Are Octopuses Friendly?
Octopuses are not friendly to humans in the ocean but can become accustomed to people in captivity. Some octopuses in an oceanarium can become quite friendly and amiable to humans.
According to The Natural History Museum, London, “Octopuses appear to be able to recognise individuals outside of their own species, including human faces.” And the Scientific American reports, “one cuttlefish [which belongs to the class Cephalopoda that includes ocotpuses] reliably squirted streams of water at all new visitors to the lab but not at people who were often around.”
