Research team sheds light on 'rightie' or 'leftie' behavior in a scale-eating cichlid

Behavioral laterality, or left- or right-handedness, has been reported in many animals, including humans, chimpanzees, toads, rats, mice, and invertebrates such as crustaceans and insects. Now researchers have shed light on the development of behavioral laterality (left-/right-handedness) in a scale-eating cichlid from Africa's Lake Tanganyika.
