Yellow underside of a starfish. It really makes me wonder why sea creatures are so colorful despite the fact that they are mostly underwater. It turns out, according to an article that I read, that communication signals, mating, camouflage, territory and other factors are used for color information and fine spatial information to encode species identity.

And at the rate the ocean degradation is happening, these shallow water colorful sea creatures won’t have much protection from mostly humans who them more harm and damage. So please, put back these starfish and other sea creatures in the water if you are done taking their photos. As much as possible, leave them where they belong: to the sea.
