What a way to begin 2014. First we learn about dogs who poop and pee aligned with the Earth's magnetic field and now spy cameras used to film a new BBC documentary called Dolphins: Spy in the Pod show that dolphins get high on pufferfish. To wit, "When threatened, pufferfish can excrete a powerful neurotoxin: tetrodotoxin. The substance, which can be lethal in high doses but in smaller quantities is relatively benign, effectively blocks neurons in the brain from firing and therefore produces a narcotic effect. It is currently being investigated as a possible way to treat pain in cancer patients. The teenage dolphins appeared to be 'chewing puff' ... for no other reason than experiencing an altered state of consciousness."
We know that dolphins are very smart and emotional beings and many people, including researchers, view dolphins as persons and have vehemently argued that dolphins deserve much more protection than they now have. In 2013 India designated dolphins as "non-human persons" and banned their use for public entertainment anywhere in the country.
