Bushmaster (Lachesis muta) - Loreto, Peru.
The Amazon Bushmaster (Lachesis muta) and its close relatives are the largest of the pitvipers in the western hemisphere - and among the largest in the world. Much maligned and misunderstood, these gigantic snakes are reclusive and actually rather timid in most circumstances. They exist in low densities, usually in undisturbed habitat and typically in burrows or beneath tangled root masses. But not all about them is myth. A large, fully aroused Bushmaster merits respect and should be given a wide birth. All in all, Bushmasters are magnificent, world class animals. Río Nanay, Loreto, Peru September 2017.
