These colorful shapes look like the work of an artist, but they once belonged to living creatures: green sea urchins. In life, the urchin’s green spines and flesh covered these internal skeletons (called tests), and their intricate detail was hidden from view. The test functions much like our skeleton, providing support and protection for the animal’s systems.
