Ugly Fish = Better Reproducers?
Studies are conducted on a regular basis into all manner of things, but this one really amused me!
Professor Jonathan Evans (from the Centre for Evolutionary Biology at the University of Western Australia) carried out the study into the reproductive skills of tropical guppies, and the findings are described in the Royal Society journal, Proceedings B.
Apparently, guppies are a good species in which to study this, because “the males engage in two types of reproductive behavior – courtship displays and non-consensual or “sneak” mating”. The study found that the males who performed sneak mating were less pretty, but has faster swimming sperm in comparison to their prettier counterparts.
Although the prettier of the species may get more “action”, they are less able to reproduce; I feel that there is a lesson in there somewhere…
