Communication and Perception
It is not known to what extent sea turtles communicate with one another. They make grunting noises which can be heard by other turtles, and apparently use these vocalizations to locate each other. Visual cues are probably important in identifying other members of their species, and some tactile communication undoubtedly occurs during mating. However, the bulk of communication in this species remains undescribed.
