From WTTW Chicago:

Scientists believe the Quagga mussel first stowed away in the ballast water on transoceanic ships from the Caspian Sea. The mussels made their way into the lakes when that ballast water was purged.

The tiny fingernail-sized mussels closely related to another invasive, known as the Zebra mussel, first appeared in lake waters here in 1988.
The Quagga mussel is now the most pervasive and destructive invasive species ever to enter the Great Lakes. Over the last 15 years, the Quagga population has exploded, eclipsing the Zebra mussel and infecting all five of the Great Lakes. Read more.

When participating in a crayfish participatory science activity, be sure to snap plenty of photos of any crayfish you catch or observe. Not only is it a great way to capture the fun and excitement of the day, but it also helps document the species present. To ensure accurate identification by scientists, it’s important to provide clear photos from multiple angles. Dorsal (top), lateral (side), and ventral (underside) views of the crayfish should always be photographed.To learn more about the specific features to highlight in your photos visit the link in bio or InvasiveCrayfish.org/Management/#Community
Who says “Back to School” means back indoors? While the weather is still warm, take your students on an outdoor science adventure by exploring crayfish in your local waterways.The Invasive Crayfish Collaborative invites grades 2-12 educators to take part in a hands-on participatory science activity. By catching, identifying, and reporting crayfish species in your area, students contribute valuable data that helps scientists better understand where native and invasive crayfish live.Check out what other educators have found and get involved: inaturalist.org/projects/great-lakes-crayfish
