Like their otariid cousins, the special sensory organs in phocids include the eyes, ears, nose, and vibrissae (whiskers). Like all marine mammals, phocids have quite a challenge to overcome because they have to function in air, in water, in bright light, and in low light.

Indeed, as fully aquatic animals, cetaceans have become superbly adapted to take advantage of the physical properties of water.
