Research Shows Male Guppies Reproduce Even After Death
June 12, 2013
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 10 months after they die, living on as stored sperm in females, who have much longer life spans 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.
