Earthworms are creepy crawlers that give many people the chills upon
sight of them. Burrowing deep in the earth and feeding off the remains
of the dead, these creatures are amazingly simple. Many people would be
surprised to hear that there are earthworms that are nearly 10 feet in
length! Many countries around the world are home to these beastly worms.
It is amazing how large they grow because there is so little to them.
They have a digestive system that runs from their mouth to anus and two
ganglia that enable their senses. They breathe through their skin and
are all hermaphroditic.
One
species of giant earthworm, called the Giant Gippsland Earthworm is
found in Victoria, Australia. With an average length of at least 1 meter
to grow up to 3, these worms are longer than many snakes! They live in
deep burrow systems and are a species that is currently under a
threatened status, so they are rarely seen by most humans.
The
Giant Gippsland Earthworm has had such a decrease in numbers as a result
of farming. Some scientists contribute it to the act of tilling the
land. Another contributor is that these earthworms have a slow
reproductive rate, as well as maturation rate. It takes nearly five
years for the worms to reach maturity, and they can live up to ten
years. This is an astounding life span compared to many other
invertebrates.
