Final answer:
Certain animals can see infrared and/or ultraviolet rays due to their tetrachromatic vision, which allows them to perceive a wider range of colors than humans.
Step-by-step explanation:
Certain animals can see infrared and/or ultraviolet rays due to their Tetrachromatic vision. Tetrachromatic vision is the ability to perceive a wider range of colors than humans, and it is achieved through the presence of additional types of cone cells in the animal's eyes. Unlike humans, who have three types of cone cells (red, blue, and green), animals with tetrachromatic vision have four or more types of cone cells that respond to different ranges of electromagnetic wavelengths, allowing them to see colors beyond the visible spectrum.
