Killer whales - the only marine mammals that populate the entire world's oceans from the Arctic to the Antarctic. Just depending on the amount of feed, the population density varies. Hold the toothed whales flocks, allowing them to more easily provide food, which mainly consists of gregarious species.
Killer whales, circling around the jamb, ultrasound bubbles knock the fish into a tight ball - begins a feast for the whole pack. But there are animals who prefer meat diet. This is usually a small group of two to ten individuals. These animals foraged birds, dolphins, seals and small whales.
The power and grace of killer whales caused mixed feelings in others delight, beauty, danger and certain superstitious fear, fueled by such films as "Death among the icebergs." I've seen many times these animals in nature, and I can say that in fact the killer whales are trying to avoid contact with the person.
