Extant animals size

[SameerluvAnimals]

The green anaconda is the world's heaviest snake, reaching 5.2 m (17.1 ft) in length. More typical mature specimens range up to 5 m (16.4 ft), with the females, at around a mean length of 4.6 m (15.1 ft), being generally much larger in adulthood than the male, which averages around 3 m (9.8 ft). Weights are less well studied, though will reportedly range from 30 to 70 kg (66 to 154 lb) in an average-range adult. It is also one of the world's longest snakes. Although it is slightly shorter than the reticulated python, it is far more robust. The bulk of a 4.5 m (15 ft) green anaconda would be comparable to a 7.4 m (24.2 ft) reticulated python.

The green anaconda is probably the heaviest extant species of snake or squamate in the world, perhaps only rivaled by the Komodo dragon. Reports of 9 - 12 m (30-40 ft) anacondas exist but such claims have never been scientifically verified.  A $50,000 cash reward is offered for anyone who can catch an anaconda 30 ft (9.1 m) or longer, but the prize has not been claimed yet. The longest and heaviest verified specimen encountered by Dr. Jesús Antonio Rivas, who had examined thousands of anacondas, was a female measuring 5.2 m (17.1 ft) long and weigh 97.5 kg.
