The Blue Planet: A Natural History of the Oceans (2001)

Watched some of this docuseries.

Put this on the television. Started back on Episode 1, but it's just playing in the background. I want to get in the habit of having documentaries in the background as I work, because I normally get bogged down in watching a series in detail. But I realized that if I don't remember most details about a movie I watched intently, then maybe watching something passively is an equivalent experience can have as much value as watching something intently.

The series was expiring today and I intended to watch as many episodes as I could. I started with the third episode, but I was under the impression I had already seen the episode in its entirety. For better or worse, I was feeling extremely sleepy while watching the third episode and decided not to watch any more of the series. Hopefully Netflix eventually renews it.

Netflix determined the movie for me as a 71% match. I decided to give the movie a thumbs up|thumbs down|neither a thumbs up nor a thumbs down.

B: Huh. Interesting: swells can become large in the ocean when far from the shore (more precisely, from the sea floor).
B: I started wondering about the difference between "sharks" and "fish". [Apparently it's a comparison of "cartilaginous fish" (which includes sharks, rays and chimeras) and "bony fish," respectively.]
B: Upon seeing dolphins, I wondered how dolphins, being mammals, evolved; certainly not from fish. [In short, land mammals that began to become semi-aquatic and eventually fully aquatic.]
A: It's interesting to be reminded that various animals in the animal kingdom, particularly those in the oceans, are carnivores. Traditionally, I think of sharks as being the carnivores of the sea. Here we see dolphins catching fish, followed by birds and sharks taking advantage of the situation.

A: How did dolphins acquire the strategy of using bubbles?
B: Why did many of the squid die after mating? [The best answer I could find is that their life span is short, so I suppose they would die regardless of mating.]

A: "Evolutionary arms race."
A: Whoa. The male attaches permanently. Interesting.
A: I wonder about the timescale of evolution on the deep ocean. Is it faster, the same, or slower as life near the surface.
A: "150 million years they've remained unchanged." - the narrator speaking about a specific shark
A: The carcass of a whale from the first episode makes a reappearance. There is, however, different narration and footage.

The shearwaters follow the fish down to as far as they can go.

B: Flotsam.
A, B: "As weeks pass by, these group rubbing sessions will become more overtly sexual, but now it's just flirting in the sun." B: 39 minutes
A: Wow. 15 meters. B: At 46 minutes: "Perhaps as deep as fifteen meters."
