Yeah, that's getting there. That upper picture is pretty good for density. I'm really talking larger scale than this though. In suitable habitat there might be more covered terrain than not. But some limits probably also spring from demand on the system to present all these wavy little blades. Still we've all only scratched the surface of whats to be seen so perhaps I'm asking for something that's already hiding out there somewhere. Of course, since we can't differentiate anything about life on the planets from space it may stay hidden forever.Tussock does come in larger areas sometimes. And also cohabitating with other fauna.
Also there's a valid point that these are desert-like environments where it may only support that life in very small areas too. Something that could be expanded as the atmosphere's we can get out in expand.
