I'm sorry, even tuna have figured out how to escape tuna nets. Humans have to design special nets to prevent the killing of dolphins.
Don't get me wrong. I haven't sat down and watched The Cove with a bucket of popcorn and a bottle of ketchup.
I think what happened to the Dodo was a terrible thing, and that bird is considered to be quiet stupid, so it's not an intelligence factor that makes me care one way or another about the extinction of a species.
What I do object to is the wholesale belief that dolphins are intelligent and BECAUSE of this need to be protected. If that's the only criteria then a lot of animals need to go extinct (many humans as well).
My issue lies with said humans. Dolphins are not intelligent. No matter what argument you make, the science just isn't there.
I know I'll hear claim about their advanced language that's so advanced that we haven't been able to figure it out. Much like most adults can't figure out what a toddler who is just learning how to speak says. That toddler must be speaking a very advanced dialect that we adults just can't wrap our heads around.
No doubt I will also hear about how dolphins help people drowning at sea. Those individuals will no doubt have neglected the fact that only survivors are able to tell what happened. How many people were pushed further out to sea or drowned by dolphins? We may never know because those people are "lost at sea". Maybe the dolphins that did help merely got turned around. This would be a sign of intelligence, however. Murder takes planning.
Then there is the rapist dolphin. If this is a sign of intelligence, then dolphins need to be incarcerated for sexual assault.
Wow. This article has really digressed from it's original point.
My point is: Dolphins are dimwits.
