Ichnotropis Microlepidota
''Ichnotropis microlepidota'' is a species of African lizard in the family Lacertidae. It is commonly called Marx's rough-scaled lizard and is largely found in Angola, Africa. ''I. microlepidota'' is a terrestrial lizard and was first discovered at the foot of Mount Moco. Description ''I. microlepidota'' is a medium-sized lizard with a slender body, long tail, and well developed legs. Most of the specimens found are less than long in snout–to-vent lengt(SVL)and share common characteristics of the genus ''Ichnotropis''. Branch, Bill (1998). ''Field Guide to Snakes and other Reptiles of Southern Africa''. Third Revised edition. Cape Town, South Africa: Struik Publishers. . (Genus ''Ichnotropis'', pp. 160–162). Identification of ''Ichnotropis'' includes the following: *Cylindrical tail without lateral fringe *Toes without serrated or fringed edge *Smooth or tubular lamellae under toes *Subocular scales bordering lip *No collar present * Keeled or overlapping dorsal sc ...

Keeled Scales
Keeled scales refer to reptile scales that, rather than being smooth, have a ridge down the center that may or may not extend to the tip of the scale, Campbell, J. A., Lamar, W. W. (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 870 pp. 1,500 plates. . making them rough to the touch. According to Street's (1979) description of European lizards and snakes, in those that have keeled scales the keels are usually stronger in male specimens and are consistently arranged according to the species of reptiles, even though many others do not have them. With European lizards, the dorsal scales are usually well keeled, while those on the flanks are more weakly keeled and those on the belly smooth. Street, D. (1979). ''The Reptiles of Northern and Central Europe''. London: B.T. Batsford Ltd. 268 pp. . Non-European lizards such as ''Sphaerodactylus macrolepis'' also display keeled scales. Klauber (1997), describes how the keels on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of Angola
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...

Endemic Fauna Of Angola
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous (ecology)
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...

Melierax Metabates
The dark chanting goshawk (''Melierax metabates'') is a bird of prey in the family Accipitridae which is found across much of sub-Saharan Africa and southern Arabia, with an isolated and declining population in southern Morocco. Description The dark chanting goshawk is a medium-sized, bulky hawk with an upright stance. The head, breast and upperparts are essentially dark grey, while the underparts, other than the breast, are white, finely barred with black. The wing primaries are black, and the tail has broad black and white bars. The cere and the long legs are orange-red. The female is, on average, larger than the male, weighing up to 840g to the male's maximum weight of 700g. Juveniles tend to have browner plumage reminiscent in colour and pattern to a buzzard '' Buteo spp'' but with the broad winged, long tailed silhouette of an accipiter.

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insectivorous
A robber fly eating a hoverfly An insectivore is a carnivorous animal or plant that eats insects. An alternative term is entomophage, which can also refer to the human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory. At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each other remain in the order Eulipotyphla. Although individually small, insects exist in enormous numbers. Insects make up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
