Night Footage: River Otter Latrine at the Smithsonian Environmental Research Center

For North American river otters, pooping is a social event that lets them exchange information, know who's in the area, and who might be interested in mating. These pooping areas are known as "latrines." In this night footage from a camera trap, a group of river otters at the Smithsonian Environmental Research Center add their own essence to the river otter latrine on the docks.
