A recent publication details how a female hybrid cichlid, in this case a cross between a female Pundamilia pundamilia and a male Neochromis omnicaeruleus, developed male reproductive organs and self-fertilized. While very rare, self-fertilization does happen among vertebrate species. The hybrid cichlid was the offspring of two somewhat closely related Lake Victoria Basin species. This female went on to have a total of 14 different broods while isolated. Of all those broods only 17 offspring reached maturity, 2 males and 15 females. The results of testing on all the fish in this study are found on the Royal Society Publishing website.
