Although dogs and cats live on land and both are easily domesticated, dogs actually have more in common with marine animals than they do with their furry foes. Canines share a lot of similar characteristics with seals, for example, mainly because both the fluffy dogs and baby seals are considered Caniformes (which literally means "dog-like") and come from the same suborder of Carnivorans (unlike cats, which are Feliformes).
