THE BEHAVIOR AND SENSORY PHYSIOLOGY OF SHARKS.
Abstract
Research emphasized experimental studies on the hearing and visual functions of sharks, concentrating for the most part on the lemon shark, Negaprion brevirostris. Field, as well as laboratory, studies were undertaken. The major findings were: (1) the lemon shark (and other species studied in the field) has keen hearing ability below approximately 1000Hz; above that point hearing ability decreases very rapidly; (2) the species also perceives some facet of particle displacement within a sound field; (3) certain types of sounds are extremely attractive to free-ranging sharks, while others are not; and, (4) various visual functions (e.g., dark-adaptation) of the lemon shark provide evidence of very sensitive vision in the species, while additional morphological and physiological evidence (e.g., CFF, dark- and light-adapted spectral sensitivities) demonstrates that this species has a 'duplex' retina.
