Eunectes Beniensis
''Eunectes beniensis'' is a boa species known only from the northeastern parts of Bolivia. Its common names, the Bolivian anaconda and Beni anaconda, are derived from the geographic location of its native habitat: the Beni area of Bolivia. Like all boas, it is nonvenomous. Description ''Eunectes beniensis'' is a species of boa, reaching between in length and can weigh up to . It was initially believed to be the result of hybridization between the green (''Eunectes murinus'') and yellow anaconda (''Eunectes notaeus''), but was later determined to be a distinct species. Its taxonomic status is unclear due to lack of information and the similarity in appearance to ''Eunectes notaeus''. It is closely related to ''Eunectes notaeus'' and ''Eunectes deschauenseei ''Eunectes deschauenseei'', commonly known as the dark-spotted anaconda or De Schauensee's anaconda, is a species of snake in the subfamily Boinae of the family Boidae. The species is native to northeastern South America. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

Bolivian River Dolphin
The Bolivian river dolphin (''Inia boliviensis'') is a species of the genus ''Inia''. Taxonomy Bolivian river dolphins were discovered by the Western world in 1832 by French researcher Alcide d'Orbigny. The Bolivian river dolphin was briefly thought to be a subspecies (as ''I. geoffrensis boliviensis)'' of the Amazonian river dolphin, ''Inia geoffrensis'', but differences in body structure and the isolation of the Bolivian river dolphin led to it being classified as its own species in 2012. In a study conducted in 2015, it was also noted that any gene flow between ''I. geoffrensis'' (downstream) and ''I. boliviensis'' (upstream) would be a one way path flowing from upstream to downstream due to the Teotônio waterfall between them. Despite any gene flow, these populations would also remain morphologically different from each other due to the differences in the environment in which they reside. Differences in seasonal water depth and speed would result in morphologically different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of Bolivia
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 ...

Snakes Of South America
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, 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 have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently 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, although this rule is not universal (see Amphisbaenia, Dibamida ...

Eunectes
''Eunectes'' is a genus of boas found in tropical South America commonly called anacondas. They are a semiaquatic group of snakes and include one of the largest snakes in the world, '' E. murinus'', the green anaconda. Four species are currently recognized. Origin The recent fossil record of ''Eunectes'' is relatives sparse compared to other vertebrates and other genera of snakes. The fossil record of the 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 grc, εὐνήκτης, eunēktēs, good swimmer. Distribution and habitat Found in tropical South America from Ecuador, Brazil, Colombia and Venezuela south to Argentina. Feeding All four species are aquatic snakes that prey on other aquatic animals, including fish, river fowl, and caiman. Videos exist of anacondas preying on domesti ...

Phys
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (. ...

Yellow Anaconda
The yellow anaconda (''Eunectes notaeus''), also known as the Paraguayan anaconda, is a boa species endemic to southern South America. It is one of the largest snakes in the world but smaller than its close relative, the green anaconda. No subspecies are currently recognized. Like all boas and pythons, it is non-venomous and kills its prey by constriction. Etymology The Neo-Latin specific name ''notaeus'' derives from grc, νωταίος, nōtaios, dorsal ( is a poetic form of /). In distinguishing his new species ''Eunectes notaeus'' from ''Eunectes murinus'', Edward Drinker Cope stated, "Dorsal scales are larger and in fewer rows." Description Adults grow to an average of in total length. Females are generally larger than males, and have been reported up to in length. They commonly weigh , but specimens weighing more than have been observed. The color pattern consists of a yellow, golden-tan or greenish-yellow ground color overlaid with a series of black or dark brow ...

Green Anaconda
The green anaconda (''Eunectes murinus''), also known as the giant Emerald anaconda, common anaconda, common water boa or sucuri, is a boa species found in South America. It is the heaviest and one of the longest known extant snake species. Like all boas, it is a non-venomous 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. Etymology The green anaconda's specific name is derived from the Latin ', meaning 'of mice', for being thought to prey on mice. Description The green anaconda is the world's heaviest and one of the world's longest snakes, reaching a length of up to long. More typical mature specimens reportedly can range up to , with adult females, with a mean length of about , being generally much larger than the males, which average around .
