Cetacean Superlatives |
|
The
largest cetacean is the blue whale. In fact, the blue whale is likely
the largest animal ever to
have lived on earth. A length of over 110 ft. (33m), and a weight of 190
tons have been recorded.
The smallest cetaceans are Hector's dolphin (above left), Commerson's
dolphin (above right),
Franciscana dolphin, and Tucuxi
dolphin. These dolphins average 4-6 ft. (1.2-1.8m). |
The largest dolphin is the killer
whale,
often referred to as an Orca whale (right).
Adult killer whales weigh 3-9 tons, and
are 18-32 ft. (5.5-10m) in length. Pods or
groups of killer whales may contain 150
whales or more. Killer whales are one
of the most wide-ranging mammals on
earth. Killer whales are located in all
oceans, particularly in the polar regions. |

Did You Know?
Dolphins are small whales, and
dolphins are very ancient creatures. According to fossil evidence,
scientists say the modern dolphins first appeared on earth during the Miocene period, 25 million
years ago. Rare dolphin species live in rivers in the Amazon and China, but most
dolphins live in the
temperate oceans . There are 26 recognized species of Delphinidae (dolphin), and
dolphins are the
most diverse family of the Cetaceans. Cetaceans comprise all whales, porpoises, and
dolphins.
|
The first recorded studies of
dolphins and dolphin behavior, was undertaken by the ancient
Greek philosopher Aristotle (384-322 BC). In Historia Animalium (The History of Animals),
Aristotle was the first to
correctly claim that dolphins were mammals like us. He noted that
dolphins bore their
young alive, dolphins suckled their young, dolphins breathed air, and
dolphins communicated by underwater dolphin sounds.

People and dolphins have had a
special bond for centuries. During the 20th Century the navies
of Russia and the United States carried out extensive maneuvers with dolphins, who acted
as underwater couriers for the navy. Generally, dolphin missions were affixing bombs to enemy
ships.
|
In October 2000 Russia retired most of their dolphins. These Russian navy dolphins now swim
with sick children, to help them recover from their illness. Recent studies have shown
that
dolphins have remarkable curing powers, especially with small children.

Did You Know?
Dolphins are sociable, and
dolphins are very
protective of their families and young. Dolphins are also
known to be guides and protectors of people. There are many well documented stories
throughout history that tell of ancient mariners who are guided to shore or safety by dolphins.
Dolphin insignias were commonly used on ancient ships for protection. Modern ships such as Jacques
Cousteau's Calypso research vessel, also used the dolphin as their ship's insignia.
|
The Roman historian Pliny the Elder, tells the story of a boy who rode the back of a dolphin
called Simo. The boy would ride the dolphin from Hippo, a small Roman
settlement in Africa.
Roman coins dated at 74 BC., show this dolphin scene. There is a similar
story from Greece about a
dolphin called Lassos, who fell in love with a boy, and took him
far out to sea for dolphin rides.
As recently as October 2000, it was reported that a small boy
drowning off the coast of Italy
was rescued and brought ashore by a dolphin.

"The voice of the dolphin
in air is like that of the
human, in that they can
pronounce vowels, and
combinations of vowels."

Historian and Philosopher.

"Dolphins may well be
carrying information as
well as functions
critical to the regeneration
of life upon our planet."
Buckminster
Fuller,

"Dolphins have new
understandings, that seem
to lie just beyond our
present knowledge. There
may be a common thread
of consciousness' between
man and dolphin."
