Schaukell
Schaukell, also known as the Schaukell effect, is a phenomenon observed in the behavior of certain types of fish, particularly those that exhibit schooling behavior. This effect is named after the German ichthyologist and herpetologist, Dr. Karl Schaukel, who first described it in the early 20th century. The Schaukell effect refers to the tendency of fish to align their bodies with the direction of their school's movement, even when the school is turning or changing direction. This alignment is thought to be a result of the fish's ability to sense the movement of their neighbors and adjust their own movement accordingly. The Schaukell effect is an important aspect of fish behavior and has been studied extensively in the field of ethology. It is believed to play a role in the coordination of schooling behavior and the overall movement of fish schools. The Schaukell effect is also thought to be an important factor in the survival of fish, as it allows them to move quickly and efficiently through the water, avoiding predators and finding food.
