Good observation. A spike in population implies a recent change in the organism or its environment. Since most multicellular organisms cannot evolve that quickly, it's more likely that there was a change in the environment which this organism was able to take advantage of. I doubt that their numbers are spiking because "they are bale to bypass death".
