Pygmy Seahorse’s Coral Camouflage
These tiny seahorses match their host coral with almost supernatural precision. Their bodies develop bumps and colors that perfectly copy the coral polyps they live among. Each species of pygmy seahorse tends to live on a specific type of sea fan, and their bodies evolve to match that particular coral’s appearance. Scientists still puzzle over how these seahorses achieve such precise mimicry of their host corals’ textures and colors.
