    What is your reasoning here? It's hard to follow.

    Yeah for me at least, I would rather an electronic than for someone to cut me around and put gills on me...

    YES an electronic would be better in every realistic situation I can think of.

    what i meant about active fighting between underwater creature, cause he said that under water, there are not much oxygene like in land, so, creatures, of underwater, don't have much energy as the land creatures, so, you cant see two underwater creatures, fighting, like a puma chasing a gazel or two other animals fighting,

    anyway, it's just a stupid thoght

    No, the reason is more likely that you don't spend a lot of time under water.

    The food chain is just as long in the water as it is on land, so there are lots of predatory species and lots of fighting and killing takes place. Think of sharks, but many fish are predatory, even the innocent-looking seahorse.

    All dolphins and all pinnipeds (seals and sea lions) are predators. The sperm whale, a toothed whale which is actually more closely related to the dolphins than to the baleen whales, is the world's largest hunter, dining primarily on squid. (All whales are carnivores but the baleen whales simply graze on krill, tiny shrimp that they catch by sucking in water and filtering them out, and that hardly qualifies as "hunting" in the vocabulary of a species that invented spears and guns.

    The point is that if an air-breather and a gill-breather of the same size get into a fight, the air breather will usually be the victor. I don't know if anyone has ever seen a battle between an orca and a great white shark of comparable size (there was a thread on this subject a couple of years ago), but the smart money is on the dolphin.
    "Creature from the Black Lagoon" was made in 1954, in 3-D. That's a typical woman's bathing suit from that era. (I remember, I was 11 then.) Women no longer had to cover their legs and they could show a little cleavage, but two-piece suits were not yet considered proper in the USA.

    The movie is considered a classic. The gill-man is an enduring figure in sci-fi, and monster movies often show his likeness in the background as homage. The story is said to be based on a legend of the Amazon River tribes.

    Marilyn Monroe made a sympathetic comment about the poor creature in "The Seven Year Itch," the character shows up in children's cartoons routinely, and two sequels have been made. The story has been re-worked as a musical comedy, a pinball game and a series of children's books.

    It has been immortalized by a paleontologist who named a species of fossil amphibian Eucritta melanolimnetes, literally, "creature from the black lagoon."

    What about liquid breathing? It'd be cool I bet.

    http://ssuba.com/ - looks fun

    I think having humans live underwater is probably not difficult, the problem is that it does not interest investors.

    I think maybe if you can have an underwater glass bowl the size of a restaurant sitting at 40 feet, would be a big attraction. Hmmm... Dubai....

    yes it's possible with a suba-like device (http://ssuba.com/) and a sunken submarine to dry off (also attached to the surface for air.) I imagine building a metal dome is cheaper than a submarine. The costs are lower than I originally thought for just 2 people. Maintenance and ongoing costs will run high, but there is no reason someone like David Blaine couldn't do it for a month.

    In summary of what I've read:

    It was extremely self-sufficient:

    Electricity - Bicycle and Solar Cells
    Air - Algae
    Water - Air2Water technology (Water Vapor -> Water)

    But food was occasionally brought from divers as he was in a stagnant flooded gravel pit.

    If he was in an ocean the box seems completely self-sufficient. I for one think this is unbelievable, I never heard of it before.

    Eventually, yes. But usually I run away or get sued before then.
