A new snake species, the northern green anaconda, sits on a riverbank in the Amazon's Orinoco basin. “The size of these magnificent creatures was incredible," Fry said in a news release earlier ...
• The green anaconda is the largest (most massive) extant snake. The silhouette is scaled to 5.21 metres (17.1 ft) which was the longest measured and published in a study by Jesús Antonio Rivas that measured hundreds of anacondas. [2] There are reports of longer anacondas, but these reports have been questioned. [3] [4] [5]
Sexual size dimorphism in Eunectes is the opposite of most other vertebrates. Females are larger than males in most snakes, and green anacondas have one of the most extreme size differences, where females average roughly 32 kg (70 lb) and males average only around 7 kg (15 lb).
The longest venomous snake is the king cobra (Ophiophagus hannah), with lengths (recorded in captivity) of up to 5.7 m (19 ft) and a weight of up to 12.7 kg (28 lb). [53] It is also the largest elapid. The second-longest venomous snake in the world is possibly the African black mamba (Dendroaspis polylepis), which
The green anaconda is the world's heaviest and one of the world's longest snakes, reaching a length of up to 5.21 m (17 ft 1 in) long. [11] More typical mature specimens reportedly can range up to 5 m (16 ft 5 in), with adult females, with a mean length of about 4.6 m (15 ft 1 in), being generally much larger than the males, which average ...
This is a list of extant snakes, given by their common names. Note that the snakes are grouped by name, and in some cases the grouping may have no scientific basis. Contents:
The new species, described in the journal Diversity, diverged from the previously known southern green anaconda about 10 million years ago, differing genetically from it by 5.5 per cent.
The Indian rat snake (Ptyas mucosa) is also very large with maximum sizes of up to 3.7 m (12 ft), making it the second-largest species in the genus Ptyas. [61] [62] The Tiger rat snake (Spilotes pullatus), which usually grows to about 3 m (10 ft), has been reported to reach up to 4.2 m (14 ft), ranking it among the largest colubrids. [63]
