Star Bright, Star Light
The spiny brittle star is a shining example of how beauty exists even at the tiniest scale. Its disc and five arms glow with a distinct variety of candy colors and patterns. Some species of brittle star even create their own bioluminescence.
The brittle star can intentionally lose an arm when threatened and regrow it completely in a few weeks. It uses its arms to crawl around in a rowing motion, similar to the way a sea turtle moves it flippers. When it wants to turn, it simply changes its lead arm and heads off in a new direction.
