78 ALLAH'S ART OF DETAIL
The Striking Detail in Living Things
Capable of Perceiving Electricity
Living things emit electricity as well as heat. It may be diffi-
cult for you to feel this electricity, because air is an insulator. A con-
ductive environment and special equipment are necessary for this
electricity to be felt. Water, a natural conductor, and certain life
forms that live in water and use the electrical currents in their bod-
ies are examples of this. A living thing that can detect electricity in
water and acts according to that sensation has a very effective
sense.
For example, sharks can detect all vibrations in water, changes
in water temperature and salinity level, and minute changes in the
electrical field set up by moving organisms. In addition, their large
number of gel-filled cavities (Lorenzini ampules) are perfect electric-
ity detectors. Along with rough rays, they use these detect-
ors to hunt their prey and can perceive currents as small
as one 20 billionth of a volt, a truly glorious ability.
Imagine the batteries in an average
house. Sharks would be able to
detect the current emit-
