Animal species that exhibit long gestation periods, give birth to relatively large offspring, and maintain population numbers close to the habitat carrying capacity are called K-selected species.
In nature, a given habitat contains sufficient resources such as food, water, etc. to support a maximum possible number of biological species, beyond which no further growth is possible. It is termed as nature's carrying capacity for that species in the habitat.
MacArthur and Wilson proposed that there are two life-history strategies i.e. K-selected and r-selected. K-selected species exhibit a proportionately stable population that gives rise to a low number of offspring which tend to be very large. For example the African elephant is included among K-selected species.
