Deep-sea creatures live under water in an ocean or sea. They live in deapts such as trinches or caves. They are atleast 40 to 50 miles under water.'

There no "caves" in the deep oceans. You find them in shallow coastal seas and coral reefs. The oceans are NOT "40 to 50 miles" deep - those figures are rubbish. The mean depth of the abyssal plains is about 3-4 miles at most; some subduction trenches like the Marianas are deeper, but none reach even 10 miles.
Scientists refer to the organisms that live below the bottom of the ocean as extremophiles, which are organisms that thrive in extreme environments. These organisms have adapted to survive in conditions such as high pressure, darkness, and extreme temperatures that are present in the deep sea.
Organisms that live in the bottom of the ocean include deep-sea tube worms, anglerfish, sea cucumbers, deep-sea octopuses, and various types of bacteria and microorganisms. These organisms have adapted to survive in extreme conditions such as intense pressure, cold temperatures, and lack of sunlight.
lol your scerwed i have the same question in my pearson succes thing
Organisms that live in extreme environments like deep-sea creatures or cave-dwelling organisms may not have evolved to see light due to the absence of it in their habitats. Additionally, some microorganisms such as certain types of bacteria do not have the necessary structures or pigments to detect or utilize light for vision.
Monera is a traditional biological kingdom that includes single-celled organisms like bacteria. These organisms can be found in a wide variety of habitats on Earth, including soil, water, and even within other living organisms. They are found all over the world, from deep sea vents to hot springs.
Deep sea producers are the organisms that live so far down in the ocean, that they have to make their own food in order to live.

Fish survive in the ocean by their gills. Fish need oxygen too, just like many other living things. They do not breath the water. Their gills receive oxygen and they breath that way. that's why fish CAN live under water. Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fish include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, and viperfish.Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor.Deep-sea organisms generally inhabit bathypelagic (1000m-4000m deep) and abyssopelagic (4000m-6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200m-1000m deep) zone as well.

They live deep deep down at the bottom of the Sea
Deep-sea organisms have been difficult to study because the ocean floor is hard to get to.
Organisms that live in deep-sea hydrothermal vents are an exception as they derive energy from chemical reactions in the absence of sunlight. These organisms, like certain types of bacteria and archaea, use a process called chemosynthesis to convert minerals and chemicals in the vent water into energy for survival.
they usually die
These organisms do not need oxygen. They are called anaerobes.
Organisms that do not require sunlight to live are called chemotrophs. These organisms obtain energy by breaking down inorganic compounds rather than through photosynthesis. Examples include deep-sea vent bacteria and certain types of fungi.
