Different Planetary Conditions

I’m curious on how different species can adapt in different conditions. If a planet with a low atmosphere is present, then most creatures there would have large ears correct? If the planet has low gravity, then creatures would be more close to the ground. But what about other biospheres? Magma covered mountains, sulphur filled oceans, and tidally locked planets.

Here’s a couple of examples of the sort of thing we are thinking about (it may change in the future).

The microbes can adapt to different light levels by using pigments (if there is too much light) and bio luminescence (if there is too little).

Similarly with sulfur content in the oceans. If you live by a hydrothermal vent that is spewing hydrogen sulfide then you can get a chemoplast to make it into sugars rather than using a chloroplast.
