Did you know goldfish can see both infrared and ultraviolet light
Goldfish are the only animals that can see both infrared and ultraviolet light. This is because they have four types of cone cells in their eyes, while humans only have three. The extra cone cell allows goldfish to see a wider range of wavelengths, including infrared and ultraviolet. This gives goldfish a significant advantage in the wild, as they can see prey and predators that humans cannot.
