The layer of the ocean extending from the base of the thermocline to the bottom is called the deep zone or deep ocean zone. This region is characterized by consistently cold temperatures and limited sunlight penetration, which affects the marine life and ecosystems found there.
The middle layer of the ocean is called the thermocline.
Thermocline
Mixed Layer Main Thermocline Deep Water Layer
Thermocline
the first layer is the surface layer it is nice and warm and mixed with the waves. the next layer is the thermocline it is just warm not any thing special. the next is freezing cold i would not want to go there.
a layer of water in the ocean where the temperature declines rapidly with depth
The term you are referring to is "thermocline." It is the layer of water in the ocean where there is a rapid change in temperature with depth, serving as a barrier between warmer surface water and colder deep water.
Animals commonly found in the thermocline layer of the ocean include tuna, swordfish, and some species of sharks. These animals are adapted to the varying temperatures and oxygen levels found in this layer, making it a suitable habitat for them.

thermocline
The main thermocline is typically located in the ocean's epipelagic zone, which is the uppermost layer of the water column. This zone is characterized by a rapid decrease in temperature with increasing depth, creating a distinct layer known as the thermocline where there is a sharp temperature gradient.
