SpidersGettingBigger-GlobaW
l armingtoBlame?
A group of Danish scientists wondered whether global warming would make the hairy,
meat-eating wolf spiders of northeastern Greenland bigger, since longer summers mean
more hunting time.
The spiders can live for at least two years, and the researchers found that, in years
when spring came early, the animals grew larger, on average.
For example, when spring came 30 days earlier than usual, some spiders grew
exoskeletons that were 10 percent thicker than average, resulting in bigger bodies
overall.

Snakes
There are around 3000 snake species in
the world, and about 375 of these are

Snakes can be found in all types of
habitats.
While some climb trees, others live
underground, and still others are found in
the waters of lakes and even seas.
