The word "zoopeiral" is a rare term that refers to the spiral shape of certain animal organs, particularly the cochlea in mammals' ears. The word is pronounced /zuːˈpɛɪrəl/ in IPA phonetic transcription, with the stress on the second syllable. The spelling of this word is derived from "zoo-" meaning "animal" and "-peira" meaning "spiral" in Greek. While uncommon, it is a useful term for describing specific anatomical features in the study of biology and zoology.
