The structure of animals has developed to aid them in surviving in their habitat. These physical features help them to hunt, flee from predators and mate. There are many different types of structures. The prior article discussed the head, neck and body now the adaptations of appendages and tail that serve many functions will be explained.

Arms and hands have evolved to fins or wings. Primates use their hands much as humans. Bats have wings to fly letting them eat millions of insects with each flight. Fish and water mammals like the manatee have fins to propel them through their environment.

The legs of the predators are muscular and heavily boned to take down their prey. The prey animals like the antelope and deer have long, lightly boned legs for fleetness.

Tails are very important in the animal world. They are used for balance essential to the cheetah. Kangaroos not only use their tails for balance in motion but become a third leg for reclining. New world monkeys have a prehensile tail that works like an extra arm. The peacock uses his elaborate tail to attract mates. The scorpion has a poisonous barb at the end of the tail for protection. Marine animals have developed tails fins to for locomotion.

The Milwaukee Public Museum, the Milwaukee County Zoo and walks around Milwaukee will show area residents the uses of these adaptation by the animals.
