Rattlesnakes IFC_01We use our senses to learn about the world around us—we can see a rattlesnake in the grass, hear the sound of its rattle, and feel its dry, scaly skin. Rattlesnakes use their senses to gather information too, but some of their senses are very different from ours.
Rattlesnakes’ sense of sight isn’t as good as ours is—they can only see well at short distances of less than 15 feet. But their other senses more than make up for their sight. They use their tongues to smell their prey, and they can feel the vibrations in the ground to tell how far away it is. Rattlesnakes use their jawbones to hear—when they rest their jaws on the ground, the vibrations they pick up are carried through their jawbones to their ears.
Not only do rattlesnakes use their senses differently from us, but they use other senses that we don’t. Rattlesnakes and their relatives have small pitted openings in their faces help them sense heat, so they can find their way to warm-blooded prey even in the dark. Can you imagine having senses like a rattlesnake? How would you use them?
