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.

  1. Lovely post!! Very informative! Your pictures are so beautiful! We see dolphins near our shores and in our bays often! Also had several chase our cruise ship once. It’s wonderful to watch them play and enjoy life as they should. Free and not contained! Been awhile since I’ve been near the bays, I need to go again soon to see them. Thank you for sharing your post!

    1. Hi Nikki,

      Wow, I would love to live somewhere where you can see dolphins swimming in the wild!

      I think it must be time to book another cruise and hope I am lucky enough to see some!

      All the best,


  2. Wow, what a fascinating poem story about dolphins. I see dolphins but never knew  much about them until today. Such a lovely creature but honestly I am scared to touch them. I use to see dolphins as dangerous or can harm and bite but on the contrary they are lovely creatures always seeking attention and loves it when they get attention from humans. Dolphins should be left to be free instead of being held in captivity.

  3. Thank you very much for a very interesting article about dolphins. You uncovered such interesting facts that I never knew about. In general, these are very amazing mammals. I have never been to a dolphinarium. I once wanted to visit but could not. It was closed. Have you been to the dolphinarium?

    1. Hi Rufat,

      I have never been to a dolphinarium either. I both would like to go, but also believe that these creatures should be left to roam the earth freely.

  4. This post is amazing in regards to multiple thing a kid can learn to be a better person from dolphins (real name: Delphinus Delphis).

    They are so much fun to fall in love with them for kids and as well as adults. They are found around the world from hot to cold climate regions. Some of them live in rivers.

    We can learn a lot from these lovely, cute and graceful animals.

    They swim, jump and play happily. They are stress relievers for us  I am not sure how you find a sad dolphin! 

    Dolphins stick together in groups. They take care of each other. They search and rescue like an intelligent man.

    They are naturally happy animals. It’s awesome dolphins have unique breathing systems and brain connection to sleep and stay awake at the same time. They can rest and nap well.

    It’s unfortunate that so many dolphins are in captive for human enjoyment. 

    Do  you like short-beaked or long-beaked ones! I love them all.

    1. Hi Anusuya,

      If I had to choose, I would probably go for the short-beaked dolphins as they are the ones I was first aware of – as a child, watching programs like Flipper!

      However, it is fascinating to discover different types of dolphins – and they are all wonderful!

      All the best,


  5. Thank you for such an informative post on such a majestic creature like a dolphin. I knew that dolphins are among the smartest creatures on earth and it is very sad that many of them are kept captive to perform tricks for us, they must be left free in the ocean in their natural habitat. I never knew that they keep one eye open while sleeping.

    1. Wonderful! I love your “PlayFullness” with language.

      That inspired me

      I took your last line and fed it into my AI:

      The Protectors of Infinite Oceans
      We come in all shapes and sizes
      standing vigilant against all odds
      our strength lies in our unity
      we are the protectors of the infinite ocean
      from the mountains to the valleys
      we stand united to protect her shores
      no obstacle can keep us from our duty
      for we are the protectors of the infinite ocean
