Plural of dorsal; fins or structures located on the back of an animal, or referring to back-positioned body parts.
From Latin 'dorsalis' meaning 'of the back,' derived from 'dorsum' (back). The plural form adds the standard English '-s' ending to indicate multiple instances of this anatomical feature.
Fish dorsals are like nature's stabilizers—they help prevent the fish from rolling sideways in water, functioning almost like a boat's keel but on the animal's back instead of underneath it.
