Oceans We all know that our Planet earth is Blue

Planet i.e. main composition is water. We have about 71% of water and out of

which we have 97.5% saline water which we called a sea, a part of the ocean.

An ocean is a body of saline water that composes a large part of a planet's hydrosphere.

Its area is 361 million sq.km and has an volume of 1.3 billion cu.km

What is Ocean Life Ocean life is refer to as the living

organisms which are bounded to their marine life.

These organisms may belong to Animals, plants, Micro-Organism, Reptiles and other creatures.

The discovery of life in the ocean is still a mystery, we have achieved things working in the outer space but still we don’t know much about our own BLUE PLANET.

EPIPELAGIC(Sunlight zone)

The uppermost layer of the world's oceans is bathed in sunlight during the daytime. This bright ocean layer is called the sunlit zone or the epipelagic zone.

In clear water, the euphotic zone can be quite deep; it can be only 50 feet deep.

On average, it extends to about 660 feet (200 meters); the depth of the ocean averages about 13,000 feet or 4,000 m.

The temperature in this zone ranges from 104 to 27 degrees F.

Angel Fish

Angelfish are brightly-coloured, flattened fish that live in shallow warm waters.

Page 10: The Ocean Life

Clown fish Clown fish are

small fish that live among this layer.

The anemone's tentacles kill other fish that touch them, but the Clown fish seems to be immune to its poison.

Page 11: The Ocean Life

Blue fin Tuna The Blue fin Tuna is

a large bony fish and is the largest tuna.

The Bluefin Tuna lives for about 40 years.

Found widely in the northern Pacific Ocean and locally in the south.

Page 12: The Ocean Life

MESOPELAGIC(Twilight zone)

The Mesopelagic Zone is the second zone of the ocean layers.

Extending from 200 meters to a 1000 meters.

In this zone there isn't almost any sunlight that penetrates these depths.

It's also called the Twilight zone or the Middwater zone, most of the deep sea fishes are living in this zone.

Page 13: The Ocean Life

Cuttlefish Cuttlefish are marine

animals of the order Sepiida.

Cuttlefish have an internal cuttlebone, eight arms and two tentacles furnished with which they secure their prey.

They generally range in size from 15 cm to 25 cm with the largest species, Sepia apama, reaching 50 cm in length and over 10.5 kg in weight.

Page 14: The Ocean Life

Swordfish The Swordfish offers

a very interesting body.

They have the long bill that looks similar to a sword and that is where their name derives from.

They can be up to 15 feet in length when fully mature. They can weigh up to 1,400 pounds so anyone fishing for them will have a challenge on their hands.

Page 15: The Ocean Life

Eels Eels are elongated

fish, ranging in length from 5 centimetres in the one-jawed eel to 4 metres.

Adults range in weight from 30 grams to well over 25 kilograms.

These are from chordata phylum.

Page 16: The Ocean Life

BATHYPELAGIC(midnight zone)  The bathypelagic zone

or midnight zone can be as deep as 20,000 feet. 

 No sunlight reaches this zone so it is freezing and completely dark.  It also has a very intense water pressure which can be as great as two tons per square inch! 

Some organisms in this zone are vampire squid, giant squid, amphipod, slime stars, snake dragon fish, anglerfish, oarfish, gulper eel.  The sperm whale even dives to these depths to search for food.

  Only about one percent of all ocean species live in this zone, and some don’t have eyes!  What a tough life.

Page 17: The Ocean Life

Gulper Eel The gulper eel, is

one of the most bizarre looking creatures in the deep sea.

Its most notable attribute is the large mouth. This enormous mouth is much larger than the eel's body.

The gulper eel can swallow an animal much larger than itself.

The gulper eel feed on cephalopods (squid) and other small invertebrates.

Page 18: The Ocean Life

Vampire Squid But in spite of its

monstrous name, its is a small creature, growing to only about six inched in length. 

The vampire squid has large fins at the to of its body that resemble ears.

The vampire squid has a very gelatinous form, resembling a jellyfish more than the common squid. It can swim surprisingly fast for a gelatinous animal.

Page 19: The Ocean Life

Giant Tub Worm These giant tube

worms grow up to eight feet (over two meters) in length and have no mouth and no digestive tract.

They depend on bacteria that live inside them for their food.

Giant tube worms reproduce by releasing their eggs into the water to be fertilized. After hatching, the young larvae swim down and attach themselves to rocks.

ABYSOPELAGIC(Abyss)

The abyssal zone is the abyssopelagic layer or pelagic zone

At depths of 4,000 to 6,000 meters (13,123 to 19,685 feet), this zone remains in perpetual darkness and never receives daylight.

It is the deeper part of the midnight zone which starts in the bathypelagic waters above.

Page 21: The Ocean Life

Sea spider Sea spiders, also

called Pantopoda. They are found

especially in the Mediterranean and Caribbean Seas, as well as the Arctic and Antarctic Oceans.

They are common around the site of the titanic.

They are ranging in size from 1 to 10 millimetre to over 90 cm in some deep water species.

Page 22: The Ocean Life

Tripod fish Tripod fish, are a deep-

sea benthic fish found at lower latitudes.

The tripod fish has long, bony rays that stick out below its tail fin and both pectoral (chest) fins.

Even though the fish’s body is 36 cm long, its fins can be more than a meter .

Most of the time, the tripod fish stands on its three fins on the bottom of the ocean.

Page 23: The Ocean Life

Black swallower The black

swallower, is a species of deep sea fish . And is notable for its ability to swallow fish larger than itself .

The black swallower feeds on bony fishes, which are swallowed .

The black swallower is a small fish, with a maximum known length of 25cm.

HADALPELAGIC(Trenches)

The Hadalpelagic/ Hadopelagic Zone is the deepest portion of the ocean extending from just over 19,000 feet deep to the ocean's floor.

The pressure is so great at those depths that the National Geographic News website compares it to the weight of 50 jumbo jets piled on top of you.

Despite this enormous pressure and a shortage of oxygen, there is still plenty of thriving life in these dark reaches of the sea.

Page 25: The Ocean Life

Rat tail fish Rattail fish is also known

as a grenadier, these fish were found at 7,000 meters.

Rat-tails have large mouths and a tapering tail which makes them look like giant tadpoles.

They also have a well developed sense of smell.

They swallow up other fish, moving slowing along the ocean floor to conserve energy as they hunt.

Page 26: The Ocean Life

Amphipods Amphipods are

soft-shelled crustaceans resembling large fleas.

They eat debris from decaying plant and animal matter that floats to the bottom.

They are most important as a food source for the larger animals that inhabit the hadal zone.

PLANTS IN

OCEAN

Page 28: The Ocean Life

Duckweeds Duckweeds, are

aquatic plants which float on or just beneath the surface of still or slow-moving fresh water bodies and wetlands.

These plants are very simple, lacking an obvious stem or leaves.

Page 29: The Ocean Life

Algae Algae are a very

large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms such as the giant kelps that grow to 65 meters in length.

Page 30: The Ocean Life

Seaweed

Seaweed is a loose colloquial term encompassing macroscopic, multicellular, benthic marine algae.

The term includes some members of the red, brown and green algae.

Ocean pollutionPollution in the ocean is a major

problem that is affecting the ocean and the rest of the Earth, too.

Pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources.

People should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution.

Page 32: The Ocean Life

OIL SPILL An oil spill is the release

of a liquid petroleum hydrocarbon into marine areas, due to human activity, and is a form of pollution.

The oil is released into the ocean or coastal waters.

Oil spills may be due to releases of crude oil from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined petroleum products.

Global Warming The impacts of climate

change , acidifying oceans, coral bleaching and habitat loss are the biggest cause of decline in ocean health, and the hardest to solve.

"The effects are all around … If we don't do something quickly, the oceans in 50 years won't look like they do today."

Page 35: The Ocean Life

Human Interference

Humans are really responsible for spoiling the ocean Ecosystem.

The main reason behind it is the exponential increase in the human population and increase in the fishery goods.
