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!
High temperatures destroy coral reef
High temperatures destroy coral reef The highest sea temperatures ever recorded -
31.5?C - have destroyed coral in Belize. This is the first time
this has happened in 3,000 years. Scientists blame global warming
and the El Nino weather pattern for the destruction of the coral.
The high temperatures caused the single-cell algae, which give the
reef its colour, to leave. This caused the coral to collapse and is
endangering the fragile marine environment. 4 MAY 2000
