The eyes of the hammerhead sharks confer greater anterior binocular overlaps and enhanced stereovision due to their positioning on the distal tips of the cephalofoil.

Edit Hook


“These findings indicate that the anterior binocular overlap has increased concomitant with the lateral expansion of the hammerheads. With head expansion the eyes of the scalloped hammerhead and winghead sharks have migrated into a more anterior position on the distal tips of the cephalofoil and facilitates the enhanced binocular overlap.” McComb et al. 2009: 4016)
