After news recently spread that a neighborhood organization in Corte Madera, Calif., put up otter crossing signs, we set out in search of other unexpected brake-for-these-critters signage — like skiing kangaroos, angry deer and even wayward mermaids.

Anteater Crossing

You don't see this one every day, but it makes a great punch line in Colon, Panama. "Why did the anteater cross the road?"
