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. Taxonomy In the famous ''10th edition of Systema Naturae'' of 1758, Carl Linnaeus cited descriptions by Albertus Seba and by Laurens Theodorus Gr ...

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] |
Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between 129,000 and c. 11,700 years ago. The late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (commonly known as the Middle Pleistocene). The beginning of the Late Pleistocene is the transition between the end of the Penultimate Glacial Period and the beginning of the Last Interglacial around 130,000 years ago (corresponding with the beginning of Marine Isotope Stage 5). The Late Pleistocene ends with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a p ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Laurens Theodorus Gronovius
Laurens Theodoor Gronovius (1 June 1730 – 8 August 1777), also known as Laurentius Theodorus Gronovius or as Laurens Theodoor Gronow, was a Dutch naturalist born in Leiden. He was the son of botanist Jan Frederik Gronovius (1686–1762). Throughout his lifetime Gronovius amassed an extensive collection of zoological and botanical specimens. He is especially remembered for his work in the field of ichthyology, where he played a significant role in the classification of fishes. In 1754 he published the treatise , in which he described over 200 species of fish. He is also credited with developing a technique for preservation of fish skins. Today, a number of these preserved specimens are kept in the Natural History Museum in London. In 1762 he published the second edition of his father's ''Flora Virginica exhibens Plantas''. In 1763 he was elected a Fellow of the Royal Society. Legacy Gronovius is commemorated in the scientific name of a species of lizard, '' Scelotes gronovii' ...

Albertus Seba
Albertus or Albert Seba (May 12, 1665, Etzel near Friedeburg – May 2, 1736, Amsterdam) was a Dutch pharmacist, zoologist, and collector. Seba accumulated one of the largest cabinets of curiosities in the Netherlands during his time. He sold one of his cabinets in 1717 to Peter the Great of Russia. His later collections were auctioned after his death. He published descriptions of his collections in a lavishly illustrated 4 volume . His early work on taxonomy and natural history influenced Linnaeus. Career Born in Etzel, Seba moved to Amsterdam as an apprentice and, around 1700, opened a pharmacy near the harbour. Seba asked sailors and ship surgeons to bring exotic plants and animal products he could use for preparing drugs. Seba also started to collect snakes, birds, insects, shells, and lizards in his house. From 1711, he delivered various medicines to the Russian court in Saint Petersburg and sometimes accepted fresh ginger as payment. Seba promoted his collection to ...

Anaconda And Squamata Skeletons
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 ...

Constriction
Constriction is a method used by several snake species to kill or subdue their prey. Although some species of venomous and mildly venomous snakes do use constriction to subdue their prey, most snakes which use constriction lack venom. The snake strikes at its prey and holds on, pulling the prey into its coils or, in the case of very large prey, pulling itself onto the prey. The snake then wraps one or two loops around the prey, forming a constriction coil. The snake monitors the prey's heartbeat to ascertain it is dead. This can be a physically demanding and potentially dangerous procedure for the snake, because its metabolism is accelerated up to sevenfold and it becomes vulnerable to attack by another predator. Contrary to myth, the snake does not generally crush the prey, or break its bones. However, wild anacondas have been observed to cause broken bones in large prey. Also contrary to prior belief, the snake does not suffocate the victim. Instead, a study of boa cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venom
Venom or zootoxin is a type of toxin produced by an animal that is actively delivered through a wound by means of a bite, sting, or similar action. The toxin is delivered through a specially evolved ''venom apparatus'', such as fangs or a stinger, in a process called ''envenomation''. Venom is often distinguished from ''poison'', which is a toxin that is passively delivered by being ingested, inhaled, or absorbed through the skin, and ''toxungen'', which is actively transferred to the external surface of another animal via a physical delivery mechanism. Venom has evolved in terrestrial and marine environments and in a wide variety of animals: both predators and prey, and both vertebrates and invertebrates. Venoms kill through the action of at least four major classes of toxin, namely necrosis, necrotoxins and cytotoxins, which kill cells; neurotoxins, which affect nervous systems; myotoxins, which damage muscles; and Hemotoxin, haemotoxins, which disrupt Thrombus, blood clotti ...
