Longest sperm in nature

The longest sperm in the animal kingdom, does not belong to the longest or biggest animal, but to a tiny fruit fly with the Latin name Drosophila bifurca. Each uncoiled sperm is up to 2-inches (5cm) long, around 1000 times longer than a human sperm, and 20 times longer than its own body.
