Deep sea

The deep sea is where the ocean becomes deeper. It is also the point of transition from continental shelves to slopes. Despite the extreme pressure, organisms called deep sea fish can survive there. For example, the anglerfish can produce its own light source called an esca.

Some animals can thrive by feeding on marine snow. In 1960, a bathyscaphe called Trieste went down to the bottom of the Mariana Trench, which is the deepest point on Earth. There aren't any plants at all in these depths, so all fish in the deep are carnivores.

 Organisms 

Some organisms can live in the deep sea, such as the gulper eel, lanternfish, anglerfish, and more. They have many adaptations that can help them survive in the harsh conditions.

 Characteristics 

 Sunlight 
Sunlight cannot reach the deep ocean, except parts of the mesopelagic zone.

 Pressure 
The pressure is many high, so many people can't survive.

 Exploration 

Exploration is very limited in the deep sea due to the extreme conditions.
