Animation Short: Preying Behavior

At the beginning of the animation, the `food chain' phenomenon of a small underwater ecosystem is displayed: various species of colorful `pacifist' fishes are happily feeding on floating plankton (food particles) while a ferocious predator fish is stalking a prey fish, hoping to devour it. The remainder of the animation demonstrates the hunting behavior of the predator and the evasive behavior of the prey. We see the greedy predator chasing after each prey until the prey is in close proximity, at which point the predator opens its mouth and vigorously sucks in the prey. Moreover, we can see the five reddish prey fish of the same species forming a school in an attempt to escape from the predator while the predator is eating other prey. When the still hungry predator finally approaches the school, the little `fugitives' scatter in terror and the school breaks into smaller schools. At the end of the animation, the satiated predator wanders away leaving one lucky survivor. Fig. gif shows a still from this animation clip.
