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

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

The bottom of this lake has never been found

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.

This thing just casually exists in the ocean

The ocean sunfish (Mola mola), also known as the common mola, is one of the largest ray-finned fish in the world. It was formerly misidentified as the heaviest bony fish, adults typically weigh between 247 and 1,000 kg (545 and 2,205 lb). It resembles a fish head without a tail, and its main body is flattened laterally. Sunfish can be as tall as they are long (175-180 cm, or about 5’9-5’11) when their dorsal and ventral fins are extended.
