A Little Bit About Dolphins
Dolphins are very intelligent animals. They are able
to train with humans and can achieve many tricks. A
few amazing abilities they have are their intelligence,
their great memories, and the ability to dive great
depths. Dolphins are friendly with humans and are
able to hear commands. They also posses a high
ability to learn, which is partially why they are so
smart and can learn a lot. Throughout this power
point, you will learn about why dolphins are so smart
and a lot about them in general!
Dolphins Are Very Intelligent
Dolphins are very smart creatures, but why are they so
intelligent? Dolphins get their extreme intelligence from having
an unusually big brain. It is also very complex. Their brain
allows them the possibility to swim in all directions, the ability
to swim fast, and to hunt in groups. Dolphins can also
communicate with humans and can be trained.

The Life of a Dolphin
Dolphins live and hunt together in pods (groups) of about 2-15 dolphins.
They are mammals who have the amazing ability to hold their breathes
underwater for as long as seven minutes! They, like us, have to come up
to the surface to breathe. Female dolphins care for their young until they
are old enough to live without her care. Dolphins stay warm in the water
because of a thick layer of fat under their skin called blubber.

Whacking: Dolphins bang their tails against the fish to stun them.
Stunning: The Dolphin makes a “click” sound at the fish, which stuns the prey.
Corralling: When Dolphins herd a school of fish into shallow water, making it hard
for them to escape.

Dolphin Mom and Baby
After born, baby dolphins are nursed by their mothers.
They drink milk provided my their mothers.
Another calf usually helps the mother take care of her baby.
Baby dolphins are cared for by their mothers until they are six years old
and know the skills to surviving.
Dolphin Life Span
The average life span of a dolphin is 25 years.
Dolphins can live up to forty years
Dolphins do not live shorter in captivity, they can actually live
longer since they are provided with medical care.
The oldest current living dolphin is 57 years old!
Typically, female dolphins live longer than male dolphins
Dolphins often die from being preyed on by killer whales and
Dolphins: Endangered Animals
Dolphins are endangered creatures. This is mainly because of us humans. Dolphins
often are killed because of getting caught in fishing nets that are supposed to catch
fish. Also, ocean pollution harms dolphins and kills their prey so they have nothing to
eat. Climate change warms the ocean temperatures and because of this, prey
populations are affected. This affects the ocean food chain and dolphins and other
animals will not have enough food to eat. Overfishing also kills off the food that
dolphins eat. Habitat loss also hurts dolphins. While humans build dams and use boats
to travel, we are taking up the place where dolphins live and we are polluting it. All of
these things are bad for the environment but the good news is, we can help! We can
reduce the amount of pollution being put into the ocean and we can stop overfishing
and only take the amount of fish we need. Take action and remember that dolphins
are living creatures just like us and that we should start caring for them instead of
putting them in harms way.
