What are the alien creatures in the sewers of North Carolina?

Covac, a professor of biology at North Carolina State University, said that this tumor may be a community of thousands of organisms in bryozoa class, also known as bryozoa, belonging to invertebrates. It uses a structure called tentacle crown to catch water debris for a living, which can move about one to ten centimeters every day. He said these are harmless creatures.

However, Wood, secretary-general of the International Association of External Anal Zoology and professor of life science at Wright State University, holds a different view: "This is not an external anal animal, but an annelid belonging to a crown-wheel animal. Wood even asserted that it should belong to Nemuropoda family of Zoelliformes, a creature suspected of Tremella.

He said that trematodes are often used as fish feed, and this creature usually appears in soil or sediments, especially near polluted water sources. Because the bugs in the film live in water pipes without soil, they have to be coiled together to form a meat ball.

As for the contraction like a beating heart, Wood said it was because an earthworm in the community contracted first. "Stimulating other bugs to contract together will have a chain effect and make it look like a mass of meat beating. 」

Buquan, the environmental coordinator of the public sector in Raleigh, agreed with Wood. He said that biologists in the department also confirmed that it was an earthworm. Buquan believes that there may be some small tree roots in the sewer, which gives the insects a place to entangle. In fact, the width of the sewer is only six inches (about fifteen centimeters), while the size of the earthworm community is only about half an inch. He said that the camera light is very hot, and the shrinkage of earthworms may be caused by the camera light.
