Did Inks Lake get invaded by jellyfish?? 🪼
Nope!
🪼Ranger Jaeger found this clump floating near the water’s edge today and they are frequent visitors here at Inks Lake.
These clumps are called Bryozoans, a moss-like invertebrate that forms colonies, and can be found in lakes, rivers, streams, and other waterways.Different species take different forms, and can get up to 12 inches in length, but the majority of them form smaller clumps too small for the human eye to see.These invertebrates float around in the water or stick to rocks, logs, boats, or anything else solid in the water.They must have some really crazy HOA rules: no solo living, keep the vibrations to a minimum, must conform to the same aesthetic, so no wild shapes or flashy colors, and mandatory daily meetings. 
They are filter feeders, filtering water and digesting different particles and bacteria in the water, leaving our waters much cleaner than when they arrived and are a sign of clean, healthy waterways.If you see one of these in the lake don’t pick it up, just let it exist peacefully in its Lakefront property. They’re the Park Hosts of the water, in exchange for keeping us clean, they get to hang out with us. 
(Ranger Jaeger was *very* careful 
)If you spot a bryozoan on your boat, on one of our boats, or near our docks, don’t remove them unless necessary.If you do remove one, carefully scrape it off so you don’t end up harming the invertebrates.Practicing Leave No Trace in the lake means that more beneficial creatures like the Bryozoans can thrive.
