Yesterday was the Science Fair. I did my science fair project on monkeys, I learned that the smallest monkey is a Pygmy Marmoset and the biggest monkey is a Mandrill. From other people's science fair projects I learned that goats have a slit shape for a pupil and that octopi have beaks and their beaks are made out of the same stuff as our fingernails. I also learned that hyperthyroidism is when all the parts of their body speeds up and it usually happens to older cats.
