The Fascinating World Of Dolphins

Since dolphins swim in the water many people think that they
must be fish. However, dolphins are in fact warm-blooded
mammals that breathe air and give birth to baby dolphins
rather than lay eggs. This fact alone makes dolphins unique
creatures, but they also have many more characteristics that
make them one of the most interesting animals on the planet.

Dolphins and some whales are cetaceans and part of a whale
group known as odontocetes. Basically this means that they
all have teeth. Whales that don't have teeth to eat with
are mysticetes. Dolphin teeth are cone-shaped, and it's
these teeth that set them apart from other sea animals.

You'll be able to find dolphins living in tropical, warm
waters around the world. Unknown to most people is that
there are a few species of dolphins that live in rivers and
freshwater. These dolphins, however, are few in number and
are now considered to be on the endangered list.

Fifty-seven different species of dolphin make up the
world's population today. Dolphins have sleek bodies and
their noses, called "rostrum", are long and beak-like. Many
of us think that dolphins and porpoises are related, when
in fact they are not. One thing that makes them different
is their teeth. As mentioned the dolphin's are cone shaped
and the porpoise have teeth that look more like spades.
This enables them to dig for food among rock. The other
major difference is the fact that porpoise are able to live
in water that's colder than a dolphin can even tolerate.

One of the most common and well known species of dolphins is
the Orca, also known as the killer whale. This large dolphin
is considered to be fearless in the water, dominating the
list of sea animals that people think of when they think of
ferocious creatures.

Dolphins have a long gestation period when it comes to the
birth cycle of their young. The female dolphin will be
pregnant for twelve months after which time she will give
birth to one baby dolphin, called a "calf". Most baby calves
will weight about 30 to 40 pounds and will be approximately
30 inches long. The mother dolphin will nurse her calf for
the first two years of its life.

Unlike other species of animals where the mother gives birth
and the young leave her side after a short period of time,
the dolphin calf will stay with its mother for five to seven
years. During this time the young dolphin will learn many
skills from its mother, including how to feed and how to get
along with other dolphins.

Dolphins live and move around in groups known as "pod". The
males stay detached and do not take any interest in
parenting. It is the females who rear the siblings and do
all the nursing. The female does all the interaction with
the calves and males do not involve themselves in community
life other than impregnating the females.

The dolphin continues to be one of the most fascinating
animals in the world. This has a large part to do with its
intelligence and incredible curiosity. These animals love to
interact with man whenever they can, chirping in their
native dolphin tongue about events in the water that we'll
never understand.
