BBC releases Blue Planet II Trailer

Yeah we know more about space than we do our oceans.

We do know about our oceans. The reality is tough and survival techniques are the key in there. The big one always eat the small one. The big bad wolf (the human in this case) doesn't care about pollution (oil spill, plastic, marine debris, human trash, etc)
 
Loved the scenes with the dolphins and pilot whales coming together for a social meeting in episode 1.

And also the role of undersea vents as a possible origin for life, not just on Earth, but elsewhere in the solar system - not least Europa and Enceladus.
 
It's an amazing series so far. In episode 2 I loved the methane bubbles bursting out of the ocean floor, trailing silt like rocket exhaust. And the weird brine lakes at the bottom of the ocean and the toxic-shock contortions of the eel unwise enough to dive into it.

What I didn't love was the huge areas laid waste by deep trawler nets.
 
Yes the brine lakes were really like something out of SFF, weren't they? And the eels going into toxic shock - that was somehow a really disturbing piece of footage, though I can't put my finger on why. I've watched countless documentaries where animals have suffered, in hunts etc, but this was different, perhaps as it was so alien, so "weird".

Wonderful, wonderful series. I probably sound like a Daily Mailer now but the BBC Natural History unit really is worth the licence fee alone. Such dedication and vision.

I was like, did the Dolphins just make a deal with them??? Underwater international relations!!!! And I say that because they aren't the same freaking species. That's the only time I've ever seen an animal turn around and face their enemy with literally no aggression whatsoever. Did the Dolphin's fins move up and down? "Woah. Woah. Don't fight us, we can work together." Usually if an animal faces their enemy or a threat they either run or charge directly at them and fight til the death/one gives up. The dolphins actually thought what to do in this situation and implemented a plan!

Dolphins, sing, surf, have fun, make friends and make deals.
 
It's rare for false killer whales to attack dolphins, so the dolphins probably wouldn't have seen them as a threat. Also, as Attenborough said, it seems these groups knew each other from way back, so while it is a mystery, it's not as if the dolphins used brainpower to turned a dangerous situation around.
