This image shows a ventral view of a female preserved crayfish. Unlike in males
where the first and second pair of swimmerets are stout, forward facing
structures, all of the swimmerets (1) of the female are soft and somewhat
translucent. On the female crayfish observe the opening to the seminal
receptacle (2), which receives sperm from the male, as well as the openings to the
oviducts (3), which are located at the bases of the third pairs of walking legs
These openings have been expanded to make them more visible.
