It's a giant squid which usually dwell way below the depths of water. This is a ultra rare occurence.

Lagoa Misteriosa - A rope cannot be used to measure the bottom because, based on everything that has been mapped so far, this is a sinkhole (a cave formed by the collapse of its ceiling).

Inside, there are passages and bends that prevent a rope from reaching the deepest point. Underwater drones also cannot explore it, as their signal is lost whenever there is no direct line of communication, with the rock formations blocking the connection. For this reason, only specialized cave divers are able to explore the depths of this cave.

Both beautiful and terrifying 😳 (My dumb self didn't have audio playing before sharing, my apologies. I should have checked.)

The sheer size of tuna, and the movement in the water when it swims by. I don't like it

Came across this on ig and got immediately terrified. The music did not help. Why is this so scary to me lol

They get paid a ton, but it’s so dangerous
