eight eyes to track insects and other spiders. Then they leap as much as
50 times their own body length to catch their prey.
The centipede is an invertebrate, or an animal without a spine.
Ninety-seven percent of all animals on Earth are invertebrates.
Centipedes have long, segmented bodies, with each segment having a pair
of legs. Certain kinds of centipedes can have up to 177 pairs of legs.

bite their victims (usually sleeping cows and horses) and drink their
blood for about 30 minutes. This silent attack usually causes no major
harm to the unknowing victim.

black widow spider (seen in the background). Female black widows are
considered more dangerous than males and have even been known to bite
their mates!
With bands of red, yellow, and black, a Clark's coral snake lies curled
on a bed of leaves in a rain forest in Costa Rica. These snakes are shy
and not usually aggressive, but their venom can be fatal.
