The mugger crocodile is a very strong swimmer that uses its tail and hind feet to move forward, change direction and go under the water. Its belly touches the ground at the bottom of waterbodies and on land. During the hot dry season, it walks over land at night to find better wetlands. It spends most of the day under the water. During the cold season it basks on riverbanks and they tolerate one another during this period. They are more aggressive during the mating season.
