3. Snakes
Snakes contain both rods and cones, but they’re not able to see the same color spectrum as humans. What is truly fascinating about snakes is their ability to see infrared colors, meaning they can see heat energy in their surroundings. Their ability to see infrared colored is due to their eyes, which are capable of seeing longer wavelengths than humanly possible. This is vital for hunting as their able to see the heat energy and movement of their prey.
