Why is captivity harmful for all cetaceans, rather than just orcas? Specifically I'm curious about bottle nosed dolphins. My opinion used to be that it's unethical for orcas because 1) of how they're treated (obviously), 2) the captive average lifespan is shorter than the wild average lifespan, and 3) they're at the top of the preditorial food chain. Dolphins seem to be happier around people bc of how social they are and they're captive lifespan tends to be longer. What is your opinion?
