No lascivious copulation, sneaker males, or sperm displacement observed, but cool nonetheless. Thanks Steve! . . . → Read More: Your Friday Cuttlefish

Among fruit flies the longer the reproductive tract of the female the longer the sperm. In tiny crustaceans called ostracods, sperm length can range from several hundred micrometers to several millimeters.

Example: I recently attended the Society of Nematology’s 50th Anniversary meeting, where the plenary topic was….traumatic insemination.
