All anacondas are semi-aquatic spending most of their time in swamps, and slow-moving streams. In fact the first part of all four species names (the generic name) is Eunectes which is derived from Greek for good swimmer. These animals do not maneuver well on land but in the water they maneuver very well. They all have eyes and nostrils set high on their heads enabling them to remain almost completely submerged while waiting for prey to approach. Int his video, find how giant anaconda attacked a cow. This is one of the rarest videos, where such a giant anaconda has been spotted. And guess what? It can swallow a cow even.
