- A sponge might not look like much, but these simple animals with no brain or ability to move have lived on Earth for hundreds of millions of years. They can hunt prey and spawn, and Jonathan demonstrates how in this fascinating segment about the biology of sponges!

When people think of a sponge, they usually imagine something like this: a cleaning sponge for washing the dishes…or for washing the car. Cleaning sponges are synthetic these days, but they used to come from the ocean.
Back in the days before we had synthetic sponges for housework, cleaning sponges did come from the ocean. They were harvested by hard-hat divers walking along the ocean floor in heavy weighted boots with a rake-like tool to pluck the sponges off the bottom. It was a dangerous and difficult job.
Bagfuls of sponges were lifted to the boat above. Immediately, the crew set to work cleaning the sponges. Then they were hung to air dry. After days or weeks at sea, when the boat was full of sponges, they were taken to shore, where they were auctioned to the highest bidder. Finally they were trimmed, sorted and sold to the public.
Natural sponges are still harvested in nearly the same way today, but the synthetic sponge has spared the lives of countless ocean sponges!
While an ocean sponge looks something like a weird plant, it's actually an animal.
In fact, sponges are among the simplest multi-cellular animals on Earth. They live on the bottom of the ocean, attached to a surface and never moving because they can't walk or swim. Some are quite colorful, while others are drab. They also come in all shapes and sizes. There are tube sponges, vase sponges, barrel sponges, rope sponges, encrusting sponges and many other types. Sponges live from the frigid waters of the arctic and Antarctic, to the tropics. On many coral reefs, sponges dominate the sea floor and the drop off.
One of the most common sponges on coral reefs is the barrel sponge. Barrel sponges grow to epic proportions, getting larger than a person!
Although sponges can't walk or swim, they can feed. They do it by filtering tiny plankton from the water.
A sponge is covered with small pores, called ostia, which lead to a system of internal canals and eventually out to one or more larger holes, called oscula. Within the canals of the sponge, chambers are lined with specialized cells called choanocytes, or collar cells. The collar cells have a sticky, funnel shaped collar and a hairlike whip, called a flagellum. The collar cells serve two purposes. First, they beat their flagella back and forth like fans to move water through the sponge. The water brings in nutrients and oxygen, while it carries out waste and carbon dioxide. Second, the sticky collars of the collar cells pick up tiny bits of planktonic food brought in with the water.
Sponges are very effective filter feeders, since they are able to capture and eat particles as small as bacteria as well as much larger particles. They might not look like they are doing much, but a simple demonstration shows how effectively sponges can pump water.
On a reef in the Caribbean, I make a dive with a syringe filled with a non-toxic dye called fluorescein. By squirting it around the base of some sponges, we can observe how the water is moving by watching what the dye does.
Within only seconds, the dye is pumped through the sponges along with the water. As you can see, a sponge is a pretty good water pump, and also a good strainer. Any plankton that goes in with the water, won't come back out through the osculum.
Tube sponges are even more spectacular to observe. They pump the dye so furiously that they look like a collection of miniature smoke stacks!
Since sponges can't get together to reproduce, they spawn in a way similar to coral. The sperm is released into the water column by the male sponge and finds its way to the female sponges, where fertilization occurs internally. Eventually, the planktonic larvae are released from the female sponge and float around in the water column as plankton for only a few days. They then settle down and start growing.

Sponges are animals, Venus flytraps are plants, mushrooms are even something totally separately,... nature is so confusingly fascinating!
Mushrooms are fungus
@FTT_Flasher _YT sry but Mushrooms belong to Basidiomycetes Class of Fungi.
@FTT_Flasher _YT lol what? Sea songes are no where close to mushroom. Maybe they have a common name relating to Mushrooms but that would be a misnomer. For eg. Silver Fish is not a Fish but arthopod.
King of herb-Ganoderma lucidem the mushroom
I know sea sponges are animals, like corals, even my science teacher doesn't know that corals are animals.
When I was a child I dreamed of having a job that involved exploring the sea. Now I'm an adult and dream of a day when student debt and bills don't haunt me.
lol
:´-( very beautyfull !!!!
souperman72 hey as far as we know we only get one shot at life. Follow your dreams man
souperman72 same
Aw you still have a chance!
6:27 does this remind anyone of when SpongeBob had bad breath?
I’m ugly and I’m proud!
Yeshhhhh
Once there was an ugly barnacle he was so ugly that everyone died. The end.
Same
1:42 "Immediately the crew sets to cleaning the sponges"
- 8 seconds of a guy throwing a sponge on the floor. lol
Josh Bodhi'Sattva I actually felt bad in that part becuse of sponge bob. But it is hilarious!
"8 seconds of a guy throwing a sponge on the floor."
That's how they knock all the sand and stuff out of the sponge's cavities, so yeah, that's part of cleaning it; but it did look kind of funny, now that I think about it.
It looked like he was really bored and was contemplating life
Magnificent piece of work, great effort to find the old footage to include, you deserve millions of thumbs up. The Turtle was so cute using the "hands" to eat. Another Masterpiece.
thats how i clean a normal sponge. just smack it around
You just made biology so much fun to study ❤️
I'm so glad we make sponges artificially now, after seeing how they were being treated.
Bro humans are eating plants. we have to do something for plants .
But they can feel nothing.. they are not sentients but did you know that animals you eat are treated worse than this..you should be a vegan then
@@rutikghuguskar bro.. humans are eating animals we have to do soemthing for animals..
@@saveearth7907 PLANTS LIVES MATTERS
@@brobroman425 yeah . And animals doesn't.
I’m not sure if sponges feel anything, but I still felt sad when I saw all those sponges die to become scrubbing utensils..
Ha.
Ha.
@@i-am-nothing-yet-i-am-ever5695 they lack nervous system but they respond by pinacocyte, a special type of sensory cells which are specialized to difference between consciousness and unconsciousness.
They do feel pain but sponges have high power of regeneration.
@@shrutisinha7007 like plants?
@@toni929ann kinda but they are put in kingdom animalia because they lack chlorophyll and catch their own food and also they are hermaphrodite animals i.e, they release both sperms and eggs. They also known as blind branch of evolution cause not a single animals shows relation with sponges but they resembles much with colony of bacteria.
the pumping dye moments were so amazing, looked like almost like greatly done CGI, magical.
and I thought this was going to be a bit dull to watch, that looked fantastic.
+Jayme Capurso Thanks for watching!! Science is awesome!
we're did the dye go
Johnathan
+Michael Grant it probably dissipated into the water and became so diluted you wouldn't see it.
0mn0m8w31rdc4ndy ok😸
+Jayme Capurso it was really fantasic
So, not only is it one of the most beautiful channels on the ocean, it's also one of the most informative. Thank you Jonathan! You rock!
You have inspired me to be a marine biologist when I grow up

But we might not have a sea when we grow up
Keep up your labour and w
One day you will
Yay! New episode! I find it very enjoyable and relaxing to watch Blue World in the evening when I am winding down for the night. Glad to see more, I was disappointed when I got to the end of the vids list a while ago. Love this show!
Never fear! Many more coming!!
We get it squarepants, you vape

thank you for having these up for free in full. these are fantastic! i wish it showed on my local tv channels. love it
Hey I am from India preparing for my medical entrance (NEET) and this gave me what information I was searching about sponges in a very interesting way. Thankyou and
Keep it up......
Your videos are so fun, interesting, and factual. Thank you for all of the wonderful underwater footage! I wish I was a mermaid. haha :)
Exactly exactly and exactly i love his videos are the best!!!
an interesting wish
I like these kind of beings, they seem so pieceful and quiet, i relax watching them.
He just casually and not-at-all-ominously ended it with: "These creatures will outlive every single one of you :D"
the history of sponges! thanks Jonathan! 💕
does dis mean spongebob eats planktons?
+jayjay duque Yep!
dis makes my childhood worsen and makes adulthood and brain more smarter
Hey sion
sup
and sea stars also eats Sponges soo...
Aw you're awesome! I love sponges. They were my favourite animal when I was little :D
Spongebob actually belongs in the sea! :D
Watching this video is very educational about the sponges. Love how Jonathan as narrator is very enthusiastic which adds more excitement in watching. It is soothing and it brings calmness.
Glad you enjoyed it!
The sponges are mesmerizing!!! :) beautiful :)
This is one of the best documentaries I've seen, I re-watch it every year or so for those beautiful shots.
Wow!! This is an interesting video!! Thanks😊
This guy's got the right amount of energy for sponges. Thanks man
I didn't know sponges could be so..... Interesting.,
Your underwater photography is so awesome...This video was fascinating and I learned a lot!
I want to Thank you for expressing your loving grace for those sponges that deserves our loving attendance.
Each reef system had a chance to feel important with your caring examples.
Thank you for giving the sensible possiblity of external influence charm from around thier sensitive timings.
Never felt so excited about sponges before!
this made me want to watch Spongebob
me too!
Imagine spongebob being harvested like that...OH THE HUMANITY!
Lol
Same!
This video is outstanding! Thank you so much! We are studying the classes of invertebrates and this was perfect! : )
Amazing shoot and background music and voice is awesome
Mind fresh.......is mind fresha
I love this show. I only started watching this and I have learnt so much, Jonathan bird is amazing
The dye part is so cool!
That dye is an amazing colour.
When read from the textbook it just felt nothing...After watching this video i just loved and this so fascinating and magical. Thanks a lot for this informative and well presented video!!!!!
Sometimes a picture is worth a thousands words. And sometimes a video is even better.
The sponges are so simplistically fascinating!
This footage is amazing
That got dark towards the end there lmao "Humans can't hope to outlive the mighty and prolific sea sponge!0
Very beautiful.......by sitting at home we came to know so much about sponges
When I was a kid my dad told me that this is where sponges come from, I named all my sponges.
4:25 That huge Barrel Sponge is probably a lot older than any of us!
According to wiki, "the largest (giant barrel) sponges on Conch Reef, about the size of an oil barrel, were estimated to be about 130 years old. The largest individual for which a photograph was available (now dead) was estimated to be 2300 years old."
sponges were probably among the very first animals to evolve. You can see they're somewhat similar to fungi, but they are technically animals.
thx for stating info we already know
They are like a step-ahead unghi on evolutionary line.
they are "technically animals" because they technically are their own type of organism. They are plants or animals OR fungi although we try to act like we can classify it as such because it "fits mostly with" this or that.
@@thecraftinfluffy149 u are from which country????
@@Mohit-ou4yb I am from Jaipur
I cannot believe the wealth of information that these videos produce. I have sent them to all my grandchildren. I just love love them.
Glad to hear it!!!
Sir u do narration better than anyone in this field... amazing... I must say u definitely live a colorful, exciting, adventurous and peaceful life..god bless u so that through ur adventures we can also enjoy and experience beautiful ocean life...all the best
Hello! I just wanted to say that I really enjoyed your video! I’ve had a very weird obsession with sponges since I started learning about them in my marine biology class so thank you for making a video about them! I just wanted to point out that you were saying male and female sponges in your video but sponges carry both sperm and eggs, making them hermaphroditic reproducers. Thanks again for the video!
Yes, you are right, but at the time they spawn, a sponge can only perform one role. So one sponge cannot produce sperm and eggs at the same time. Hence, they perform a male role or a female role. The next time they spawn, they can change roles.
@@BlueWorldTV like hydra , right?
Wow. I really didn't expect to like this, but this was an amazing vid. Thanks Johnathan!
really cool experiment in the video, didn't realise they pumped water so fast!!
They look magicalll!!!
What!? So you mean to tell me that sponges don't actually live in pineapples, under the sea?
They do if we believe hard enough
+Griffer Doodle xD
If you have, imagination! Then yes, they do.
you talking about SpongeBob SquarePants 😅

Omg, thank you for the like
Amazing, I love this episode! May I suggest for the next episode : Sea snails!
Heck, yes! They are interesting. There are actually many big and carnivorous ones, sea snails are so much more interesting than the boring land snails we're used to seeing.
first Spongebob then Gary?! EPIC
CakeyBakey_05 lol
@@iwilleatyourmother U MUST BE AN AMAZING PERSON!!! XD
Interesting video. I’ve got a lot of sponges in my tank and wanted to know more. Some grow fast. Some gore really slow. Interesting animals though. They give a glimmer of beauty to the tank. Glad we have synthetic ones now. Sponges are beautiful to see when diving.
when that smoke out came from that demosponge, plus that background music, it looked as if a spirit was comming out of a pot
Sponges are so interesting :) great vid
The thing with the dye is so freaking cool. Looks almost magical
What an awesome video!!!!! Great Job Jonathan!!!!!!
Thanks!!
Thank you really!!! Provided much more insight about Porifera than my books ever had!!!!!

Love from Taiwan
This video is awesome, amazing, and wonderful. I really want to show my sincere gratitude for you. Thanks for adding the subtitles, really helpful. I think a lot people in Asia being afraid of getting close to sea is because we don't know sea. Ignorance causes fear, I guess. So your video is super good and important. Thanks again!
This is so awesome. I never knew that back than sponges were harvested from the waters. This is such cool info. Thank you
such a beautiful video entertaining , knowledgeable,educational,intresting!!!kepp it up excellent work
Thank you so much 😀
It amaze me how diverse life is in this planet alone...An alien world out there with life will be mind blowing.
Now sponge doesn't even sound like a word.
Bro, I was literally about to comment that , then I saw your comment x)
Thank you for the instrumental surf rock in the background, what a nice touch!
I would laugh if you found a sponge that loitered near a sunken pineapple!
What about if it was also next to a crab and a pink seastar
yo bro

Very surf rock
This video lacks pineapples.
Lol
Rocks and Starfishes too...
LOL
lol
This is beautiful 😍 I used to have a teaching demo about sponge and protozoans. I wish I had this video back then.
Wow sponges are explained so wonderfully in this video. When I read it from my textbook, I just couldn't understand this. Now I understand everything so beautifully. Thanks a lot Sir!
Love from India.
this is like magic
Its nice to see where Sponge Bob came from!
I like the variety of sponges and that trick you did with the dye!
@tee bee The character Sponge bob from Nickelodeon.
I was joking about him while watching a video about real sponges.
@tee bee oh!
Ok!
Well there are plenty of videos of him out now!
Coolest demonstration ever. I never knew most of what you said, and the dye demo was so interesting! As usual, thumb's up!
That sponge harvesting video was pretty cool.
Amazing species and amazing footage. I actually find sponges very exciting now :)
It's also nice to know where they used to get cleaning sponges from. Great video!
Glad you enjoyed it!
The music of sponge spread the coloration so amazing
Hi Zane. I am "Zimmy" the composer. So glad you like my music! It was fun writing it! Keep watching Blue World!
Ich sehe den fröhlichen und lustigen Jonathan sehr gerne - fit und gesund 👍🍀🥳
Magical! Thanks Jonathan!
Your intro is the best one I've ever seen
This is a true story that happens to me all the time:
My Friends: Hey dude, whats your favorite thing to watch on youtube?
Me: It's this guy name Jonathan Bird-
My Friends: Who's that?
Me: He explains the biology on animals and dives with them. I recommend you watch him, hes really funny.
My Friends: WOW YOUR SUCH A NERD!
True story.
JJ Burg A super cool knowledgable ocean nerd!!! Just remember that in life, nerds are the ones that go the furthest and make the most difference in the world!
I need to see my friends reactions after I tell them that im watching sponge porn right now.
darren newell LOL
Jason Burg i can relate to that,my freinds even call me gay just because i watch this stuff
Awesome Eliam hahahah same o get wacked like a fucing dog by my mom for watching this
Such an amazing demonstration with fluorescin
People support no sense things please support these types of channels. This type of people deserve your support and love you sir 🙌♥️
Great video. Short and very instructive.
I used this to supplement my lesson in my Taxonomy unit. I love how you explain things and how you add words and diagrams to the screen. Thank you so much! That's so hard to find! You just need some for marine worms and jellyfish videos.
Great educational footage showing importance of spongesin entire ecosystem. They work as natural filters cleanig water. There are fascinating fresh water species too.
This video takes me back, I loved watching his videos
Beautiful shots in intro - swimming among all kinds of fish including astronauts (0:33)
wow so awesom great video
This was amazingly fascinating, Thank you.
The method you use is absolutely amazing and appreciating
Well that explains why spongebob sometimes likes plankton and be nice to him
He's nice to almost everyone.
Fun Fact: Sponges are one of the oldest living species on Earth.
Edit: Commented before watching the video lol
Two year old comment and no comment on it so I just thought I would add this
I have never seen a barrell sponge that large before..next to the human it's enormous...thanks so much i learned a lot..love educational videos...the dye was spectacular
Glad you enjoyed it
RIP spongebob 😂 nice vid!
That would be spectacular if you saw sponge tube can be pumped up with dye and if it’s super cool that means it will be very first with the light dye.
Loved it!
amazing exploring under water like a heaven very beautiful.
What an amazing sponges!.. awesome!
