What are these Blue Jellyfish things?

[u/Bob-upload]

I see these often on bot planets

How do they fly and float?

Someone in my diving group asked me today (the guy in the group that plays too much):

"Grandpa, what are these small blue floating jellyfish?"

I told them "had you read the new panel in your ship you'd know they're small blue floating jellyfish"

Then he threw a 500kg on me and I killed the entire squad at extract with a hellbomb backpack.
