Let's do an experiment. First, we'll take your basic group of crabs crawling around in the sea. Next we'll find an isolated island in the South Pacific with a variety of ecosystems. Finally, we'll sprinkle our crabs around the island and let them survive and reproduce in their new environments. After say, a few million years, voila! We'll have a mind-blowing variety of crabs.
Nobody started this experiment on the island of Espiritu Santo several million years ago, but they may as well have. A 2006 biodiversity expedition found about 10,000 species new to science, including this astonishing parade of well-dressed crabs. I have fallen instantly in love with these little guys.
