List Of Largest Snakes
The largest living snakes in the world, measured either by length or by weight, are various members of the Boidae and Pythonidae families. They include anacondas, Python (genus), pythons and boa constrictors, which are all non-venomous Constriction, constrictors. The longest venomous snake, with a length up to , is the king cobra, while contesters for the heaviest title include the Gaboon viper and the Eastern diamondback rattlesnake. All of these three species reach a maximum mass in the range of . There are fourteen or fifteen living snake species that clearly have a maximum mass of at least , as shown in the table below. Whether the number is fourteen or fifteen depends on whether a DNA analysis reported in 2024 results in the recognition of the northern green anaconda ("''Eunectes akayima''", listed in row 1b below) as a species distinct from the ordinary (southern) green anaconda (''Eunectes murinus''). These include all species that reach a length of at least . There are also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, althoug ...

Theodore Roosevelt
Theodore Roosevelt Jr. (October 27, 1858 – January 6, 1919), also known as Teddy or T.R., was the 26th president of the United States, serving from 1901 to 1909. Roosevelt previously was involved in New York (state), New York politics, including serving as the state's List of governors of New York, 33rd governor for two years.

Northern Green Anaconda
The northern green anaconda (''Eunectes akayima'') is a disputed Boidae, boa species found in northern South America and the Caribbean island of Trinidad. It is closely related to ''Eunectes murinus'', the (southern) green anaconda, from which it was claimed to be genetically distinct in 2024. It is one of the List of largest snakes, heaviest and longest snakes in the world, with one specimen reported by a newspaper to have been long. Like all boas, it is a venom, non-venomous Constriction, constrictor. ''E. akayima'' is estimated to have diverged from its closest relative between 5 and 20 million years ago, originally separated by the Vaupés Arch. Today, specimens of ''E. akayima'' are known from the Orinoco basin and surrounding regions, ranging from Ecuador to Trinidad. Its range is still mostly separate from that of ''E. murinus'', although they partially overlap around French Guiana, with no clear geographical barrier. While allegedly separated through mitochondrial DNA ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eunectes Murinus Distribution Map
Anacondas or water boas are a group of large boas of the genus ''Eunectes''. They are a semiaquatic group of snakes found in tropical South America. Three to five extant and one extinct species are currently recognized, including one of the largest snakes in the world, ''E. murinus'', the green anaconda. Description Although the name applies to a group of snakes, it is often used to refer only to one species, in particular, the common or green anaconda (''Eunectes murinus''), which is the largest snake in the world by weight, and the second longest after the reticulated python. Origin The recent fossil record of ''Eunectes'' is relatively sparse compared to other vertebrates and other genera of snakes. The fossil record of this group is effected by an artifact called the Pull of the Recent. Fossils of recent ancestors are not known, so the living species 'pull' the historical range of the genus to the present. Etymology The name ''Eunectes'' is derived from . The Sout ...

Reticulated Python
The reticulated python (''Malayopython reticulatus'') is a Pythonidae, python species native to South Asia, South and Southeast Asia. It is the world's List of largest snakes, longest snake, and the list of largest snakes, third heaviest snake. It is a non-venomous Constriction, constrictor and an excellent swimmer that has been reported far out at sea. It has colonized many small islands within its range. Because of its wide distribution, it is listed as least concern on the IUCN Red List. In several countries in its range, it is hunted for its skin, for use in traditional medicine, and for sale as pets. Due to this, it is one of the most economically important reptiles worldwide. In very rare cases, reticulated pythons killed and swallowed adult humans. Taxonomy The reticulated python was first described in 1801 by German naturalist Johann Gottlob Theaenus Schneider, who described two zoological specimens held by the Göttingen Museum in 1801 that differed slightly in colour and ...

Python Bivittatus
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 males ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doctor Of Philosophy
A Doctor of Philosophy (PhD, DPhil; or ) is a terminal degree that usually denotes the highest level of academic achievement in a given discipline and is awarded following a course of Postgraduate education, graduate study and original research. The name of the degree is most often abbreviated PhD (or, at times, as Ph.D. in North American English, North America), pronounced as three separate letters ( ). The University of Oxford uses the alternative abbreviation "DPhil". PhDs are awarded for programs across the whole breadth of academic fields. Since it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and, in some cases, defend their work before a panel of other experts in the field. In many fields, the completion of a PhD is typically required for employment as a university professor, researcher, or scientist. Definition In the context o ...

Eunectes Murinus
The green anaconda (''Eunectes murinus''), also known as the giant anaconda, emerald anaconda, common anaconda, common water boa, or southern green anaconda, is a semi-aquatic Boinae, boa species found in South America and the Caribbean island of Trinidad. It is the List of largest snakes, largest, heaviest, and second longest (after the reticulated python) snake in the world. No subspecies are currently recognized, but there are two different species that have the name of the Green Anaconda which are the Northern Green Anaconda and Southern Green Anaconda. Like all boas, it is a venom, non-venomous Constriction, constrictor. The term "anaconda" often refers to this species, though the term could also apply to other members of the genus ''Eunectes''. Fossils of the snake date back to the Late Pleistocene in the Gruta do Urso locality.
