K-selection is the opposite of R-selection. While R-selection promotes rapid reproduction with little effort, K-selection promotes putting more effort into reproducing and having a few offspring that have a better chance at survival. K-strategists have offspring that are more dependent on the parent and have a longer juvenile period. The population size of a K-strategist species compared to an R-strategist species is smaller yet more stable. This picture is of a Guinea Pig. Guinea pigs are an example of a K-strategist species. Guinea pig pregnancy lasts for three months and on average, a guinea pig will have two to three pups in a litter.
