The Aliens that never left

See this is why the ocean scares me...

I’ve been saying this since forever! I made my husband sit there and watch it with me lol

When I was a young child, I thought sea stars were pretty but I was desperately and irrationally afraid of stepping on a live one when I was swimming in the ocean. Good job childhood me.

Maybe we're the aliens

My guess for aliens on earth in the sea would have been octopuses.
