Invasive bloody red shrimp confirmed to have spread to all 5 Great Lakes

According to experts the shrimp was brought over by big cargo ships

Scientists have confirmed a tiny invasive shrimp species from Eastern Europe lives in Lake Superior, previously the final Great Lake to have avoided the spread of the species.

The bloody red shrimp is about half an inch long, bright red, hides in rocks during the day, and glows if you shine a flashlight on one at night.

According to experts the shrimp was brought over by big cargo ships.

The shrimp comes out at night to feed, when young the shrimp eats plants, as the shrimp ages it moves on to eating small creatures.

Ceci Weibert, Michigan Aquatic invasive species program coordinator for the Michigan department of environment, Great Lakes and energy joined Local 4 Live to tell us more about the shrimp and invasive species in the Great Lakes.
