Dolphins are exactly why I feel SETI is such a misguided (in a sweet way) effort. Here we are, searching for extraterrestrial intelligence while we can't even communicate with the other intelligent species on our own planet. Glad to see we're making progress though!

There's no reason we can't pursue multiple lines of research in parallel. It's probably more efficient too.

I will wager money that their names translate to things like:

   Big nose
   Funny tail
   Horny boy
   Big mamma
   Deep swimmer
Not just amusing, but also useful. By correlating individual behaviors and physical features with names, we might be able to unlock dolphin language! Which would be incredible!

Someone should define a canonical way to transform dolphins' whistles into syllables. Then we could at least sort of refer to them by their names.

Apparently, dolphin trainers have the ability to whistle their names:

"Her name was really Cathy. Well, not really. Her real name was [whistles]."[1]

SETI is not misguided. We've known for a long time that Earth was hospitable to intelligent life (us). That there are other species with similar levels of intelligent just makes Earth more awesome.

But it would be a complete mindfuck if we found other intelligent life in space, where before there were mainly only stars, rocks, and interesting formations of liquid and gas somewhere in between. It would change everything.

“Hey everybody! I’m an adult healthy male named George, and I mean you no harm!” That would be more like "Hey everyone, I'm George". Humans also 'encode' information in that sense - from that introduction you could probably tell age, general health and friendliness. The day we can talk to any stranger dolphin and have a real conversation will be alike to contacting alien life.

Actually, I don't think it will be all that alien. The conversation will probably be quite understandable. You will get conversations about fishing, who's pregnant, who you want to make pregnant, how your kids are doing, the temperature of the water, where the predators are. They probably tell stories, but they will be quite understandable to us. Fundamentally it's because the basic constraints of their lives are just like ours: get raised by mom, have friends, learn to hunt, mate, avoid predators and have fun while you can!

Parrots call each other by names as well[1] and crows have been shown to speak in two different dialects depending if they are with a group or among individuals[2]. In the same link about crows, they have also been seen using tools in the wild and in experiments using "meta tools", something that only primates have been observed doing (using one tool to reach another tool that will be used for their end goal [general…

A Murder Of Crows was done in concert w/ CBC, though they may have done their own post-production work (I've only watched the PBS version). Canadians should probably look to the CBC[1] to watch it. There's also an interesting blurb from the director here[2].

I think it's a mistake to say that they call each other by "name," because that implies the ability to form concepts/speak a language, and there is absolutely zero evidence for that. Even the article is careful to point that out:

While researchers often hesitate to apply the “l word” -- language -- to non-human communications, bottlenose dolphins and possibly other dolphin species clearly have a very complex and sophisticated communication system.

I bet there would be economic opportunity in developing commercial dolphin-human communication software and interfaces. Imagine how much benefit to deep sea construction and exploration there would be if training and employing dolphins using natural language was possible. Or to shipping, fishing etc.

I went through a Cetacean and cephalopods obsession last year.

What really freaks me out is what Dolphins looked like when they were still land animals:

Also the perceptual systems of octopus and squid are amazing. Cuttlefish can perceive the polarization of light. This helps for contrast and edge detection. Many Cephalopods (octopuses, squid, cuttlefish) can see with their arms and then replay the image on the other side like a video screen.

Dolphins can tell the difference between a quarter and a dime from 100m away using sonar. The click generating system emanates from the top of their head, in the area of the third chakra.

We have a very limited sense of space and an all too focused sense of self. But we have a lot of oil and we can dig shit up and drive around real fast and think we are really important.

Very true. On that topic, "...these communications consist of whistles, not words." Not to suggest that they're actually speaking a language, but a language consisting of whistles could still easily contain words. It would just have a different set of sounds.
