Yes they do and ask Bob Ballard if you want some tips.
bioluminescent animals live in the deep layer of the ocean. including jellyfish,octopses, and squid.
Mixed Layer Main Thermocline Deep Water Layer
Its a process called chemosynthesis I think.
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.
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.
Deep water layer
some animals digg down all the way the deep of the ocean and there are lots of warmth there
because there are many animals
The really deep, bottom layer of the ocean.
false
Jelly fish and also octopus.
The second cooler layer of ocean water is called the thermocline. It is the region of rapidly decreasing temperature with depth, typically found between the warmer surface layer (epipelagic zone) and the colder deep layer (abyssal zone) in the ocean.
