch and eventually emerge outside as well-developed juveniles similar to viviparous animals. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or f ...

Josephus Nicolaus Laurenti
Josephus Nicolaus Laurenti (4 December 1735, Vienna – 17 February 1805, Vienna) was an Austrian naturalist and zoologist of Italian origin. Laurenti is considered the auctor of the class Reptilia (reptiles) through his authorship of ' (1768) on the poisonous function of reptiles and amphibians. This was an important book in herpetology, defining thirty genera of reptiles; Carl Linnaeus's 10th edition of ''Systema Naturae'' in 1758 defined only ten genera. ''Specimen Medicum'' contains a description of the blind salamander (amphibian): '' Proteus anguinus'', purportedly collected from cave waters in Slovenia (or possibly western Croatia Croatia, officially the Republic of Croatia, is a country in Central Europe, Central and Southeast Europe, on the coast of the Adriatic Sea. It borders Slovenia to the northwest, Hungary to the northeast, Serbia to the east, Bosnia and Herze ...); this description represented one of the first published accounts of a cave animal in the we ...
