| What Shells Are In Lake Michigan |
The Usual Suspects: Zebra and Quagga Mussel Mania
Forget about those pearly white finds from tropical beaches. Lake Michigan's shell scene is dominated by two unwelcome guests: the zebra mussel and its equally prolific cousin, the quagga mussel. These guys are like the cockroaches of the underwater world – they're tough, adaptable, and there are a LOT of them. Their tiny, striped shells (zebra mussels) or triangular, brownish shells (quagga mussels) often carpet the lakebed, and you might find them washed up on shore too.
Fun Fact: Zebra and quagga mussels are actually invasive species! They hitchhiked on ships from Eurasia and are now major players in the lake's ecosystem. While they might not be the prettiest, they do filter the water, which can be a good thing. But be warned their filtering skills are a bit too enthusiastic, sometimes disrupting the natural food chain for native fish.
Where Have All the Pretty Shells Gone?
Those hoping for a treasure trove of colorful seashells are likely to be disappointed. Pollution, habitat changes, and (you guessed it) those invasive mussels have pushed most native mussel and snail populations to the brink. However, with a keen eye, you might just uncover a few hidden gems. Keep an eye out for pea clams, with their tiny, pea-sized shells, or even the occasional empty shell of a native mussel species.

Pro Tip: Head to areas with less zebra mussel dominance for a better chance of finding native shells. Sandy beaches or rocky shores might offer more variety than mucky bottoms.
So, You Want to Be a Lake Michigan Shell Sherlock?
Here are some tips for your next Great Lakes shelling adventure:
- Timing is Key: Head out after a storm or heavy waves. These can churn up the lakebed and unearth hidden shells.
- Look Beyond the Beach: While you might find shells washed ashore, for a better variety, consider exploring areas with exposed rocks or shallow water with permission, of course.
- Brush Up on Your Mollusk Knowledge: There's a surprising diversity of freshwater mussels out there! Do some research beforehand to know what you might find.
- Leave No Trace: Respect the delicate ecosystem. Take only pictures, leave only footprints, and admire those shells in their natural habitat!
