How do Dolphins Sleep?

Dolphins sleep by shutting off one half of their brain at a time.
They rest just like we do
when they take a break from swimming and playing
in the ocean’s waves.
They can even swim while they’re asleep
keeping watch over their pod so they don’t get lost.
Dolphins have been known to sleep with one eye open
in case there’s danger lurking nearby.

One Eye Open

Dolphins sleep with one eye open,
in case they need to swim away.
They’ll drift off to sleep,
but they’re never really far away.

The dolphins stay close together,
forming a protective circle.
They’ll nap for a while,
before swimming back into the sea.

Dolphins Are Mammals

Dolphins are mammals
They need to breathe air
They live in the water
But they come up to the surface
To breathe and jump around
Dolphins are so graceful
And they’re really smart, too
They help people out
In search and rescue missions

Just like us?

Dolphins are mammals just like us
They need air to breathe and they must eat
Just like any other mammal they grow and nurse their young
Dolphins communicate with each other in unique ways
They can be playful and full of fun
But they are also quite intelligent
In the wild they often work together as a team
They’re always a joy to see

Dolphins often work together

Do Dolphins Have Gills?

Dolphins have no gills

But they can hold their breath

They will stay underwater

For quite some time

They can swim so fast

And they’re very smart.

Dolphins know how to play

And they have a lot of fun

They know how to sing and dance

But the best thing about them is that they’re friendly.

Dolphins underwater

How long can dolphins stay underwater?

Dolphins can hold their breath for up to 10 minutes

They are one of the few sea creatures

Who can survive without air for a while

But they have to come up for air eventually

Otherwise they will drown

Dolphins use their echolocation to find food

And to communicate with each other

They are very intelligent creatures

And are part of our eco-system

Dolphins swimming underwater

Born to Swim

Dolphins are born to swim

and love the ocean deep

But how long can they stay

underneath the waves

before they have to come up for air?

Some dolphins can hold their breath

for up to five minutes

Others only a few seconds

It really depends

on how much they need oxygen

They use their blowholes to breathe

And when they’re underwater

They close their blowholes tight

So no water can get in

It’s an amazing thing to see

These creatures of the sea

How they can stay down so long

And not have to come up for air.

Dolphins in captivity

How Many Dolphins Are Kept In Captivity?

How many dolphins are kept in captivity?
Over 3000, it seems, and not enough space.
SeaWorld has them swimming in tanks,
But fortunately, some people care
And try to free these creatures so rare.

Majestic creatures held captive

Dolphins are majestic creatures
Often seen jumping out of the sea
But how many people know
Just how many dolphins are in captivity?

It’s estimated that over 5,000 dolphins
Are held in tanks and pools
Many of them for our entertainment
As we watch them swim and leap

The thought of these intelligent animals
In such cramped spaces is sickening
It’s time to let them free
So they can live as nature intended

Kept in Captivity

How many dolphins are kept in captivity?
Thousands, it seems, and not enough space.
SeaWorld has them swimming in tanks,
But fortunately some people care
And try to free these creatures so rare.

In captivity

In captivity,
many dolphins are kept
against their will
to do tricks for us
and make us smile
but in the wild,
they would be free
to swim and dive and play
and never have to worry
about a concrete tank.

Smart Dolphins

Dolphins are very smart

And can learn tricks easily

They are also very playful

And love to play games.

Where are Dolphins Found in the Wild

Dolphins – fascinating creatures frolicking in the seas

Found in many different parts of the world

In the shallow waters of ocean’s continental shelves

Enjoying tropical and temperate waters,

Some larger species found in colder environments,

Even in the Arctic Ocean.

Playful Nature And Friendly Smiles

Dolphins are truly amazing creatures

With their playful nature and friendly smiles

They always bring happiness to those around them

And we can learn so much from their ways

They always look out for one another

And they never give up hope

Their compassion and kindness is something to be admired

And we could all use a little more of that in our lives

Gentle and Kind

Dolphins are gentle and kind,
These creatures of the sea,
With their playful nature and sweet smiles,
Are a joy to behold.

They frolic and play in the waves,
In the ocean’s cool depths,
And they seem to enjoy each other’s company,
As they glide through the water.

Their grace and beauty is a sight to see,
And it’s easy to understand why,
People have been drawn to dolphins for centuries,
And why they remain so popular today.

Dolphin Facts for Kids

Dolphin Facts for Kids


The great thing about working with your child at home is that you can pick up on their interests.  Many children like dolphins and so I have decided to do this page on dolphin facts for kids and how that might be the start of a project.

I loved dolphins from an early age and enjoyed the children’s TV programme “Flipper”.  That ages me!  Flipper was a bottle-nosed dolphin who looked like this one.

Start with a video clip.

There are lots of video clips you could choose from.

Here is one from YouTube called ”Five Facts About Dolphins”:

Here are some of the facts that are mentioned. There are 43 species of dolphin, including 38 marine varieties and 5 river varieties.  Dolphins can swim at 34 miles an hour. Killer whales, which are a type of dolphin can be about 32 ft long. Dolphins are mammals not fish, and dolphins breathe through their blowholes whereas fish breathe through their gills.

You could just watch the video and then discuss it and see how many of the facts your child picked up on.  Or you could write out some questions first so that they’re listening out for the answers and writing them down.

Basic facts on a webpage

Here I’m going to give you some websites that should be fairly accessible to a lot of children and some questions to go with them.

You can copy and paste the questions into a Word document or something similar and then the child will be able to answer the questions from the information on the website.  It might be interesting to see how many questions are they can answer before looking at the website and use that to check there answers. Bear in mind that not all websites will give you the same information so you need to decide what you think is the most likely right answer, or whether you decide that nobody really knows the right answer.

Equally, you could start with one question and a suggested website and then your child could tell you what else they found out that was interesting. You could then follow up with further questions or perhaps give them a fact that you know and they can tell you if they already knew that from their reading.  They might like to give you a test. You can decide how much of an expert you can pretend to be.

This video is a bit longer than the last one. It is 5 minutes long. It recaps on quite a lot of the answers to the questions that we’ve got above and it gives some extra information.

Here’s another dolphin video – also about 5 minutes long.

This video is for older children and has some quizzes and lesson materials to go with it.

Ed-Ted lesson material –

Is your child ready for some quizzes?

Try these: – Just six questions but will you know all the answers? 10 questions

This one is harder but it marks itself as it goes along, so you get to learn at the same time.

More challenging questions, but again you get the answers as you go along so it is interesting to do.  The questions are randomised so you get some of the same questions and some new ones if you do it again.

(I couldn’t do all these and I couldn’t see the answers.)

At “All The Tests” you can do other quizzes or create your own.
