The killer whale (also none as a Orca) is actually a type of dolphin.
Female dolphins are called cow's, male dolphins are called bull's and children
dolphins are called calves.
Dolphins are very intelligent
and they seem to be well loved by humans. This aquatic mammal has been able
to fascinate us in a variety of ways. They are curious, form strong bonds
within their pod, and they have been known to help humans in a variety of
circumstances including rescues and with fishing.
There are 43 different species of dolphins that have been recognized.
38 of them are marine dolphins which are those that we are the most aware
of and 5 of them are river dolphins. It can be very interesting to look
at each of these species uniquely versus dolphins as a whole.
They are very entertaining due to the leaps that they make out of the
water. Some of them leap up to 30 feet in the air as they do so. They have
to come to the surface to for water at different intervals to get air. This
can be from 20 seconds to 30 minutes between when they get air. The body
of the dolphin is grayish blue and the skin is very sensitive to human touch
and to other elements that could be in the water.

Even though dolphins have 100 teeth, they don’t use them for eating. They
do use them to get the fish though and then they swallow them. They can consume
up to 30 pounds fish per day. They usually work as a team in their pod to
get the school of fish surrounded and balled up. From there, they can plow
through the middle and eat plenty as they do so.
They take turns doing this so that all that participated get to dine on
the fish. This is just one of the many different types of feeding strategies
that they may take part in. They do what is necessary to get the food for
the pod members. It can include jumps, zig zag patterns, circles, and a combination
of efforts to get the job done.
“Dolphins have been interacting with humans for as long as we have known
of their existence”.
Most of the species of dolphins live in saltwater but there are some that
are able to do well in the freshwater locations. They are mainly found in
the freshwater of the Amazon River. They are easily seen by humans as they
tend to stick to the swallow locations of the water.
It is amazing the difference in size of the various species of dolphins.
The larger ones can weigh about 11 tons and be close to 30 feet long. The
smaller ones are about 90 pounds and 4 feet long. Between those two spectrums
you will find all weights and lengths. The species as well as their location
play a huge role in their overall size.
The body of a dolphin is designed to help them move through the water
quickly and without exerting huge amounts of energy. They rely on their
pectoral fins and the fluke (tail) to help them navigate through the water.
Through extensive research, echolocation has been identified as a key
element of dolphin life. It allows them to communicate in the water by identifying
sound waves. It is a complex ability that stems from the melon that is located
in the head of a dolphin. All dolphin species have a blowhole.
Dolphins have very good vision, and they are able to see what is around
them both in the water and when they are above the surface of it. They have
excellent hearing too, with the ability to hear about 10 times better than
humans. The sense of smell isn’t well developed for them though. The sense
of touch is very sensitive for dolphins and they use it for bonding within
