Etymology: Ancient Greek writers called a certain sea snail "nēritēs," and the name carried a sea-god's flavor with it. The Greek word is linked to Nereus, the old sea deity, though the snail's name is a separate ancient word that later became attached to his circle of sea-related figures. The Greek term passed into Latin as "nērīta," and modern taxonomists took it as the scientific name for the genus Nerita, the group of snails that gave the family Neritidae its name. English speakers borrowed the word from that scientific usage rather than from everyday speech, so the snail's common name is a taxonomic label that became a household term among aquarium keepers. Its present meaning is therefore a case of a Latinized scientific name moving outward into the hobby world, where the small, patterned shells are prized for grazing algae off tank glass.
