Goanna Head 2
A goanna is any one of several species of lizards of the genus '' Varanus'' found in Australia and Southeast Asia. Around 70 species of ''Varanus'' are known, 25 of which are found in Australia. This varied group of carnivorous reptiles ranges greatly in size and fills several ecological niches. The goanna features prominently in Aboriginal mythology and Australian folklore. Being predatory lizards, goannas are often quite large, or at least bulky, with sharp teeth and claws. The largest is the perentie (''V. giganteus''), which can grow over in length. Not all goannas are so large; pygmy goannas may be smaller than the arm of an adult human. The smallest of these, the short-tailed monitor (''V. brevicauda''), reaches only in length. They survive on smaller prey, such as insects and mice. Goannas combine predatory and scavenging behaviours. They prey on any animal they can catch that is small enough to eat whole. They have been blamed by farmers for the death of sheep, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iguana
''Iguana'' (, ) is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described in 1768 by Austrian naturalist Josephus Nicolaus Laurenti in his book ''Specimen Medicum, Exhibens Synopsin Reptilium Emendatam cum Experimentis circa Venena''. Two species are placed in the genus, the green iguana, which is widespread throughout its range and a popular pet, and the Lesser Antillean iguana, which is native to the Lesser Antilles. Genetic analysis indicates that the green iguana may comprise a complex of multiple species, some of which have been recently described, but the Reptile Database considers all of these as subspecies of the green iguana. The word "iguana" is derived from the original Taino name for the species, ''iwana''. In addition to the two species in the genus ''Iguana'', several other related genera in the same family have common names of the species including the word "ig ...

Black-headed Monitor
The black-headed monitor or black-tailed monitor (''Varanus tristis'') is a relatively small species of monitor lizards native to Australia. It is occasionally also called the mournful monitor, freckled monitor (''Varanus tristis orientalis'') or the racehorse monitor, a name it shares with the Gould's monitor due to their exceptional speed. It is placed in the subgenus ''Odatria''. Nomenclature Its specific name, ''tristis'', means "sad", in reference to the completely black colouration of ''V. t. tristis'' populations around Perth. Distribution This is the most widespread monitor species in Australia, occurring throughout the mainland and even on some northern islands such as Magnetic Island Magnetic Island ( Wulguru: Yunbenun) is an island offshore from the city of Townsville, Queensland, Australia. This mountainous island in Cleveland Bay has effectively become a suburb of Townsville, with 2,335 permanent residents. The islan .... It is only absent in the southernm ...

Mangrove Monitor
The mangrove monitor, mangrove goanna, or Western Pacific monitor lizard (''Varanus indicus'') is a member of the monitor lizard family with a large distribution from northern Australia and New Guinea to the Moluccas and Solomon Islands. It grows to lengths of . Names It is known as wbl yb in the Kalam language of Papua New Guinea. Taxonomy The mangrove monitor was first described by the French herpetologist François Marie Daudin in 1802. Daudin's original holotype of a subadult specimen was collected on Ambon, Indonesia, and has since disappeared from the museum in Paris. Daudin's original name for the species was ''Tupinambis indicus'', an appellation it would carry for 100 years until being renamed as a ''Varanus''. The generic name ''Varanus'' is derived from the Arabic word ''waral'' (ورل), which translates to English as "monitor." Its specific name, ''indicus'', is Latin for the country of India, but in this instance it relates to Indonesia or the East Indies, where ...

Spiny-tailed Monitor
The spiny-tailed monitor (''Varanus acanthurus''), also known as the Australian spiny-tailed monitor, the ridge-tailed monitor the Ackie's dwarf monitor, and colloquially simply ackie monitor, is an Australian species of lizard belonging to the genus of monitor lizards (''Varanus''). Description The spiny-tailed monitor, a somewhat small monitor lizard, can attain a total length of up to 70 cm (27 in), although there are unconfirmed reports of wild individuals growing up to 34 inches. The tail is about 1.3-2.3 times as long as the head and body combined. The upper side is a rich, dark brown and painted with bright-yellowish to cream spots, which often enclose a few dark scales. Its tail is round in section and features very spinose scales. There are 70-115 scales around the middle of the body. The spiny-tailed monitor is distinguished from the similar-looking species '' V. baritji'' and '' V. primordius'' by the presence of pale longitudinal stripes on the neck. Dist ...

Mertens' Water Monitor
Mertens' water monitor (''Varanus mertensi''), also called Common name, commonly Mertens's water monitor, and often misspelled Mertin's water monitor, is a species of lizard in the Family (biology), family Varanidae. The species is Endemism, endemic to northern Australia, and is a wide-ranging, actively foraging, opportunistic predator of aquatic and Riparian zone, riparian habitats. It is named after German herpetologist Robert Mertens. Description ''Varanus mertensi'' grows to a total length (including tail) of about . It is dark brown to black above, with many cream to yellow spots. The underparts are paler – white to yellowish – with grey mottling on the throat and blue-grey bars on the chest. The tail is strongly compressed laterally, with a high median dorsal keel, and is about 1.5 times the length of head and body. Distribution and habitat Mertens' water monitor is found in coastal and inland waters across much of northern Australia, from the Kimberley (Western Aust ...

Sand Goanna
The sand goanna (''Varanus gouldii'') is a species of large Australian monitor lizard, also known as Gould's monitor, sand monitor, or racehorse goanna. Taxonomy John Edward Gray described the species in 1838 as ''Hydrosaurus gouldii'', noting the source of the type specimen as "New Holland" and distinguishing the new varanid by "two yellow streaks on the sides of the neck" and small flat scales at the orbits. An earlier description, ''Tupinambis endrachtensis'' Péron, F. 1807, was determined as likely to refer to this animal, but the epithet ''gouldii'' was conserved and a new specimen designated as the type. This neotype was obtained in 1997 at the near coastal Western Australian suburb of Karrakatta, and placed with the British Museum of Natural History. The decision of a nomenclatural commission (ICZN) was to issue an opinion suppressing the earlier names, ''Tupinambis endrachtensis'' and ''Hydrosaurus ocellarius'' Blyth, 1868, that were unsatisfactory to some who had comm ...

Lace Monitor
The lace monitor or tree goanna (''Varanus varius'') is a member of the monitor lizard family native to eastern Australia. A large lizard, it can reach in total length and in weight. The lace monitor is considered to be a least-concern species according to the International Union for Conservation of Nature. Taxonomy John White, the surgeon-general of New South Wales, described this species as the variegated lizard (''Lacerta varia'') in 1790. George Shaw reported that several specimens were taken back to England. French naturalist François Marie Daudin gave it the name ''Tupinambis variegatus'' in 1802, and noted two forms. German naturalist Blasius Merrem established the genus '' Varanus'' in 1820, with ''V. varius'' as the first mentioned member set as its type species by John Edward Gray in 1827. French zoologists André Marie Constant Duméril and Gabriel Bibron described two specimens in 1836, one in their possession and one from the collection of English zoologist Th ...

Perentie
The perentie (''Varanus giganteus'') is the largest monitor lizard or goanna native to Australia. It is one of the largest living lizards on earth, after the Komodo dragon, Asian water monitor, crocodile monitor, and intersecting by size with Nile 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 ...

Cape Of Good Hope
The Cape of Good Hope ( af, Kaap die Goeie Hoop ) ;''Kaap'' in isolation: pt, Cabo da Boa Esperança is a rocky headland on the Atlantic coast of the Cape Peninsula in South Africa. A common misconception is that the Cape of Good Hope is the southern tip of Africa, based on the misbelief that the Cape was the dividing point between the Atlantic and Indian oceans, and have nothing to do with north or south. In fact, by looking at a map, the southernmost point of Africa is Cape Agulhas about to the east-southeast. The currents of the two oceans meet at the point where the warm-water Agulhas current meets the cold-water Benguela current and turns back on itself. That oceanic meeting point fluctuates between Cape Agulhas and Cape Point (about east of the Cape of Good Hope). When following the western side of the African coastline from the equator, however, the Cape of Good Hope marks the point where a ship begins to travel more eastward than southward. Thus, the first mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leguaan
The Nile monitor (''Varanus niloticus'') is a large member of the monitor family (Varanidae) found throughout most of Sub-Saharan Africa and along the Nile, with invasive populations in North America. The population 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. Portik, V. de Buffrenil, I Ineich, E Greenbaum, S.O. Kolokotronis and E.R. Hekkala. 2016.
