Size and shape of Animals on land

The size of animals has important consequences for their shape

Body size is the most obvious and one of the most important characteristics of an animal, impacting many parts of its life and its evolution. Although evolution may guide animals to different sizes, shapes, or ecological niches—as we will see it is the ultimately the laws of physics that limit biological processes of an animal and how that animal interacts with the environment.

In the video above we will explore how size and shape are linked in terrestrial species.
