Shields up! Make your alien impenetrable.

Animals and plants with shields are pretty awesome! Armadillos, for example, have a bony shell that protects them from predators, while turtles have a shell made of both bone and cartilage. Even some insects have shield-like structures, like the ironclad beetle, which has a hardened exoskeleton that can resist being run over by a car! And let’s not forget about plants – some species, like the Roman shield fern, have fronds that resemble shields. Whether it’s for defense or just as a unique adaptation, these shielded creatures and plants are definitely impressive!
