The Strangely Social Life of the Larger Pacific Striped Octopus

7:46 minutes

Most octopus species live their lives largely on their own. New research published in the journal PLOS ONE, however, documents unique social behaviors among several specimens of the larger Pacific striped octopus, including strange mating approaches, the cohabitation in dens by mating pairs, and sharing of food. Richard Ross, a senior biologist at the California Academy of Sciences, describes some of the species’ unusual habits, including a method of hunting shrimp by tapping the prey on the back to surprise it (see video below).
