Far more animals than previously thought likely have consciousness, top scientists say in a new declaration — including fish, lobsters and octopus.

Bees play by rolling wooden balls — apparently for fun. The cleaner wrasse fish appears to recognize its own visage in an underwater mirror. Octopuses seem to react to anesthetic drugs and will avoid settings where they likely experienced past pain.

All three of these discoveries came in the last five years — indications that the more scientists test animals, the more they find that many species may have inner lives and be sentient. A surprising range of creatures have shown evidence of conscious thought or experience, including insects, fish and some crustaceans.

That has prompted a group of top researchers on animal cognition to publish a new pronouncement that they hope will transform how scientists and society view — and care — for animals.

Nearly 40 researchers signed “The New York Declaration on Animal Consciousness,” which was first presented at a conference at New York University on Friday morning. It marks a pivotal moment, as a flood of research on animal cognition collides with debates over how various species ought to be treated.

    Seems like a strong argument that consciousness cannot be determined by testing behaviors.

      True, you can’t test a literal rock and expect the result to be telling of counsciousness. Good thing the researchers aren’t solely determining it by testing behaviour, and instead selected a group in which emergent intelligence is one of the probable phenomena.

        Is emergent intelligence the scientific definition of consciousness? The article seems to be describing something else.

          Is emergent intelligence the scientific definition of consciousness?

          There exists no practical or effective difference.
