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!
Airline safety may get superjumbo lift
Airline safety may get superjumbo lift A new double-decker jet is being built which will
hold 650 passengers. The plane is being built with new
technological safety features, such as an onboard electronic map
library which will replace the pile of paper maps that pilots now
use. Pilot visibility will also be improved by locating the cockpit
closer to the ground. Pilots will also have a display showing the
orientation of the nose gear. Fully loaded, the plane will weigh
540,000 kilograms. DECEMBER 4, 2000
