The Canadian tiger swallowtail caterpillar has one of the neatest defense mechanisms against predators: when the caterpillar senses a bird nearby it quickly inflates the front part of its body, making it resemble a snake's head.
It grows concentric yellow and black rings that look like a giant pair of eyes. The caterpillar also have an osmeterium, an orange, fleshy organ that emits foul-smelling terpenes to repel predators. The combo between the osmeterium and the blow up fake snake head make this butterfly a super neat member of the animal kingdom.
