It is rare to spot snakes in Ecuador, no matter where you visit. Almost every snake in Ecuador would rather flee than bite a human.
The majority of snakes are not poisonous, but there are poisonous species, such as the fer-de-lance. In the mangrove forest you can find boa constrictors, and anacondas dwell in Ecuador's jungle. If you see a snake on a beach, be wary; sea snakes in Ecuador are venomous.
