Facts: Down and Derby

  • Green iguanas have a long, solid tail that provides balance when they are climbing. This tail has another use: as a weapon.

  • Although chameleons change color more dramatically, green iguanas also have the ability to change slightly from their greenish-gray color. The brightest color is found on juvenile males and also on females; the adult male possesses a more muted green hue.

  • Native to the Gal├ípagos Islands, the marine iguana's black coloration enables it to warm up after swimming in the cold waters of the ocean.

  • Just as we adapt to different climates, the adaptation of iguanas vary through their species. Green iguanas, unlike black iguanas, thrive in the high trees in the tropical rain forest. Other iguanas live comfortably in the hot, arid desert.

  • Because they are highly territorial, iguanas kept as pets tend to be happier and healthier when caged separately from other animals.

  • Out of 10 million acres of farmland in Michigan, about 3.3 million of those acres are protected through preservation agreements intended to maintain their use in agricultural.

  • Farms play a key role in the state of Michigan: as of 2010 Census Bureau figures, Michigan's 9.8 million residents were outnumbered by the number of acres used for agriculture in the state.

  • Alopecia, a disease causing low red blood cell production, is a serious health problem for calves, and many do not make it past six months. From birth, calves with alopecia are distinguished by protruding eyes and tongues in addition to tightly curled hair, or no hair at all.

  • According to the American Pet Products Association, in 2011 Americans spent a whopping $50 billion on their pets, and the APPA estimates that the total will be even higher in 2012.
