Fair Use Notice

Plant Life

Some of the material in this presentation is covered under the Fair Use Guidelines of the copyright Law, Title 17, U.S. code.

Becuase the Aphotic zone is so deep photosynthesis can not coour here, therefore plants dont survive and there is none

Ecological Threats

Aphotic zone

The animals who live around the vents depend of the chemosythesis from the vents to make their food. If the vents runs out all the animals in this area may become extinct

Giant Tube Worms

Forms around Hydrothermal vents

Looks like plants

Squishy center is full of bacteria

Lives solemly on itself

Bacteria feeds on it's blood

Gulper Eel

Worms feed of bacteria

Spawning

Stay anchored to the gorund

Deepest layer of the worlds oceans, and gets no light at all. The depth of this zone usually starts at about 13,000 m.

Extremely large mouth

Almost non-exsistent fins

Eyes detect light not movement

Can swollow animals larger than itself

uses tail for movement

Light at the end flashes pink and red and lures in prey

Solution

Average Temperature

Gupler Eel

use deep sea drills to create more hydrothermal vents in these areas to keep the populations thriving

In the Aphotic zone the temperature is so deep that the temperature is nearly freezing and decreases with depth

Rainfall

Food Chain

Fish

Because this area of the ocean is so deep down, no rainfall occurs here. Falling dead sea creatures rain down from above to give the apotic sone a snow like resemblence

Most animals rely on the carcuses of sperm whales to fall from above for the nutriets and food that they need to survive that can last them up to two years
