Researcher Rebecca Helm thought she was imagining things when a flash of indigo appeared in a sample of water she collected off the coast of South Africa, according to Grist. It turns out that she had captured a Sapphirina copepod, which she has nicknamed the "sea sapphire." The tiny shrimp sparkles like the blue gem when hit by light at the right angle. The effect is dazzling as one can see from a video of a "sea sapphire" hanging out in a corral reef.
