Thanks, Py, and a couple of ideas.

So. Different biomes and outposts on them, that could be quite romantic. But we need to come up with a reason why we should stay on such planets at all. After all, we can, in theory, just catch a couple of individuals and breed them elsewhere. We need to think about it. (I continue to reason with myself. I like it. I'm training my imagination)

Addition:

For example, a unique atmosphere for each organism. We can grow it on another planet, but then we will need a special building with a protective dome and additional costs for the synthesis of the atmosphere.

Also, a food chain that rests on the resource collected in a given biome, like the old "local flora". That is, if you breed an organism on another planet, you will need to supply this resource there. Although what prevents you from growing it too.. Then you also need a unique soil composition. Liquids. Perhaps microorganisms, bacteria, viruses. Lighting, by the way. Emissions from the parent star. Magnetic field. To make it easier to grow the organism in its native environment.

But in order to more or less start growing an organism in another place (for example, in a future biotechnological center), serious technologies of genetic modifications are needed. And here the idea of ​​how we used to get the first creatures will come in handy. That is, DNA samples, etc. That is, this will become a later technology.
