Terrifying Snake With A Spider Tail.

The spider-tailed horned viper, which uses its tail as bait to lure birds as prey.

This utterly terrifying-looking creature is called the spider-tailed horned viper, and for good reason. The venomous snake, native to Iran, has a tail that looks like a spider — and it uses the eerie appendage as bait to lure in birds, which it then devours.

Thanks to Animal Planet for bringing our attention to this snake's bizarre, unsettlingly realistic spider tail. It so closely resembles a spider.
