There are approximately 2,700 different kinds of earthworms.

In just one acre there can be over a million earthworms eating 10 tons of leaves and other plant material and turning over 40 tons of soil.

Many of the earthworms we can find in North America are descendants from those which came from Europe. Early settlers brought plants with them and worms came with the soil.

Baby worms are not born, but hatch from cocoons smaller than a grain of rice.

The Australian Gippsland Earthworm grows to 12 feet long and can weigh 1-1/2 pounds.

The largest earthworm ever found was in South Africa and measured 22 feet from its nose to the tip of its tail.

A beef tapeworm can be 30 feet long and have up to 2000 segments to its body.

In 20 minutes a leech can absorb five times its weight in blood.

Virtually every living thing existing in the wild is likely to have one or more parasites living inside of it.
