This is not to suggest that all r-selected species are invasive. Plenty of r-selected species are beneficial in their native lands.

The “strategic intent” is to flood the habitat with progeny so that, regardless of predation or mortality, at least some of the progeny will survive to reproduce. Organisms that are r-selected have short life spans, are generally small, quick to mature and waste a lot of energy. Typical examples of r-strategists are. salmon ; corals ; insects

Among the fishes, most, like the salmon, are r-selected. Some species will even inadvertently eat their own young if they are not immediately dispersed, but a few species, such as the cichlids, are K-selected and provide prolonged care and protection of the In biology, this is called r-K selection: in an r-situation, organisms will invest in quick reproduction, in a K-situation they will rather invest in prolonged development and long life.
