Where is the profundal zone?
The profundal zone is located below the thermocline where the sunlight does not penetrate. Again, the size of this zone depends on the age and water clarity of the pond or lake. The profundal zone typically has lower fish populations because of the lack of oxygen during many parts of the year.
What is found in the profundal zone?
Common inhabitants of the profundal zone are leeches and other annelid worms, some species of insect larvae, and a few types of crabs and mollusks. In marine profundal zones echinoderms such as sea urchins, and crustaceans such a a few species of crabs, are also found.

- Tubeworms. Giant tubeworms (Riftia pachyptila) live near hydrothermal vents in the ocean floor.
- Giant and Colossal Squid. Both the giant squid (Architeuthis dux) and the colossal squid (Mesonychoteuthis hamiltoni) spend most of their lives in the deep ocean.

How is the profundal zone different from the benthic zone?
The Profundal Zone is the zone of a body of water that extends from the surface to some depth where all light can no longer penetrate. In contrast, the Benthic Zone is the bottom-most layer of a body of water, extending from the seabed or shoreline down to any point where it meets with an underwater obstruction (such as rocks).
What kind of animals live in the profundal zone?
Some other examples of animals that live in the Profundal zone are shrimp, crabs, worms, and amphipods Animals that live in the Profundal Zone are typically small and have a lot of adaptations to survive. The profundal zone is located at the bottom of lakes or oceans and can be found several tens of meters below sea level
