Phrynocephalus
''Phrynocephalus'' is a genus which includes 36 species of small and medium-sized Agamidae, agamid lizards, commonly called toadhead agamas or toad-headed agamas, that inhabit open arid and semiarid environments of Asia and Eastern Europe. The systematics of this genus are very complicated with many controversial points of view about the unclear Phylogenetics, phylogeny of this group. All representatives of this genus have adopted the so-called "sit and wait" hunting strategy, and they actively use visual orientation when watching for food. In general, the ecological niche and role of ''Phrynocephalus'' species in lizard communities of arid environments of Asia are poorly studied but seem to be similar to those of ''Phrynosoma, Cophosaurus, Holbrookia, Side-blotched lizard, Uta'', and ''Sceloporus'' in the New World, as well as ''Thorny dragon, Moloch'' in Australia. Species The following 36 species are recognized as being valid. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phrynocephalus Arabicus
Arabian toad-headed agama (''Phrynocephalus arabicus'') is a species of agamid lizard found in Saudi Arabia, Qatar, United Arab Emirates, Oman, Iran, and Jordan. Description It is one of 34 recognized species within the genus ''Phrynocephalus''. In 2014, Melkinov split ''P. arabicus'' into 4 distinct species: ''arabicus sensu stricto'', ''nejdensis'', ''macropeltis'', and ''ahvazicus''. To date only '' P. ahvazicus'' has been formally recognized as a separate species. ''P. arabicus sensu stricto'' is recognizable by its unique tail coloration. It has a white coloration on the underside of the tail with a black tip. When the animal is alerted the whole last quarter of the tail becomes black. ''P. arabicus'' also has a relatively long tail and a pointed snout. Adults may attain a snout-to-vent length (SVL) of 51 mm (2 in) and weigh 4.08g on average. Behavior This species is diurnal.

Phrynocephalus Ananjevae
Natalie's toad-headed agama (''Phrynocephalus ananjevae'') is a species of agamid lizard endemic to the Zagros Mountains in Iran. The specific epithet honours Natalia Ananjeva of the Zoological Institute in St. Petersburg, Russia for her contribution to herpetological research of the family Agamidae and ''Phrynocephalus'' in particular.

Thorny Dragon
The thorny devil (''Moloch horridus''), also known Common name, commonly as the mountain devil, thorny lizard, thorny dragon, and moloch, is a species of lizard in the Family (biology), family Agamidae. The species is Endemism, endemic to Australia. It is the monotypic taxon, sole species in the genus ''Moloch''. It grows up to in total length (including tail), with females generally larger than males. Taxonomy The thorny devil was first species description, described by the biologist John Edward Gray in 1841. While it is the only species contained in the genus ''Moloch'', many taxonomists suspect another species might remain to be found in the wild. The thorny devil is only distantly related to the morphology (biology), morphologically similar North American horned lizards of the genus ''Phrynosoma''. This similarity is usually thought of as an example of convergent evolution. The names given to this lizard reflect its appearance: the two large horned scales on its head comp ...

Agamidae
Agamidae is a family containing 582 species in 64 genera of iguanian lizards indigenous to Africa, Asia, Australia, and a few locations in Southern Europe. Many species are commonly called dragons or dragon lizards. Overview Phylogenetically, they may be sister to the Iguanidae, and have similar appearances. Agamids usually have well-developed, strong legs. Their tails cannot be shed and regenerated like those of geckos (and several other families such as skinks), though a certain amount of regeneration is observed in some. Many agamid species are capable of limited change of their colours to regulate their body temperature. In some species, males are more brightly coloured than females, and colours play a part in signaling and reproductive behaviours. Although agamids generally inhabit warm environments, ranging from hot deserts to tropical rainforests, at least one species, the mountain dragon, is found in cooler regions. They are particularly diverse in Australia. This gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
