Mammalia - Monotremes

Image and Info: http://www.neiu.edu/~mtaban/Mammals.html

Monotremes are mammals that lay eggs, are warm-blooded, and produce milk to feed their young. They are the most primitive mammals. They only live in Australia and New Guinea. They only have one hole for urinary waste, reproduction, and solid waste. Monotreme means "one-holed."
