In science class we dissected various animals including
starfish, earthworms, crayfish and frogs! Though it was very
gross, I learned a lot about the different systems in the body, and how
complex each one is. Today I am going to share with you some of the
information I learned about the earthworm!
Well first of all, earthworms are all boys and girls, so they
are "shims!" That's what I call them, anyway.
The longest "shim" was 22 feet long! But most earthworms are
under a foot (12 inches) long. Giant earthworms are around 10
feet and live in Australia and the northwestern area of the
Worms eat dirt. Dirt is good for them because it contains
decayed creatures (made up of protein) and minerals. You can tell
which side the earthworm's mouth is on because it looks like a snout. The
rear side of the worm is pointier and doesn't have a snout.
To reproduce, mucus is formed between two worms. Each worm
releases both sperm and eggs into the mucus, and then the
earthworms go on with their lives and start eating more dirt.
They never go back to see if their offspring survived or not.
Very romantic, eh?
An earthworm usually is eaten by a bird or another animal, so
their lives are pretty short. One of their predators is a
flatworm called Artioposthia triangulata. When it was transported to
Northern Ireland, it reduced earthworm numbers so that the island was
totally cleared of them!
Well, I hope you enjoyed my article and learned a lot about earthworms.
