Their hearing and sight are very good

The hearing range of a beluga whale is far wider than that of a person. People can hear between 0.02 and 20 kHz, but belugas have a hearing range of 1.2 to 120 kHz. Imagine the variety of noises a beluga hears right now! The squeaks from our rubber Zodiac boats are one collection of noises they may be certain of hearing. These squeaks seem to attract them, along with tourists' often off-key singing, and they frequently stop over to say hello. The belugas are musical creatures and have shown a lot of interest in listening to cellist Rob Knaggs and singing tourists. They might be amused and show their adorable smiles.

Additionally, these pure white whales have superb vision both within and outside of the sea. You can bet they are gazing at you if you believe they are! Occasionally, they'll bring their young to the area and push them up to the surface so they may see a person for the first time. The eye of a beluga is very well-suited for aquatic vision. The nearsightedness that develops as a result of light rays' refraction (bending) when they travel from water to air is corrected in the air by specific characteristics of the lens and cornea.

Rod and cone cells can be seen in beluga retinas, suggesting that they may be able to perceive in both strong and low light. The absence of short wave-length sensitive visual pigments in belugas' cone cells, like in other whales, suggests that their ability to see color is less developed than that of other land animals. An oily, jelly-like mucus is secreted by glands in the inner corners of the eye sockets, lubricating the eyes and clearing away dust. This coating that resembles tears may help shield the eyes from contagious organisms.
