Goldenrod Crab Spider Misumena vatia

This crab spider can change color between white, yellow, pink, and green based on whatever flower it's hunting from, like a tiny sneaky chameleon with eight eyes and killer reflexes. Even more bizarre: if it eats a colored insect, the spider itself can gradually take on that color through its molting cycle—it literally becomes what it eats, visually speaking.

The sideways scuttling movement (which earned them the "crab" nickname) and dramatic color shifts make these tiny hunters pure spectacle. Found across Europe and North America in goldenrod and milkweed patches, females grow to about 10mm while males are half that size. Their visual system is surprisingly sophisticated for such a small predator.
