*Lemmus lemmus* is the scientific name for the European lemming, a small rodent found in northern Europe. It's known for its fluctuating populations and occasional mass migrations. Think of it as the 'Taylor Swift' of the lemming world – always making headlines and sometimes disappearing for a while. 🎤 It's a solitary animal with distinctive markings. These population booms and busts greatly impact the Arctic ecosystem. This species is vital to the food web in its native environment.
