A whole bundle of Ascaris lumbricoides. With this many, definitely there has to be females to produce that many, and this aggregate may have a majority of females and a few males mixed in. Most cases with only male, the number of round worm submitted is only one.

Actually if we make the picture larger, we can see the head of the Ascaris with its three lips.
