What the heck is a Zip? If, like me, you are a graduate of The University of Akron, you already know the answer. I worked five seasons as a student equipment manager for the U of A football team during the late 1970s. That job helped me earn a degree without accruing any student loan debt. Nada. Zero. Zip. But what is a Zip?
We heard that question from the fans at every college stadium we played in across the country. The answer was obvious once you saw Zippy, our school mascot. A Zip is a kangaroo—an Akron, Ohio variety. For a time, the school’s modern rally phrase was “Fear the Roo.” Huh? A kangaroo mascot? To get some history, go to Zippy’s web site at: uakron.edu/zippy.
Once you learn more about kangaroos, you’ll understand why the creature is a wonderful mascot for a sports team. Kangaroos are strong, agile, and fast. They have keen vision and a superb sense of hearing. Any athlete in search of glory in his or her sport of choice would love to embody the traits of this amazing creature from the down under continent of Australia.
Fully grown red kangaroos use their powerful hind legs to move at speeds of more than 35 miles per hour. They bound in leaps almost 6 feet high that measure up to 25 feet long per hop. In comparison, big jackrabbits in Arizona can jump 5 to 10 feet per hop. How far can you jump in a single hop?
Most young readers probably already know that kangaroos are different in many ways. Kangaroos are marsupial mammals. Humans and tigers and monkeys and elephants and horses and bats are placental mammals. Like all mammals, marsupials are hairy and warm blooded. The mothers produce milk for their young. But marsupials have an outside pouch where their young grow and develop.
A baby kangaroo is called a Joey. The Joey is hairless and only the size of a Lima bean when it is born. The tiny Joey actually must climb from the birth canal into its mother’s pouch. During six months in the mother’s pouch, the Joey will grow 2,000 times bigger than its size at birth.
More than 60 kinds of kangaroos live on Earth today. The musky rat kangaroo is the smallest. A full grown adult weighs less than a pound. Big red roos can weigh up to 175 pounds. Powerful hind legs give the kangaroo its hopping power. But how many legs does a kangaroo have? You say four, of course. Nope. Not according to a 2015 research study published in Biology Letters.
The correct answer is five legs, say scientists from Australia’s University of New South Wales. A walking kangaroo actually propels itself with its muscular tail. The tail acts like a fifth leg. The scientists learned that the tail of a walking kangaroo works as hard as our legs work when we walk down the street. No other animal is known to use its tail in this way.
