There Are Crystal Mirrors Hidden in Scallop Eyes

The video explores the complex visual system of scallops, which have up to 200 telescope-like eyes using mirrors made of guanine crystals to focus light. These eyes have two retinas, allowing scallops to see two images simultaneously. The video also discusses a recent study suggesting sponges, not comb jellies, are the earliest branch on the animal evolutionary tree, based on genomic analysis and statistical filtering.
