Plasmodium Parasitic Invasion of Host
Plasmodium parasites responsible for Malaria invade red bloods cells to extract nutrients from hemoglobin proteins which over epochs cause red blood cells to rupture.
One can observe the oxygenic efficiency of the host decline until the host reaches a fatal state.
Sharks (predators of all fish types and birds), large fish (predators of smaller fish), small fish (consume seaweed) and birds (evidential mating and consumption of fish) are existent within this artificial life simulation.
Flocking behaviour is evident, sharks will consume periodically when hungry, birds will mate and produce gender-variable offspring.
