A young fish swims past an old crab. The crab sees the faint outlines of a school of jellyfish.

Crab: “Best find shelter, youngin’. There’s a storm floatin’ in.”

I hate this place.

i heard a similar idea that if humans can’t see air then maybe undersea creatures can’t see water. so fish would be like birds and crustaceans would be like land dwellers. so yeah jellyfish being storm clouds checks out
