evidence: The giant northern anaconda had eluded documentation until recently when it was stumbled upon during a National Geographic expedition. [...] The newly discovered species of anaconda has been named Eunectes akayima. It’s different from the one we already knew, called Eunectes murinus. Akayima means ‘big snake’ in an indigenous language from northern South America. [...] Anacondas, those big water snakes, are a good example. There are four known types, with the biggest one called the Green Anaconda, living in most of South America. But there are also smaller ones with different names like the Beni Anaconda and Dark Spotted Anaconda.
