Spiders that hunt at night often have a special layer at the back of their big eyes. It acts like a mirror to bounce light back into the eyes. On a dark night, this reflected light makes the spider's eyes seem to glow!
Thrown a lifeline
Thrown a lifeline It is hoped that a plan by the UN Food and
Agriculture Organization to change longline fishing practices will
help to protect sea birds. Many seabirds become hooked on the
longline hooks when they try to eat the bait before it sinks.
Fishing vessels will now need to protect seabirds from the lines
using different techniques. One method favoured by conservationists
is passing the line through a steel tube which shields the bait
from birds. Another method is to use a “scarecrow‿ hung
over the stern of the boat to frighten birds away. 24 OCTOBER 1998, P. 13
