Their Body Parts
• Dolphins have many body parts but many people do not know the real
names of them. Can you name them all?

Facts
• There are 36 species of dolphins found in the world.There are 32
marine dolphins, and 4 river dolphins. They live mainly in saltwater
such as the oceans but some of them live in freshwater and they are
able to do very well there. They tend to live in the shallow water by the
coast and they tend to live in warmer locations. The name dolphin
comes from the word womb, and it is believed to be the Greek saying
for fish with a womb You may hear dolphins referred to by various
names. The young are called calves and the female adults are cows.
The male adults are bulls and a group of them is often called a pod.
Sometimes, you may hear them referred to as school.

facts
The distinctive populations of them stem from the DNA code. What has
been noted is that the different species have vary different codes
which sets them apart from each other far more than researchers had
originally believed. The DNA code is how a discovery was made that
identified a separate species of dolphin than what had been looked at
before.
In 2011, a new dolphin’s species was found in Big City Harbor around
Australia. The Burundian Dolphin is believed to be only in two areas at
this time. There are about 100 of them in Port Phillip Bay around
Melbourne and about 50 more of them in the coastal lakes of
Gippsland which is about 100 miles away.
Studies also indicate that there are differences among the species of
dolphins in terms of their skull size and design. When they are looked
at closely, there are slight variations that have been noted. There are
some other differences too including some having a curved dorsal fin
instead of straight and changes to the snout. Here is some information
about some of the commonly known species. It can be an interesting
though to take one at a time and learn more about them.
The type of dolphin you will see in a given area depends on environmental
factors such as enough food and the temperature. The time of year
also is a factor due to the heavy migrational efforts of most dolphins.
Perhaps the most common of all dolphins is the Bottlenose Dolphin.
This is the one you often see in books, movies, and when you visit an
aquarium. They are very intelligent, easy to train, and they are more
likely to approach humans in the wild than other species.

River Dolphins live in freshwater, and they are found in a variety of rivers
around South America and Asia. They are smaller than most dolphins, with
an average size of about 8 feet when fully mature. They can be various
colors too including brown, gray, or black.
The Roughed Tooth Dolphin is harder to spot out there in bodies of water because they prefer the deeper locations. They
can weigh about 350 pounds and measure about 8 ½ feet long. They have a small head and feature a long beak. They
are also lacking the common crease on the melon that other dolphins have.

facts• The square shaded head of the Risso Dolphin is a telling sign of what
species you are seeing. They don’t have any teeth in the upper jaw
but they have several peg like teeth on the bottom jaw. They are
frequently found in captivity on display because they thrive in such an
environment.
The Striped Dolphin gets its name from the blue and white stripes on the
body. This species is believed to have the highest population as well
as the biggest overall distribution of that population. If you want to be
impressed by acrobatics, check out the Spinner Dolphin. People love
to see them perform both in the wild and when they have been trained
in captivity.
The Common Dolphin is very simple in design, but also very respected in
the early cultures. Researchers have found items from the Ancient
Greek and Roman times. The Dusky Dolphins tend to live in water
that is cooler than the temperatures for other species of dolphins.
They can be found along the coastal regions as well.
The Killer Whale is believed to be the most powerful of the dolphins due to
their size and their strength. They can take down seals effortlessly
which is important due to the significant volume of food that they can
consume on a daily basis. The Pilot Whale can weigh up to 5,000
pounds and be up to 24 feet long. They are believed to be the most
social of the dolphin species. They are also very vulnerable to
