Today my daughter and I met an octopus (Octopus Californicus) at the aquarium in Long Beach, CA. She was very friendly and used her suction cups to grab onto us. The suction cups are very strong and can leave an impression of rows of circles on your arm. This octopus is an artist! Her trainer puts (non toxic) paint onto paper and the octopus grabs on with her suction cups. See below for her art work.
