The fish that have been raining down in Alaska are called "Arctic lampreys," and they have a mouthful of scary-looking teeth.

The parasitic fish lives by attaching itself to another fish (most often salmon) and feeding off its body.

Most of the lampreys were found dead, but one was found alive outside a Fairbanks thrift store, according to CNN.

"Two gentleman came in and asked if we have a bucket with water because there's an eel in your parking lot," said the store's owner, Sue Valdrow. 

Another resident noticed one on his lawn.

The Alaska Department of Fish and Game speculates that the disgusting eel rain may be thanks to gulls fishing the lampreys out of the ocean and then dropping their carcasses onto lawns. 

"If you look closely at them they have holes on both sides that may have been made by a gull or some other kind of bird," said Mike Taras of the Alaska Department of Fish and Game.

Lampreys live primarily in the mud of rivers and tributaries throughout the state, so it is a rare event that residents are seeing them.

Young Arctic lampreys are blind and feed by filtering micro-organisms through the water.

"I wasn't sure what to do when lampreys fall from the sky," Sue Valdrow told CNN. "I've lived in Alaska for 12 years and I've never seen anything like this."

Put it on the stove and cook it? Apparently, lampreys are a delicacy in Alaska, according to the Huffington Post.
