Adult fleas live off the blood of animals and are very difficult to kill. They have hard bodies that make them difficult to 'squish'. Fleas can jump distances of up to 1 metre (3.2 feet). A female flea can lay between 20-30 eggs in one day and she can continue laying that many eggs for between 6 and 9 months. If she lives for 9 months she'll have produced 8,000 eggs. If half of these fleas are females and start laying eggs, this will result in about 500 eggs per day being laid or 15,000 eggs per month!
Weather warning
Weather warning Fossilized coral from Indonesia, which has been
dated as 125,000 years old, may help climatologists determine
whether El Nino is a normal blip in climate change or an alarming
consequence of human-induced climate change. Results so far suggest
that human activity over the past 100 years has dramatically
changed the world's climate. 9 OCTOBER 1999, P. 37-39
