Whales

Whales are large, magnificent,
intelligent, aquatic mammals.
They breathe air through
(blowholes) into lungs (unlike
fish who breathe using gills).
Whales have sleek,
streamlined bodies that move
easily through the water. They
are the only mammals, other
than manatees (seacows), that
live their entire lives in the
water, and the only mammals
that have adapted to life in the
open oceans.
Whales breathe air. They are
NOT fish. They are
mammals that spend their
entire lives in the water.
Whales

Whales have hair
(although they have a lot
less than land mammals,
and have almost none as
adults),
 Whales are warmblooded (they maintain a
high body temperature),
 Whales have mammary
glands with which they
nourish their young,
 Whales have a fourchambered heart.
Penguins

Penguins are birds. Most of
them live in the sub-Antarctics
and on Antarctica. However, the
Galapagos penguin lives
around the equator.
There are no penguins on the
North pole, nor are there ice
bears on the South pole.

Unlike most other birds,
penguins can't fly. They
waddle on land and swim in
the sea. When swimming fast,
they jump out of the water
every few meters, just like
dolphins do. This is called
porpoising.
Skin and colour of penguins.


The top layer of a penguin's
skin is made of thousands of
small, stiff feathers. The air
between the feathers is good
insulation. To make their 'coat'
even more water- and
windproof penguins spread
some oil on it. Below the
feathers is a thick layer of
blubber to keep the penguins
warm.
Once a year, penguins shed
their feathers and grow new
ones. This is called melting. The
old feathers come off in patches
and at the same time new
feathers grow. All penguin
backs are black and all bellies
are white. This has to do with
swimming camouflage: the
black back looks like the
bottom of the ocean and the
white belly looks like the water
surface.
Clown Fish

Clown Fish are commonly
found in the warm waters. The
Pacific Ocean, the Red Sea
and the Indian Ocean are
some places where Clown
Fish abound. The most
common home for the Clown
Fish is among the tentacles of
the Sea Anemone. It’s a
curious quirk of nature that the
tiny Clown fish is able to live
without getting stung by the
tentacles of the Anemone. The
fish actually uses the Anemone
to save it from predators.
Turtles

Adult turtles may go to different
feeding grounds altogether, and
when sexually mature will travel
to breeding areas to mate.
Gravid females come ashore on
tropical nesting beaches to lay
their eggs – a hundred or more
at a time, in nest pits that they
painstakingly excavate with
their hind flippers. The process
of finding access to the beach,
hauling a huge body built for
aquatic life onto gravity
encumbered land, then crawling
with flippers made for water
across wide swaths of sand,
rock, and berms, is
extraordinarily difficult.
Sea Lions

Sea Lion, intelligent, slenderbodied seal, well known for its
balancing acts as a circus
performer and its presence in
almost every zoo. In the wild,
these shore-living seals are
found along many areas of
North America’s western coast,
from British Columbia
southward through the United
States to the Tres Marias
Islands off of Baja California,
Mexico. Adult males, called
bulls, average 360 kg (800 lb) in
weight and 2.1 m (7 ft) in length.
Females, or cows, are smaller,
with an average weight of 110
kg (250 lb) and an average
length of 1.8 m (6 ft). Both
sexes have chocolate-brown
coats and doglike muzzles
Sharks


What are sharks?!
Sharks are amazing fish that
have been around since long
before the dinosaurs existed.
They live in waters all over the
world, in every ocean, and
even in some rivers and lakes.
Unlike bony fish, sharks have
no bones; their skeleton is
made of cartilage, which is a
tough, fibrous substance, not
nearly as hard as bone. Sharks
also have no swim bladder
(unlike bony fish).
Sharks

Some sharks live near the
surface, some live deep in the
water, and others live on or near
the ocean floor. Pelagic sharks
include the great white shark,
the basking shark, etc. Benthic
sharks include the zebra horn
shark, the wobbegongs, and the
angelshark, which usually have
flattened, camouflaged bodies
that let them hide in the sea
bed. Some sharks even venture
many miles up into the fresh
water of rivers like the
Mississippi in the USA and the
Amazon in Brazil. The bull
shark (Carcharhinus leucas)
sometimes ventures into fresh
water.
Dolphins

All dolphins are toothed
whales belonging to the suborder, odontocetes, of the
order cetacea (see section on
humpback whales for more
information). As a group,
dolphins are often referred to
as "small" cetaceans, even
though some of them are quite
large, attaining lengths of over
20 feet. In addition, although
the terms dolphins and
porpoises are often used
interchangeably, they really
refer to two different types of
animals.
Dolphins

Most dolphin species are
about 6 ft in length, the
males averaging 4 to 8 in
longer than females. One of
the largest dolphins is the
bottle-nose dolphin which
can reach over 9ft in length
and weigh 440 lbs. The
smallest species is the
buffeo, found in the Amazon
River. The buffeo rarely
grows over 3.9 ft in length
and 66 lbs in weight, really
smalled compared to the
bottle_nose. The primary food
is fish, mostly things like
herring, mackerel, and
sardines.
Dolphins

The body is sleek and
smooth and the hairless
skin is rubbery to the
touch. Most species
have jaws that protrude
into a beak like
snout. Above the upper
jaw is a large mass of fat
and oil-containing tissue
forming the so-called
"melon" that looks much
like a bulging forehead.
