How Deep Have We Been in the Mariana Trench?

There's no way of proof to me that somewhere in the Mariana trench, okay, these are probably mermaids. A lot of people think that they're going to be human size, but it's a human fucking of fish, right? Yeah. So why wouldn't they be like human top fish bottom, but on fish scale? This one sent it by level nine house and Yachru drew to Evanport. It's by Yachru answers user Amad who asks, don't you wish that donkeys? It only existed in legends. Instead of wishing mythical creatures to be real, why not exile trouble making creatures into legends? I follow this question up to this point
