2. IntroductionIntroduction
• The Deep Blue Sea-The Behemoth Unstable Sea, The
deep with all its mysteries.
• What is the Sea? It is a mammoth mass of water that
covers a sizeable portion of the planet’s surface- in fact
70% of the planet’s surface!
• The mass of water that covers the earth at times are
called the oceans. It is very interesting to note that the
mass of waters are subdivided into several categories
which most times are used interchangeably.
• The Ocean is a larger expanse of water than the sea.
Seas are subsets of Oceans and are much more saline.

3. OCEANSOCEANS
• There are 5 major Oceans in the World
namely:
• Atlantic Ocean
• Arctic Ocean
• Antarctic Ocean
• Indian Ocean
• Pacific Ocean

4. • It is important to note that these oceans
have several seas within their domain.
• The Atlantic Ocean has 41 different seas
within it. This includes Adriatic Sea,
Aegean Sea, Black Sea, North Sea, and
Caribbean Sea. The following slides gives
some few examples of seas within the
oceans

5. Atlantic OceanAtlantic Ocean
• Adriatic Sea
• Aegean Sea
• Alboran Sea
• Argentine Sea
• Bay of Biscay
• Bay of Bothnia
• Bay of Campeche
• Bay of Fundy
• Baltic Sea
• Black Sea etc

• Andaman Sea
• Arabian Sea
• Bay of Bengal
• Gulf of Aden
• Gulf of Oman etc

9. 5.5. Pacific OceanPacific Ocean
• Arafura Sea
• Banda Sea
• Bering Sea
• Bismarck Sea
• Bohai Sea
• Bohol Sea (also known as the Mindanao Sea)
• Camotes Sea
• Celebes Sea etc

10. • However, among these seas, the most popular
ones are: Sea of Galilee, Adriatic Sea, Arabian
Sea, Persian Gulf, Red Sea, Aegean Sea, Dead
Sea, Caspian Sea, Black Sea, and
Mediterranean Sea.
Oceans play a very important role in the climate of
the world. They carry quite an enormous amount
of heat which affects the temperature of the
prevailing wind in contact with Ocean current.

11. CREATURES OF THECREATURES OF THE
BEHEAMOTH SEABEHEAMOTH SEA
• The sea is known to contain very large
amount & species of animals. In fact, it is
known to contain the largest array of
species. There are also different plant
species. The estimate amount of species
are about 20,000.There are well over
14,500 different types of algae species in
the oceans

12. • These organisms dwell at almost every
depth of water. The types of living
creatures at these depths are being
affected by three major factors-
Temperature, Salinity & Depth.
• All sea animals are divided into 2 broad
categories:

13. • The NEKTON- Animals that are streamlined and can
move from one place to another. They also have a
means of floatation. Among these are Sharks, skates,
dolphins, fishes, sea turtles, penguins & seals.
• THE BENTHOS- These are organisms living at the
bottom of the ocean. Among these are corals, spongies,
ascidians, mollusks or may be crawling like sea-stars,
sea-urchins, crabs, mollusks which crawl at the sea
bottom or may be free swimming in the lowermost layers
of the water (fishes, cuttlefishes, squids). Some of these
organisms use filter mechanism for feeding

16. Box jellyfishBox jellyfish
• Box jellyfish (Chironex fleckeri) are found
mostly in the warm waters north of the
Tropic of Capricorn. Their Stings are
potentially fatal.

17. StonefishStonefish

18. • Stonefish stings are potentially fatal. It is
important to see medical help immediately
from a stonefish sting. Antivenom can be
available to treat the venom.

19. CONE SHELLCONE SHELL
• The cone shell has a small "harpoon" that can
penetrate the skin and cause envenomation.
The venom can very quickly cause life-
threatening paralysis. For first aid , pressure-
immobilization technique should be used & the
patient taken immediately to the emergency
department of the nearest hospital.

20. Blue-ringed octopusBlue-ringed octopus
• Blue-ringed octopus can be found in rock pools,
and bites can occur when people touch them or
stand on them. The octopus shows their blue
markings only when disturbed. Bites from a blue-
ringed octopus are potentially fatal. For
suspected blue-ringed octopus bites, use the
pressure-immobilisation technique, & the
patient taken immediately to the emergency
department of the nearest hospital.

21. VIPER FISHVIPER FISH
• Viper fish (Mesopelagic - found at 80-1600 meters -
about a mile down) are some of the most wicked looking
fish dredged up from the depths. Some of them are black
as night all over with light organs (called photophores) in
strategic places on their bodies, including one on a long
dorsal fin that serves as a lure for the fish it preys upon.
Some viperfish (and many other deep ocean fish
species) don't have any pigment (color) at all - they're
"see through". They also have enlarged eyes,
presumably for gathering as much light as possible
where there is little or no light at all. The light organs
create lights by using a chemical process called
bioluminescence.

24. SEA WASPSEA WASP

25. • Sea Wasps, or box jellies, are not
aggressive. They don't have to be. For
jellyfish, they are pretty fast swimmers (up
to 5mph), dangling their long tentacles in
the surf behind them until something,
usually a fish, gets caught in their
practically invisible tentacles. That's where
all their nematocysts (stinging capsules
contained within cells called cnidocytes
located along the tentacles) are located.
