Some of these animals have developed special adaptations to protect themselves from hostile environments and deadly predators. In fact, some of the most effective defenses these animals have is their thick, strong skin, which helps them resist physical damage, extreme temperatures, and even some diseases. It will protect the life of thick skin by saving it from its wild environment, not to mention making the body resistant to environmental stresses – hot or extremely cold – and warding off threats of predation. Here is a list of the most difficult animals in the wild:. From the sun-shielding skin of the hippopotamus to the armor-like scales of the crocodile, each of the species on this list shows strength with its skin to survive. Let’s go see these amazing creatures and understand why they are so amazing in their hard exoskeletons.
10 animals with the toughest skin in nature
Animal with the thickest skin
Crocodile
Crocodiles are the symbol of tough, protective skin. The skin is armored with scabs (bony, keratin-covered plates) and osteoderms (bony structures under the skin), making it almost impenetrable. This tough skin provides good protection against predators and even human interference, as it can withstand bullets. However, it is robust and flexible. Therefore, it allows rapid water movement while playing its armor role to cover critical body organs. This skin formation allows crocodiles to exist in hostile environments as other animals pose less of a threat to them, despite the crocodile’s enormous size.
Elephant
The size and strength of the elephant are known to many; but so is the thickness of their skin. Over the body it is an inch thick, but over the ears it is quite a bit thinner. Deep wrinkles in the folds make the structure so water traps in it keeping the elephant cool in very hot savannah climates. The skin protects the elephant from the sun and biting insects. Elephants bathe mainly in mud; which protects the elephants against sunburn and parasites. Their skin is quite protective against predators but can be damaged by humans or other wild animals.
Rhinoceros
The rhinos have some of the toughest animal skins with an average thickness of two inches in some areas. The layers of their skin made of collagen make their skin tough against predators like a lion or a crocodile. The biggest challenge is that the rhino takes their mud bath to maintain it as another protective shield as their skin tends to burn from the sun. It lays down a protective layer that helps keep out insects and sunlight. Despite their thick skin, rhinos can still suffer from parasites and external injuries, so they often rely on mutual relationships with birds, which help clean their skin.
Sperm whale
Another tough-skinned animal is the sperm whale. It needs this skin to defend itself against the harsh conditions of the sea. In fact, the skin is up to 13.5 inches thick, especially on the back, head and tail. This is how it protects the whales from the sharp teeth of predators such as sharks and killer whales. However, the sperm whale’s skin is not as thick on its abdomen, so it relies on its ability to turn its hard back against any incoming threat. Despite their size and strength, sperm whales encounter few predators due to their formidable size and thick skin.
Bison
Bison are the largest land animals in North America, and their skin is quite thick to withstand extreme weather conditions. Their skin is a critical adaptation that allows them to survive the freezing cold American plains winters. It keeps them warm and hardens in the cold. The thick fur of bison also protects them from environmental hazards such as the biting insects during warmer seasons. In addition, their thick skin helps them protect themselves from predators such as wolves or mountain lions. Their muscular body builds up their strong skin, which allows them to withstand most attacks from nature.
Whale shark
The whale shark is the largest fish in the world. Sometimes the skin has been recorded to be about 4 inches thick. Covered in denticles (tiny tooth-like structures), this skin provides protection from physical damage and parasites as it swims through the ocean. Whale sharks have very few predators, but their thick, tough skin helps protect them from those who might get too close, such as large sharks. The denticle-covered skin also reduces drag when they swim, allowing them to move more efficiently through the water. Whale sharks are gentle giants, and their tough skin is one of their most important defenses against the harsh oceanic environment.
Armadillo
Probably one of the most famous animals that have a tough outer covering are armadillos. The bony plates, called a carapace, protect their bodies from predators. The armadillo can roll into a tight ball by using its hard, armor-like shell to defend itself. Its skin under the armor is still thick and strong and offers some flexibility, so it can twist and maneuver to get away from predators. Although very effective, armor also acts as insulation, keeping armadillos warm in their environment when temperatures are extremely cold and cool when temperatures are extreme. Despite their small size, armadillos are very well protected due to their special skin.
Camel
The camel is fully adapted to the harsh desert environment. The thick skin helps protect it from the extreme heat of the desert during the day and cold temperatures at night. Camels have extra layers of skin around their knees and chest, which protects them from burns when lying on the hot desert sand. In addition, their thick skin is resistant to dehydration – very important when water is scarce. The combination of camel skin along with a hump of fat makes them resistant to the hardships they face in the desert environment.
Honey Badger
These honey badgers come in such a small size but have very strong skin. The skin thickness of a honey badger is about a quarter of an inch. That’s amazing for an animal of such a small size. It also prevents lions or hyenas from predators. Honey badgers can stretch their skin to prevent attackers from holding them. The flexibility of honey badgers, combined with their aggressiveness and sharp claws, enables them to wriggle out of the jaws of their attackers or to fight the attackers. It is their thick skin that saves them from predators.
Hippo
A hippopotamus has two of the thickest skins in the animal kingdom with a thickness of about two inches. This thick skin performs several functions, such as offering protection from predators and the hot African sun. Hippo skin secretes a natural pink substance that prevents sunburn while submerged for long hours. Their skin also protects the hippo from physical harm as hippos become very aggressive when defending their territory. Although they have few natural predators due to their size and strength, their tough skin ensures they remain safe in the wild.
