Some emus run fast (between 30-35 mph) and other emus run
 slower (between 20-25 mph.) Dingos are the main predators of
 emus and at their absolute fastest can reach speeds of up to 30
 mph. Emus lay between 30-50 eggs a year, but only 20 of those
 eggs will live long enough to mature into their own reproductive
 age.
