The giant earthworm is exactly what it's called, a giant earthworm. They are native to Austrailia in the rainforests or along riverbanks or streams. They can be red, brown or even blue! They can go up to 2 feet long, which is long enough for two adult males to hold it end to end. This a pretty weird bit of information, but Austrailia actually made them a protected species. They even made a museum about these guys! I bet you don't know what makes them endangered. Their cows eat them. Yep. Don't drink Australian milk.
