The scaly-foot snail is one of the top 10 astounding marine species of the decade (2007-17). Like the kind of bacteria that builds the snail’s shell, this type takes the chemicals in the neighborhood and synthesizes them into grub for the snail, probably a kind of sugar (this bacteria also hasn’t yet been cultured in the lab, so we’re still a bit in the dark here, too).
