ATLANTIC

1. Lemon Shark
2. King Penguin
3. Seahorse
4. Killer Shark
5. Walrus
6. Narwhal

3. Lemon Shark
• The species occupies
shallow waters not far away
from the shore.
• Their name comes from the
yellow brown to olive green
colour of their torso.
• They eat bony fish,
seabirds, smaller sharks,
crustaceans and molluscs.
• These sharks can grow as
heavy as 250 kilograms and
attain a length of 2.5 to 3
metres.

4. King penguin
• It is the second largest
penguin species and it lives in
the southern part of the
Atlantic.
• It feeds primarily on fish and
sometimes on squid.
• The penguin can dive to
between 100 and 300 metres
• . It is a flightless bird like
other penguins and it either
walks or slides on ice.

5. Seahorse
• A sea horse is a bony fish and it
belongs to the same class with
other fishes
• They lack teeth and a stomach
hence they feed by sucking
prey through a fused jaw
• They consume plankton and
little crustaceans. They are
able to camouflage by
changing colour.
• Their breeding behaviour is
peculiar since it is the male
that gives birth.

6. Killer shark
• The killer whale is also called the orca
whale and it is the largest animal
from the family of dolphins.
• They are carnivorous and prey on
almost all animals including sea birds,
seals, fish, marine mammals, sea
lions and squid.
• There is no known natural predator
of this species. The adult killer whale
can reach a length of 9 metres and an
average weight of 3,600 to 5,000
kilograms.

7. Seal
• The Atlantic walrus species is mostly
found between the Canadian Arctic
to the east and the Russian Arctic to
the west.
• There are about 25,000 walruses in
this region with the number of adult
walruses diminishing continuously.
• The animals are very social and are
often found in groups.
• They feed on small invertebrates
and their life expectancy is between
30 and 40 years.

8. Narwhal
• The tusks on the animals are usually
overgrown left canines.
• On average, these animals can weigh
between 800 to 1,600 kilograms and
attain a length of between 3.95 and 5.5
metres.
• They use their tusks as sensory organs.
• They also use echolocation.
• They feed cod and halibut, shrimp and
squid found in Greenland.
• They are threatened by walruses,
polar bears, killer whales and humans.

9. Animals living under the Atlantic ocean.
1. Kelp
2. Phytoplankton
3. Sea grass
4. Thong weed

10. Kelp
• Kelp are large, brown seaweeds
that live on rocky shores of the
ocean.
• Kelp contains over 70 minerals,
vitamins, proteins, enzymes and
trace elements.
• Ascophyllum nodosum is a
variety of kelp that is found most
commonly in the Atlantic Ocean.
• The variety of kelp is often
collected on rocky shores and
used for fertilizer.

11. Phytoplankton
• Phytoplankton is naked to the
human eye and grows abundantly
in many oceans.
• Like plants, phytoplankton requires
sunlight, nutrients and water to
grow.
• These plants are single-celled and
are floating plants. Many small fish
and whales eat phytoplankton.
• Phytoplankton includes seaweed
and algae, which can both be found
in the Atlantic Ocean.

12. Seagrass
• Seagrasses live underwater and are
flowering plants.
• Seagrasses help maintain water
clarity, provide habitat for many
fish and are food for many marine
animals.
• Approximately 52 different species
of seagrass exist.
• Seagrass leaves provide protection
for small marine animals, as they
can hide from predators by ducking
behind the leaves.

13. Thong weed
• Thong weed can be found on
exposed shores or around kelp.
• The fronds are small, mushroom-
shaped buttons that grow into
long, strap-like leaves.
• The buttons are less than an inch
in diameter and the leaves will
grow from the center of the
button up to six feet in length.
• This plant will only live for
approximately two to three years
and is olive-green in color.
