Communication and Perception
Heaviside’s dolphins communicate visually, as dolphins have exceptional underwater vision. They also use tactile communication, swimming near other individuals and rubbing against one another to build affiliative relationships. Acoustically, they are able to communicate through a series of whistles and clicks ranging between 1.5 and 11.0 KHz. They communicate chemically by releasing pheromones from pores in their anal glands. Heaviside’s dolphins also rely heavily on echolocation to perceive their surroundings.
