Otters are part of the Mustelid family which also includes ferrets, weasels, badgers, skunks, and minks. Otters existed for 30 million years.

These otters hunt in social and hunt in groups. They have a short rest in the middle of the day and the night in dens. In this case under our apartment building. In the wild, they shelter in dense vegetation, under tree roots, or among boulders. 

They mark their territory with scent glands located at the base of the tail 
They also communicate through vocalisations such as whistles, chirps, and wails.[2]
