Picture the avocado green living room at your grandparent's house. Rust orange couch, potential for wagon wheel fabric, even higher potential that it's covered in sticky plastic.
Now, think about that sea of shag carpet at the bottom of the actual ocean. But instead of nylon pile, it's made of worms.
It's not just the stuff of nightmare, it's real: A city of tubeworms was discovered living in near freezing temperatures off the coast of Alaska. Scientists say some could be a few centuries old.
NOAA Ocean Exploration found the tubeworms using a remotely controlled camera to survey the seafloor about 650 miles southwest of Anchorage.
What are tubeworms? Scientists say they pose no threat to humans. "They can reach 10 feet in length, have no mouth, gut or anus, and studies show they can live more than 200 years, the Sacramento Bee reported, adding:
"Thousands of the worms stretched the length of two football fields and were thick enough to cover the seafloor like shag carpet in spots."
