Lacking a tail or having the tail removed; used in zoology and botany to describe organisms without tail-like appendages.
From Latin 'ex-' (without) + 'cauda' (tail). The term entered scientific vocabulary in the 17th-18th centuries to precisely describe anatomical variations in plants and animals.
Scientists needed exact words for animal differences, so they combined Latin pieces: 'excaudate' means 'un-tailed.' It's like building scientific LEGO—each piece fits perfectly to describe nature's weird exceptions.
