The river otters at Duluth's Lake Superior Zoo can swim up to 6 mph and remain under water for up to two minutes. But they have other skills.
A few times a week, Zhoosh and Anang spend their lunch hour out of the public’s eye, smearing card stock with paint, the Duluth News Tribune reports. It's part of the animals' "tactile enrichment" – the artistic expression is good for their brains, zoo officials say.
The zoo sells their creations for $35.
The otters were briefly displaced by summer flooding that closed the zoo for several weeks, but the otters returned in July.
