Tarantula spiders are among the most feared animals on the planet, and with good reason. Not only are they giants, as spiders go, but they are such stealthy and skilled hunters that no small animal that wanders within their grasp stands a chance at survival. The typical hunting modus operandi for tarantulas is to be patient. They lie in wait for a hapless passerby and then pounce without warning. Because of their size, they can reach 5 inches in length with a 12-inch leg span; tarantulas are able to quickly subdue their prey and crush them with their large fangs. Finally, they shower their victim's body with digestive juices and then lap up the resulting fluid. Delicious!
