Come face-to-face with 150 of the world's scariest killer creatures, from the lion and great white shark to the tarantula, anaconda snake, golden eagle, vampire bat, and even the fierce ant! The ebook profiles every kind of animal--mammals, reptiles, birds, fish, insects, and arachnids. Chapters are arranged according to how these dangerous predators kill. Do they use jaws and claws, venom, stings, traps, tricks and cunning, or mass invasion? With more than 200 spectacular photos in the ebook, every page has a stunning image of the animal in action, with data files giving a visual e-guide to its size, distribution, diet, and habitat, as well as a rating of its "scare factor." Each profile features bite-size text that will appeal to all readers. Discover key facts about how the animal lives (is it solitary or a pack animal?), intriguing anatomy (the platypus is famously one of the few venomous mammals, but did you know that the venom comes from the hind leg on the males only?), and of course, their method of attack (such as chasing prey to exhaustion, launching an ambush, or paralyzing with poison). Further fascinating facts can also be found in the reference section, including deadly defense, family trees, toxins, and prehistoric deadly creatures that are no more.
