Describing an animal or organism that does not have a tail.
The acaudate species of fish are fascinating because they lack a tail.
Acaudate is formed from "a-" (meaning without) and "caudatus" (from Latin, meaning having a tail). The word describes something that is without a tail.
Think of 'without' ('a-') and 'tail' ('caudatus') to remember that 'acaudate' refers to something that lacks a tail.
