Watch Adaptive Function Of Form: The Beauty Of Ugly

One of Biology's key themes is that form, or body structure, in living things fits each one's function. This helps explain the "beauty," or adaptive success, of so-called "ugly" animals in nature. If we see ugly animals in light of how well they have adapted to their niches or environments, we appreciate how "deformity" gives each a better fitness for survival. Watch the parade of diverse adaptations in mammals, birds, reptiles, and fish that defy our preconceptions of ugliness.
