Did you know that the more spots a male peacock has on his tail, the more likely he is to father babies, survive harsh winters and escape predators? Scientists think that only the healthiest males have lots of spots and that is why they are more successful than other males.
Whale of an appetite
Whale of an appetite Scientists say that a group of Alaskan killer
whales has recently started eating the region's sea otters,
possibly contributing to an overall change in the coastal ecology
of the region. Some colonies of sea otters in the area have been
almost wiped out, and the total sea otter population of the area
has recently declined sharply. As a result, the population of sea
urchins, which the otters usually keep controlled, has exploded and
is negatively affecting kelp beds. The kelp beds are the base of
the coastal food web. 24 OCTOBER 1998, P. 25
