Research shows male guppies reproduce even after death

(University of California - Riverside) Performing experiments in a river in Trinidad, evolutionary biologist David Reznick at the University of California, Riverside and colleagues have found that male guppies -- small freshwater fish -- continue to reproduce for at least ten months after they die, living on as stored sperm in females, who have much longer lifespans than males. While it is well known that guppies store sperm, Reznick and his team had never before thought of the extent of the storage.
