One of the hard truths of evolution is that it's an arms race. Every time something evolves to exploit a niche, something else evolves to compete with it.

The evolution of such creatures as the mudskipper and the lungfish, who could escape their aquatic predators by heaving themselves into the inhospitable environment known as dry land, seemed an insurmountable barrier. Eventually, however, the walking oscar evolved, a streamlined wading fish capable of picking its way along the beach and, in extreme cases, running down its startled prey on foot.

The sight of an entire school of walking oscars out for a jog is one of the most magnificent--and arguably most surreal--in the animal kingdom.
