sentence: Otters are long and slim animals with four short legs that can be longer than a meter.
sentences_after: They usually stay on all four legs, but they can stand up as well but they are expert swimmers and spend a lot of time in water. They have a thick fur coat that keeps them warm even in freezing water. Their fur is often brown at the top, and lighter on the bottom of the Otter. They eat meat and hunt for fish and small animals, so they have sharp claws and teeth that allow them to catch prey, then eat them. Their thick and long tail helps them steer while swimming underwater.
