Some fish can make electricity. They surround themselves with an electrical field. If anything moves in the field, the fish can feel it. Their electrical fields are able to detect food and their enemies.
The Bear Facts
The Bear Facts Male black bears can weigh up to 360 kilograms
(800 lbs) and are very powerful. Black bears can experience grumpy
moods, especially in spring when they are hungry. In late summer,
bears consume about 20,000 calories per day, which is about five
times their normal feeding rate. They must put on a fat layer of
about 12.7 centimetres (5 inches) to survive the winter. Bears
often spend the winters at the bases of tree stumps, in root
cavities, in trees, in beds of sticks and leaves, and even under
highways! Bears are excellent swimmers and tree climbers, and very
fast runners. SEPTEMBER, 2000
