But this is actually the cause of the huge number of different species. The main secret lies in the ability of many animals to adapt to eating a specific plant or animal, which few other species are able to eat. These beaks give them a great advantage over other birds with smaller beaks. The fruits and nuts from many trees have evolved with a tough shell to protect them from predators. In turn toucans and parrots developed large strong beaks, which serves as a nutcracker and provides them with many tasty meals.
Every animal has the ability to protect itself from being someone's next meal.
The following are just a few of these unique and often bizarre adaptations. The coloring of some animals acts as protection from their predators. Some butterflies, when they close their wings, look exactly like leaves. Camouflage also works in reverse, helping predators, such as boa constrictors, sneak up on unsuspecting animals and surprise them. The three-toed sloth is born with brown fur, but you would never know this by looking at it.
