The
Largest Animal across the WORLD is WHALE itself.
Whales
are the largest creatures to have lived on earth. Like all life, they evolved
in the sea and like many other creatures later moved onto the land during their
early period of development. Eventually however the whales went back to the sea
where the feed was more plentiful and gradually developed to their present
size.

The blue whale Largest Creature on Earth,The blue whale is the largest creature on earth. Its
weight, in rare cases up to 200 tons, and the length of 33 meters. The average
length of 23-29 meters. This is truly a huge animal, just a giant. Previously,
its range was from Antarctica to the Arctic. Whaling nearly wiped out the blue
whale. To date listed in the International Red Book and Red Book of Russia.

The Heart of a Blue Whale is

THE SPERM WHALE
 |
| Jagdeesh's Creative World.in |
Size: 11-18m; 20-50 tonnes
Distribution:
Patchy distribution worldwide, from the tropics to high latitudes near
the edge of the pack ice. Normally, only large males venture to the
extreme north and south of the range. Prefers deep water and usually
found offshore, but also occurs over submarine canyons near the coast.
Diet: Giant squid are the main prey, although octopi and a wide variety of large fish are also taken.
Status: The sperm whale was the
mainstay of the whaling industry, and huge numbers were killed over
several centuries. Against all odds, it is still fairly numerous and is
probably the most abundant of all the great whales.
THE HUMPBACK WHALE
 |
| Jagdeesh's Creative World.in |
Size: 11.5-15m; 25-30 tonnes
Distribution: Widely distributed
in all oceans of the world, from the poles to the tropics. Feeds in
high latitudes during the spring, summer and early autumn, and migrates
to tropical breeding grounds for the winter.
Diet: Schooling fish (including herring, sand lance, capelin, mackerel and salmon) as well as krill and other crustaceans.
Status: Nearly a quarter of a
milion humpback whales were killed by the whaling industry, wiping out
more than 95% of the world population. Fortunately, in recent years,
they seem to be making good recovery in many parts of their range.
THE MINKE WHALE
Size: 7-10m; 5-10 tonnes
Distribution: Virtually
worldwide, from the tropics to the edge of the polar ice, although most
common in cooler waters. Some are migratory, others appear to be
resident. Occurs inshore and less frequently, offshore.
Diet: Mainly krill and small schooling fish.
Status: The minke whales small
size saved it from commercial whalers until relatively recently.
However, now that most of its larger relatives are endangered and
officially protected, it is the only baleen whale being hunted
commercially under the auspices of the IWC. Nevertheless, it is still
the most abundant of all baleen whales.
BRYDE'S WHALE
Balaenoptera edeni
Size: 11.5-14.5m; 12-20 tonnes
Distribution: Warm waters
worldwide. Rarely moving further north or south than 40 degrees, it
occurs both offshore and near the coast. There seem to be specific
pockets of abundance, such as off South Africa, Sri Lanka, Japan, Fiji
and Western Australia.
Status: The history of whaling
for Bryde's whale is largely unknown, because it was not consistently
distringuished from the similar 'Sei Whale' until quite recently.
However, it is likely that some populations have been depleted by
whaling.
THE SEI WHALE
 |
| Jagdeesh's Creative World.in |
Size: 12-16m; 20-30 tonnes
Distribution: Mainly in deep,
temperate waters worldwide, but also found in the sub-tropics and
tropics. Rarely seen close to shore, except in deep water around
islands and most common in the southern hemisphere.
Diet: Small crustaceans, such as krill and cope-pods, and schooling fish.
Status: Heavily depleted by
commercial whaling in some areas, and as a result, the world population
has dropped from an estimated 250,000 to 60,000.
THE FIN WHALE
 |
| Jagdeesh's Creative World.in |
Size: 18-22m; 30-80 tonnes
Distribution: Deep water in
tropical, temperate and polar regions worldwide, but most common in
cooler waters and in the southern hemisphere. Some populations seem to
be resident year-round, but others may migrate between warm waters in
winter and cooler waters in summer. Normally encountered offshore, but
will approach the coast in deep water.
Diet: A variety of schooling fish, krill and other crustaceans and to a lesser extent squid.
Status: The world population was
substantially reduced by commercial whalers and although it is not
believed to be in immediate danger, the population has dropped to an
estimated 120,000.
THE BLUE WHALE
 |
| Jagdeesh's Creative World.in |
Size: 21-27m; 100-120 tonnes
Distribution: Worldwide, from the
tropics to the poles, although its distribution is very patchy. Some
populations migrate long distances between low-latitude winter breeding
grounds and high-latitude summer feeding grounds, but others appear to
be resident.
Diet: Various species of krill.
Status: The blue whale was hunted
relentlessly from the late 19th century. So many were killed that some
stocks may never recover. Others, such as those off California and
Mexico have begun to show encouraging signs of recovery.
BELUGA
Size: c.3-5m; 0.4-1.5 tonnes
Distribution: Found only in
seasonally ice covered waters of the sub-arctic and arctic. Mostly in
shallow coastal waters but will enter estuaries and even rivers.
Diet: A wide variety of fish as
well as crustaceans, squid, octopus and molluscs. Believed to feed
mostly on or near the bottom.
Status: Belugas have been hunted
for centruries. Pollution is a serious threat in some regions with
a population of 50,000 - 70,000.
FALSE KILLER WHALE
Size: 4.3 - 6m; 1.1-2.2 tonnes
Distribution: Widely distributed
in tropical, sub-tropical and warm temperate waters worldwide. Prefers
deep water and normally encountered offshore.
Diet: mainly fish and squid. Also know to attack dolphins.
Status: Small numbers drown in
fishing nets or are hunted for food. Others are shot or driven ashore
by fishermen, especially in Japan, who regard them as competitors. A
few are also captured for marine parks. Total numbers are unknown.
PILOT WHALES
Globicephala macrorhynchus (short finned)
Size: 3.8 - 6m; 1.8 - 3.5 tonnes (long finned) 3.6 - 6.5m; 1 - 4 tonnes (short finned)
Distribution: The long finned
pilot whale has two distinct populations: cool waters of the southern
hemisphere and cool waters of the North Atlantic. The short finned pilot
prefers warmer waters and is found worldwide. Both species prefer deep
water.
Diet: Both species feed mainly on squid.
Status: Large numbers of long
finned pilot whales are killed every year in the Faroe Islands and
smaller numbers in other parts of the world. Smaller numbers of the
short finned whales are killed in Japan, the Caribbean and elsewhere.
Both species are still fairly comon in many parts of their range.
ORCA (KILLER WHALE)
Size: 5.5 - 9.8m; 2.6 - 9 tonnes
Distribution: Despite its rather
patchy distribution, the orca is one of the most wide ranging mammals on
earth. It occurs in all seas and oceans, from the equator to the poles
and from near shore to deep sea.
Diet: Squid, fish, sea turtles,
birds and marine mammals. No animal is too large - even adult blue
whales are hunted on occasion.
Status: Shot by fishermen in some
parts of the world. Live captures for oceanaria have occurred in
several countries, most recently Japan and Russia.
