Transcript of Epipelagic Zone

Epipelagic Zone
(Sunlight Zone)

Temperature
In the epipelagic zone, temperature reaches as high as 97º Fahrenheit 36º C in the Persian Gulf. Near the poles, it gets as cold as 28º F -3ºC.


Water Pressure
Water pressure in the epipelagic zone is 88 psi (pressure per square inch)
Seals
Light
The epipelagic zone is also known as the sunlight zone. It gets this name because, being the top layer of the ocean, this is where most of the visible light exists. Since it gets a lot of light, it also gets heat. The heat provided from the light is responsible for the wide range of temperatures in this zone.

Mating
Mating: the male gets aggressive towards other males so they can win a female seal interest. Males usually mate with as many female seals as they possibly can during mating season. They mate in water and land.
Feed
Feeding: They find their food in the ocean. But the seal pups usually drink milk from the mothers body for the first month of their life then they’re on their own.

Sea Turtles
Mating
Mating: When mating two or more males can court a single female. The males use their enlarged claws on their front flippers to grasp the females shell when mating. After mating females usually come back ashore.


Feeding
Sea turtles are omnivores. They eat crabs, shrimp, lobster, urchins, jellies, algae, and fish.


Sea Grass
Mating
Sea grass reproduce both sexually and asexually
Feeding
Sea grass feed on the nutrients present in the sediment in the sea bed floor.

Mangroves
Mating
Mangroves are viviparous (bringing forth live young), rather than producing dormant resting seeds like most flowering plants.

Feeding
Mangrove survives on the nutrients the roots carry up from under the water.

Unique Things about this Zone
Ninety percent of the oceans animals and plants live in the epipelagic zone because of its warm temp. and sunlight.

The depth of this zone depends on the clarity or murkiness of the water. In clear water, the euphotic zone can be quite deep; in murky water, it can be only 50 feet deep. On average, it extends to about 660 feet

Distance
How large is the zone?
The epipelagic zone extends 200 meters
Distance from the surface?
Starts at the surface and goes down 200 metres.
