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.
Welllllll… What if you found out that every time you cut into a plant, it let out a high pitched scream that humans can’t hear?

Yeah the fresh cut grass smell is actually a call to aid. They “think” the damage is caused by herbivorous insects, so they release chemicals to attract carnivorous insects to come and kill the other insects.
Plants probably qualify for a separate category of low sentience. If you’ve grown plants you know they’ll turn towards the sun, and you need to move them around a bit to make sure they don’t end up with a prominent lean. Some plants will use their tendrils to wrap around a trellis for extra support.
I don’t think we can qualify these actions on the same level of sentience as animals, but there is certainly something there. All living things probably have some degree of this, since they react to stimulus with chemical signaling. That’s not terribly different from what we do.
