DraconisTheWyvern
First off, sorry if I was getting snippy on my last two posts, it was getting late and I wasn't at 100%, which is my fault.
DraconisTheWyvern none of which saved the dogs in the video, or the deep sea fish when they are forced into shallow water, none of which will save the deep sea diving whales either in space
Because none of them had those features needed to survive in the other environment; they're adapted to their environment and require it to survive. These creatures would be adapted to the conditions of space by nature, just as deep-sea fish are adapted to high-pressure environments, certain bacteria are adapted to the absurdly hostile environment of certain hot springs in to 400+ degree range, etc.
DraconisTheWyvern high pressure wants to go to low pressure. any hole created in the creature would be a death sentence because the blood and gases want to go to the low pressure area.
That's assuming the creature is a singular organism with a singular network of organic tissues. And that the creatures would have lungs, which is kinda silly in a vacuum anyways. Honestly, very few of these creature's organs would do more than superficially resemble terrestrial counterparts, simply due to the egregious differences in environment.
DraconisTheWyvern none of which will save you from the rupturing of your lungs and suction when your body is exposed to space. the video you linked to even showed that.
For a human. These creatures would have very little in common with humanity, to be honest.
DraconisTheWyvern thats not exactly how zerg work; they dont create new zerg from bio-mass they do actually give birth. the zerg hatcheries and larva are literally zerg eggs. they breed asexually unless the guy who says "okay lets try this" says other wise (play heart of the swarm/evolution missions)
an no holes? hardly
They actually do; if you read the game intro book for the first game (which has precedence for canon) it explicitly states that the Zerg developed 'ultra-dense carapaces' after assimilating the species that became the Overlords and the species that became the Leviathans.
DraconisTheWyvern warhammer 40k is not very good with science you realize that right?
It's science fantasy in all honesty, but so is this conversation. We're talking about 100ton+ sized space-dwelling organisms that can successfully fight off high-tech ships run by reactor-made AAs.
DraconisTheWyvern okay so lets assume they dont travel to any other nebula; well than they are quite literally swimming in it but problem is every other space creature will be using that nebula as well.
Yup, limited resources is the reason the predatory ones also exist.
DraconisTheWyvern a nebula is NOT a source of light; all the bright colors you see etc.? that is from the gases reflecting light. a nebula is a collection of gases and dust. it is bright for the very same reason a bright red paper is bright red.
it does not matter how bright the nebula is; what matters is the light's wave length and what wave length the creature can take. for example plants dont just take in all the lovely photons they actually discriminate what photons of what wave length they take in. in other words they need a source of light. an yes some nebulas have stars inside them. their movement though will be restricted because if they move too far away from a source of light if they are photo-synthetic they will lose energy and be un-able to live.
And either way, photo-synthesis was an idea you brought up.
DraconisTheWyvern every creature/animal survives in spite of their environment. believe it or not the environment we humans are in does try to actively kill us. this is why we have evolved resistance against oxidation of our DNA and cells, this is why we evolved to be resistant against metal poisoning because iron will kill you in a sufficient amount and do utterly nasty things to your body. an we also use these materials as well.
every animal survives in spite of their environment.
That is also true, but we are reliant on our specific conditions and, as you mentioned, are adapted specifically to survive in it. It's why we don't survive very well when buried or submerged for extended periods of time, and yet we excel at finding and obtaining resources while on land in the right habitat. The idea is that these creatures are adapted to the nebulae, and as such would be engineered by evolution to have methods of surviving things like micrometeorite impacts, other instances of these organisms with predatory habits, etc.
And going back to an idea I touch upon earlier, who's to say these aren't massive colony organisms, similar to a Man-o-War or coral reef? Each type of organism has specific 'jobs' inside the colony, and each type reproduces its own type, but they all work together to survive.
Also, Tardigrades are a good example of a terrestrial organism that can survive space just fine. They hibernate and stop giving any f***s about anything trying to kill them, it's really fascinating.
