A scientific name suffix or term indicating ribbed or ridged structure, often used in biological nomenclature for species with ribbed characteristics.
From Latin costatus meaning 'ribbed,' used in Linnaean scientific naming to describe organisms with prominent ribs or ridge patterns in their anatomy or shells.
When biologists name a clam or shell 'costata,' they're literally saying 'the ribbed one' in Latin—the scientific naming system lets you read physical descriptions right in the organism's name.
