The term ANIMAL WATER can be solved by the five-letter word OTTER. Otters are semi-aquatic mammals that live in both freshwater and saltwater habitats. They are members of the Mustelidae family, which includes weasels, badgers, and wolverines. Otters have long, slim bodies and short legs, and they are well adapted to their aquatic lifestyle. They have webbed feet, dense fur, and a thick layer of fat that helps them stay warm in cold water. Otters are social animals and often live in large groups.
