Most of the animals have some or the other trick up their sleeve to deal with the predator in case they are caught. While some animals shed the non-vital parts of their body to escape (autotomy), others go to the extent of ejecting their internal organs to disgust the predator (evisceration). Not all animals rely on such unusual techniques though. Some species, for instance, are armed with a protective covering--an armor--to save them from the predator's clutches.
When we speak of armored animals, the turtle with its thick shell is likely to be the first species to come to your mind. While the shell definitely happens to be the best example of animal armor, it is not the only example of the same. In fact, it is just one of the different types of armors that animals use to defend themselves against predators with others being spikes and spines, bony plates, thick skin, etc.
While armor-like skin, protective coloration, mimicry, speed and agility, herd behavior, etc., have helped the species survive predation by other members of the animal kingdom, none of these seem to be of much use when it comes to human onslaught. Will these animals ever evolve to survive humans? They will have to because survival in the end is all about evolving.
