Marmoratus makes clones of itself when it self fertilizes, but males do
show up, and mix up the genes suposedly, I have had 2 males show up in my
colony. It is thought males show up during "good times" but the
hermaphrodism is to help this species in hard times because of the harsh

There are two ambystomid salamanders ( tremblays and silvery) that are not
hermaphrodites, but triploid, they are all female, and need to breed with a
male from the ancestral parent species , but the male contributes no genes.
A species of house gecko does this as well, as does the northern redbellyX
finescale dace.
