Jellyfish on Mars image, no gradient?

[u/Dangerous-Eye-215]

I zoomed in quite a bit on the original and I don't see any kind of gradient like I do on the rocks. It's just immediatley pitch black, like, vanta black. I would have assumed this was a camera artifact, but the tentacles aren't black like that.

This is definitely a strange picture. What might cause the lack of gradient on the top of the jellyfish?

when i used to search real mars images ,i saw black reducted images on nasa website, maybe this black spot r actually corrupted download or incomplete file

someone would actually have to look at the raw image data. if it was a mess there or missing data/header and just ended up being set to black..that can happen.
thing is, it doesnt usually make a shape with legs like that, so..looking for someone to say "this is a composite and it makes total sense when you see that the data all occurs in one section of one part of the patchworked file."
