Elephants are the largest land animals on Earth, and they're one of the most unique-looking animals, too. With their characteristic long noses, or trunks; large, floppy ears; and wide, thick legs, there is no other animal with a similar physique.Most experts recognize two species of elephant: the Asian elephant (Elephas maximus) and the African elephant (Loxodonta africana), who live on separate continents and have many unique features. There are several subspecies that belong to one or the other of these two main species, though experts argue over how many subspecies there are and whether or not they constitute separate species, according to the San Diego Zoo.
Camels live in deserts, where it is hot and dry. Camels have adapted and found ways to help them survive in deserts. They have a thick coat of hair that protects them from the heat in the day, and keeps them warm at night. Their large feet spreads their weight on the sand when they are walking. When there is food and water, a camel can eat and drink large amounts of it and store it as fat in the hump. Then, when there is no food or water, the camel uses the fat for energy, and the hump becomes small and soft. A camel’s waste contains very little water. Even the water from the camel’s breath flows back into its mouth. The camels have bushy eyebrows that don't let the sand go in their eyes in a sandstorm. It has a long slender neck in order to reach high leaves such as palm trees, and rubbery patches on the belly and knees to protect the skin when kneeling and sitting on the hot sand. These form after five years of age.
