Lost river creature adaptation

Deepca

With the Lost River in progress and creatures spawning in the Bonesfield and the Ghost Tree Chamber there is a slight problem with the creatures spawnpoints. Some, especially the spinefish and the blood crawler, spawn in the brine pools. As you know they are acidic, wich means they instantly die, resulting in many corpses down there. My idea is to make them imune to the acid. That would work best with the blood crawler, because in my mind their their long slender legs adapted in order to walk across shallow brine pools to protect their main body.

That sounds pretty cool. Especially with the long-legged crawler. Life should get weirder and weirder as we get deeper.

If creatures live inside that biome, they logically should be adapted to surviving in it.
