Nile Monitor
The Nile monitor (''Varanus niloticus'') is a large member of the monitor family (Varanidae) found throughout most of Sub-Saharan Africa, particularly in drier regions, and along the Nile River and its tributaries in East Africa. Additionally, there are modern, invasive populations in North America. The population found in West African forests and savannahs is sometimes recognized as a separate species, the West African Nile monitor (''V. stellatus'').Dowell, S.A, D.M.

Lake Baringo
Lake Baringo is, after Lake Turkana, the most northern of the Kenyan Rift Valley lakes, with a surface area of and an elevation of . The lake is fed by several rivers: the Molo River, Molo, Perkerra River, Perkerra and Ol Arabel. It has no obvious outlet; the waters are assumed to seep through lake sediments into the Fault (geology), faulted volcanic bedrock. It is one of the two freshwater lakes in the Rift Valley in Kenya, the other being Lake Naivasha. See "Kenya designates freshwater lake in Great Rift Valley," aRamsar 2009 - 2002 The lake is in a remote hot and dusty area with over 470 species of birds, occasionally including migrating flamingos. A Goliath heronry is located on a rocky islet in the lake known as Gibraltar. The existence of Lake Baringo was first reported in Europe by Ludwig Krapf and J. Rebmann, German missionaries stationed at Mombasa, about 1850; in J. H. Speke’s map of the Nile sources (1863) Baringo is confused with Kavirondo Gulf of Victoria Nyanza; ...

Perentie
The perentie (''Varanus giganteus'') is a species of monitor lizard. It is one of the largest living lizards on earth, after the Komodo dragon, Asian water monitor, and the crocodile monitor. Found west of the Great Dividing Range in the arid areas of Australia, it is rarely seen because of its shyness and the remoteness of much of its range from human habitation. The species is considered to be a least-concern species according to the International Union for Conservation of Nature. Its status in many Aboriginal cultures is evident in the totemic relationships, and part of the Ngiṉṯaka dreaming, as well as bush tucker. It was a favoured food item among desert Aboriginal tribes, and the fat was used for medicinal and ceremonial purposes. Taxonomy British zoologist John Edward Gray described the perentie in 1845 as ''Hydrosaurus giganteus'', calling it the "gigantic water lizard". George Albert Boulenger moved it to the genus ''Varanus''. Within the monitor genus '' Varanu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Djenné-Djenno
Djenné-Djenno (also Jenne-Jeno; ) is a UNESCO World Heritage Site located in the Niger River Valley in the country of Mali. Literally translated to "ancient Djenné", it is the original site of both Djenné and Mali and is considered to be among the oldest urbanized centers and the best-known archaeological sites in West Africa. This archaeological site is located about from the modern town, and is believed to have been involved in long distance trade and possibly the domestication of African rice. The site is believed to exceed in area; however this is yet to be confirmed with extensive survey work. With the help of archaeological excavations mainly by Roderick and Susan McIntosh, the site is known to have been occupied from 250 BC to 900 AD. Previously, scholars did not believe that advanced trade networks and complex societies developed in West Africa until traders started coming from the north. However, sites such as Djenné-Djenno disprove this, as these tradit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Species Group
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant variety (botany), varieties), which may be a complex ranking but it is not a species complex. In most cases, a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 ...

Panther Chameleon
The panther chameleon (''Furcifer pardalis'') is a species of chameleon found in the eastern and northern parts of Madagascar in a tropical forest biome. Additionally, it has been introduced to Réunion and Mauritius, as well as the state of Florida within the United States. Taxonomy The panther chameleon was first described by French naturalist Georges Cuvier in 1829. Its generic name (''Furcifer'') is derived from the Latin root ''furci'' meaning "forked" and refers to the shape of the animal's feet. The specific name ''pardalis'' refers to the animals' markings, as it is Latin for "leopard" or "spotted like a panther". The English word chameleon (also chamaeleon) derives from Latin ''chamaeleō'', a borrowing of the Ancient Greek χαμαιλέων (''khamailéōn''), a compound of χαμαί (''khamaí'') "on the ground" and λέων (''léōn'') "lion". The Greek word is a calque translating the Akkadian ''nēš qaqqari'', "ground lion". This lends to the common Eng ...

Madagascar Giant Day Gecko
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's fourth largest island, the second-largest island country, and the 46th largest country overall. Its capital and largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife being endemic. The island has a subtropical to tropical maritime climate. Madagascar was first permanently settled during or before the mid-first millennium AD (roughly AD 500 ...

Green Iguana
The green iguana (''Iguana iguana''), also known as the American iguana or the common green iguana, is a large, arboreal, mostly Herbivory, herbivorous species of lizard of the genus ''Iguana''. Usually, this animal is simply called the iguana. The green iguana ranges over a large geographic area; it is native from southern Brazil and Paraguay as far north as Mexico. A herbivore, it has adapted significantly with regard to locomotion and osmoregulation as a result of its diet. It grows to in length from head to tail, although a few specimens have grown more than with bodyweights upward of . Commonly found in captivity as a pet due to its calm disposition and bright colors, it can be very demanding to care for properly. Space requirements and the need for special lighting and heat can prove challenging to the hobbyist. Taxonomy The species was first officially described by Swedish botanist Carl Linnaeus in 1758. Since then, numerous subspecies have been identified, but later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Burmese Python
The Burmese python (''Python bivittatus'') is one of the largest species of snakes. It is native to a large area of Southeast Asia and is listed as Vulnerable on the IUCN Red List. Until 2009, it was considered a subspecies of the Indian python, but is now recognized as a distinct species. It is an invasive species in Florida as a result of the pet trade. Description The Burmese python is a dark-colored non-venomous snake with many brown blotches bordered by black down the back. In the wild, Burmese pythons typically grow to , while specimens of more than are unconfirmed. This species is sexually dimorphic in size; females average only slightly longer, but are considerably heavier and bulkier than the males. For example, length-weight comparisons in captive Burmese pythons for individual females have shown: at length, a specimen weighed , a specimen of just over weighed , a specimen of weighed , and a specimen of weighed . In comparison, length-weight comparisons for ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Argentine Black And White Tegu
The Argentine black and white tegu (''Salvator merianae''), also Common name, commonly known as the Argentine giant tegu, the black and white tegu, the blue tegu, and the huge tegu, is a species of lizards in the Family (biology), family Teiidae. The species is the largest of the "tegu" lizards. It is an omnivorous species, which inhabits the tropical rain forests, savannas, and semideserts of eastern and central South America. It is native to south and southeastern Brazil, Uruguay, eastern Paraguay, Bolivia, and Argentina. Tegu lizards are sometimes kept as pets, being notable for their unusually high intelligence and their ability to be Housebreaking, housebroken. Like other reptiles, tegus go into brumation in autumn when the temperature drops. They exhibit a high level of activity during their wakeful period of the year. They are the only known nonavian reptiles to be partly endothermic. Tegus fill ecological niches similar to those of monitor lizards, but are only distantly ...

Agama Agama
The common agama, red-headed rock agama or rainbow agama (''Agama agama'') is a species of lizard from the family Agamidae found in most of sub-Saharan Africa. To clear up centuries of historical confusion based on Linnaeus and other authors, Wagner et al. designated a neotype (numbered ZFMK 15222) for the species, using a previously described specimen from Cameroon in the collection of the Zoologisches Forschungsmuseum Alexander Koenig in Bonn. The species name was formerly applied to a paraphyletic collection of taxa (a so-called wastebasket); subsequent mitochondrial DNA analysis of various populations indicates they represent separate species.Leaché, A.D. et al. (2009)Phylogeny of the genus ''Agama'' based on mitochondrial DNA sequence data.''Bonner zoologische Beiträge'' 56(4) 273-78. Consequently, three former subspecies '' A. a. africana'', '' A. a. boensis'', and '' A. a. mucosoensis'' are now considered separate species, and ''A. a. savattieri'' is considered synonymou ...

Atlantic Hurricane Season
The Atlantic hurricane season is the period in a year, from June 1 through November 30, when Tropical cyclone, tropical or subtropical cyclones are most likely to form in the North Atlantic Ocean. These dates, adopted by convention, encompass the period in each year when most tropical cyclogenesis occurs in the tropical cyclone basins, basin. Even so, subtropical or tropical cyclogenesis is possible at List of off-season Atlantic hurricanes, any time of the year, and often does occur. Worldwide, a season's climatology, climatological peak activity takes place in late summer, when the difference between air temperature and sea surface temperatures is the greatest. Peak activity in an Atlantic hurricane season happens from late August through September, with a midpoint on September 10. Atlantic tropical and subtropical cyclones that reach tropical storm intensity are Tropical cyclone naming, named from a predetermined list. On average, 14 named storms occur each sea ...
