Predators possess usually good senses to find their prey and special abilities to trap the prey. Predatory birds, for example, had an outstanding eyesight and sometimes hearing, for the case of the owls while other predators, like many species of mammals, have a very high sense of smell that helps them locate prey. Many predators are very fast, and use their speed to help capture their prey, some are fastest runners, fast fliers and fast swimmers.
As water is cooled from 4 to 0, its density "decreases." Density is the amount of substance per a specific volume. So, if the water cools it's density decreases, but as the temperature rises it's density will increase because liquid to a gas and a gas has a high density then a liquid.
Hope this helps.
