Maybe they came from a gas planet and they came to invade the deep sea because that's what home looks like. Unfortunately, these super intelligent beings failed to understand that, on Earth, most of the fun happens on land.
- Yetanfou 8y agoDoes it? For us, certainly, but put all land-life on a scales and all sea-life on the other side and it'd most certainly tip to the sea-side.
- stewbrew 8y agoYou're probably right if you look at the mere amount of bio mass. I'd wager you're wrong if you look at the complexity & general level of activity of life forms. Unless you find a way to efficiently get the oxygen out of the water and to deal with water pressure, I think most life forms are better off on land.
- Yetanfou 8y agoIt is easier to extract oxygen from water and there is plenty of it - notice the difference in size between a fish' gills and a mammal's lungs. Pressure is only a problem if you try to fight it, keep your body at the same pressure as the surrounding water and you're fine.
- caf 8y agoThis paper has some information: http://www.pnas.org/content/115/25/6506 http://www.pnas.org/content/115/25/6506 (see "The Distribution of Biomass Across Environments and Trophic Modes"). They divide biomass up into three environments, with 6 Gt C in "marine", 70 Gt C in "deep subsurface" and 470 Gt C in "terrestrial". You can also see in their analysis that the huge biomass bias towards the land is due to plants and fungi, which overwhelmingly favour the land; among animals there is actually more biomass in the oceans.
- imaginenore 8y agoThey count trees as biomass (which is correct, but it's not really the fun part). If you only count the animals, the marine and deep subsurface surely is way more abundant than the terrestrial life.
