Photo @tbfrost | Words @paulrosolie | Can you guess what this anaconda ate? Unlike most other species, the green anaconda (Eunectes murinus) can, in a single lifetime, grow through the ranks of secondary, tertiary, and apex predator. That is to say, they go from very small to very large — starting life at just two feet and less than a pound, they can blossom to over twenty feet long, and upwards of three hundred pounds. They are both prey and predator to a vast array of Amazonian taxa - birds, mammals, reptiles, fish etc. Therefore, anacondas are perhaps one of the most influential players in the most biologically competitive terrestrial ecosystem on the planet. But there is still no hard population information on anaconda numbers in the Peruvian Amazon, which makes it impossible to establish a baseline for the species. We have no way to tell if they are thriving or in decline. Over the last ten years in an effort to establish this baseline, my team and I have measured seventy five wild anacondas – but one of the most shocking discoveries thus far has been the anaconda’s temperament: every single individual, even the ones that were too big to catch, (giants that could easily crush a human), chose flight over fight. I decided not to measure the snake in this photo for fear of upsetting her while digesting (snakes can regurgitate their hard won meal if stressed). Instead I watched as @tbfrost moved closer to the large snake, elbows in the mud, to get the shot – it was clear that neither snake nor human was in any kind of danger.
