Transcript of Ocean Layers

Salt Water Oceans
pacific ocean
Epipelagic aka Sunlight zone
Mesopelagic aka Twilight zone
Bathypelagic aka Midnight zone
Abyssopelagic aka Abyss
Hadalpelagic aka Trenches
Epipelagic zone
(Sunlight zone)
Mesopelagic zone
(Twilight zone)
The first layer from 0m to 200m
Enough light for photosynthesis
Average surface temperature 17degrees Celsius
Wind keeps layer mixed
The heat is responsible for wide range of temperature
It is the second layer from 200m to 1000m
There is only faint light insufficient for photosynthesis
Average temperature between 12-4 degrees Celsius
Water moves slowly here
Great diversity of strange fish
Bathypelagic zone
(Midnight zone)
The third layer from 1000m to 4000m
Only visible light from animals
The average temperature is about 4 degrees Celsius
Average Psi is 5850
Most animals here are red,black or transparent due to lack of light
Abyssopelagic zone
This is the fourth layer from 4000m to 6000m
The average temperature is around 2-3 degrees Celsius
There is no light at all here
The name came from the greek word meaning "no bottom"
Three quarters of the ocean floor is in this zone
Hadalpelagic zone
The fifth and final layer from 6000m to anything greater
Average temperature just above freezing
The pressure is 8 tons
The deepest point was found in Mariana Trench
Even with extreme pressure invertebrates live here

Photosynthesis is when a plant turns light energy it gets into chemical energy, then that can be used to fuel the organism. The chemical energy is stored and later oxygen is released as waste.
Hammer Head Shark
Attack their prey with their whole head
hammer head shark: http://library.thinkquest.org/08aug/01316/Hammerhead%20Shark.html
Turns itself inside out to use its spiky tentacles
They are crustaceans that hide using their red transparent bodies
The squid is transparent and uses photosphore to lure prey
Photophores are light-emitting organ that certain organisms have in the deeper parts of the ocean
An echinodem that is connected to the sea cucumber and eats mud like earthworms
angler fish
bigscale fish
Has oversized scales and a bony plated head
Relatives of the jellyfish they use lures to catch their prey and to save energy
Well known for their enormous mouth and flashlight like lure
spook fish

The only known organism to use mirrors in place of eyes
tripod fish
Named for three extra fins that let them "stand", they can also reproduce by themselves
deep sea medusa
Catches prey with tentacles and digests in center cavity
basket star
They sit on bottom of sea floor ,raise their tentacles up and try to catch falling particles
gulper eel
Gigantic mouth works like hinges so they feed like pelicans, their tail also propels them
snake dragon fish
They have large eyes, sharp teeth and wide mouth with a glowing organ
brittle star
They hide using camouflage during the day and come out to eat at night
snipe eel
They use their curved jaw to trap prey
hatchet fish
They are mostly deep bodied and have a sharp "blade" along the bottom of their body
black dragon fish
Long and thin with two rows of lights on either side of their body
tube worms
They lack a mouth and guts so they absorb nutrients directly from water
They are single-celled organisms that shape themselves according to their environment
Single-celled organisms that are related to algae that they also "farm" in their shells
moray eel
They can change colour to hide and can change the temperature of their body
sea cucumber
If others try to eat them they will let their guts out as a distraction
They have a soft body with two hard shells and they change their gender over time (male-female)
blow fish
When scared or threatened they will blow up, they are also poisonous in their liver, muscles, skin and ovaries
