Dolphins come in 33 types including marine, river, and killer whales. They have smooth skin, a dorsal fin, flippers, and a fluke tail. Color varies by type from gray to white to black. Dolphins are social, intelligent animals that hunt in groups but eat individually. They eat fish, squid, and shrimp totaling 4-5% of their body weight daily. Dolphins communicate well with humans and may protect people from sharks.

The Dolphin
Story

2. Dolphin’s Appearance
• Dolphins have 1 dorsal fin like
a sharks, two flippers and a
tale called a fluke which is just
like a shark’s tail.
• Their skin is very smooth but
their skin is also very sensitive
so they can get hurt and
damaged easily.
• Believe it or not but they can
even be sunburned.
• They don’t have a nose but
instead have a blowhole which
allows them to breathe easier
when they come up for air
because dolphins need to
breathe air too.
• Dolphins also have ears,
only it’s not sticking out
like us humans but is a
tiny hole that allows them
to hear well.
• Color varies for each type
of dolphin which you’ll
read about in the next
slide but they mostly have
gray, white and black
coloring.

3. Types of Dolphins
• There are 33 types of dolphins
• 3 types: Marine dolphins, river dolphins, killer whales and porpoises.
• All dolphins range in size
• for example the Marine Dolphin Maui’s Dolphin is the smallest kind of
dolphin in the world. The killer whale is the largest type of dolphin in the
world.
• The marine dolphins are the most common dolphins seen in oceans and
at aquariums. They are different shades of grays and some grayish white
colors and dark gray colors.
• River Dolphins are found in salt water rivers. River dolphins are usually
light colored such as light blue, light gray, white and even silver.
• Porpoises are found in small groups in the oceans; as for their coloring
they pretty much are more of a coloring that’s not to dark and not to light
of browns, whites, grays and blacks.

4. Behavior of the dolphins
• Most of the time dolphins are very
friendly, playful, acrobatic and
intelligent.
• Dolphins are also very smart for
animals because they have the
mind most two year old humans
have.
• They have a closer relationship
with humans than most sea
creatures which is why dolphins
will protect humans if there are
sharks nearby
• Dolphins are mostly seen living
and traveling with groups of
dolphins.

5. A Dolphin’s Diet
• Dolphins eat a wide variety of
fish mostly Capelin and
Herring, squids and shrimp.
• Dolphins eat a lot of food,
adults eat 4% to 5% of their
body weight in food per day.
• Strangely dolphins don’t chew
their food but swallow it whole
• To get their food most dolphins
hunt in groups, yet they all eat
individually
