Tail Luring and Rain Harvesting in Neotropical Bothrops Pitvipers: Implications for the Ecology and Evolution of These Behaviors

We report tail luring and rain‐harvesting in two species of Bothrops pitvipers from the Atlantic Forest of Brazil. Our observations challenge the widely held views that tail luring is largely restricted to juvenile pitvipers, and that rain‐harvesting is an adaptation evolved by vipers to cope with life in water‐limited environments.
