🎉 Fun Facts
- The Green Anaconda holds the record for the heaviest snake in the world.
- Anacondas can remain underwater for up to 10 minutes without surfacing.
- They have flexible jaws that allow them to swallow prey much larger than their head.
- In some cases, females may cannibalize males after or during mating.
- Despite their fearsome reputation, attacks on humans are extremely rare.
- The word “Anaconda” likely comes from the Tamil word anaikondra (“elephant killer”)—despite no anaconda actually killing elephants.
