Drosophila bifurca

Drosophila bifurca is a species of fruit fly. Males of this species are known to have the longest sperm cells of any organism on Earth, an astonishing 5.8 cm long when uncoiled. The cells are mostly tail, and are delivered to the females in tangled coils. In a male's entire life he can only make a few hundred such cells. The other members of the genus Drosophila also make very few, giant sperm cells, with D. bifurca's being the longest.
