how big do anacondas get in the amazon

Quick Scoop

Anacondas in the Amazon usually grow to about 16 to 20 feet, and exceptional individuals can reach around 30 feet or more. The green anaconda is the species most people mean, and it is the heaviest snake in the world, with some recorded specimens weighing over 550 pounds.

How big they get

• Typical adults: about 5 to 6 meters, or 16 to 20 feet.

• Large recorded specimens: up to about 9 meters, or 30 feet.

• Rare extreme reports: some sources describe Amazon specimens around 10 meters, but those are unusual and not the norm.

In plain English

If you spot an anaconda in the Amazon, it is far more likely to be in the 16 to 20 foot range than at the extreme upper end. Females also tend to grow larger than males.

TL;DR: Most Amazon anacondas are huge already, but the really giant ones are rare; think 16 to 20 feet commonly, with record-size snakes reaching around 30 feet.
