Solution

The strange-looking coelacanth is one of the oldest species of fish in the world. the coelacanth is potentially critical to our understanding of how creatures walked out of the sea and onto the earth. That's because it has four fins, or lobes, sticking out of its body like legs. Even more fascinating, it moves those fins in an alternating fashion that resembles walking or trotting.
