Hares and rabbits are closely related animals, however there are some key differences between them. Hares are typically larger than rabbits, and typically have longer legs and ears. Hares also tend to be more solitary animals, while rabbits live in groups. In addition, hares are born with fur, and their eyes open, while rabbits are born blind and without fur. Hares are also better adapted to running long distances, while rabbits are better adapted for short sprints.
