MN is home to a few native crayfish, plus an invasive one. They all look like baby lobsters that reach 2-5 inches long.
Found: In streams and rivers with rocky bottoms and logs to hide under.
Fun Fact: While humans have 46 chromosomes, crayfish have 200. This allows them to self-amputate limbs if caught and then re-grow them.

This water beetle is usually found swimming on the surface of a lake or pond where they swim wildly in circles. This movement makes small waves, which may help them find insects to eat via echolocation.

Many animals, such as squirrels, raccoons, owls, bats, weasels, porcupines, songbirds, and others, make their homes inside tree holes. The holes can occur from tree decay or broken branches, or else with the help of woodpeckers. While it's rare to see the occupant, let's assume it's a home for someone.

Squirrels love to eat pinecone seeds. You may come across a pinecone cob and scales in a pile called middens that the squirrel left behind. Some middens get a few feet deep under a squirrel's favorite lunch spot.

Lodges (Beaver homes): Look in shallow water for mounds of sticks. Beavers made these by chewing, carrying, and placing each stick in place with mud. The entrance is underwater.
Chew Marks: Beavers gnaw on trees to fell them and use them in building dams. The marks are unique to beavers and one of the best signs of beaver presence.
