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.

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
Spongebob actually belongs in the sea! :D
Ich sehe den fröhlichen und lustigen Jonathan sehr gerne - fit und gesund 👍🍀🥳
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

@@iwilleatyourmother U MUST BE AN AMAZING PERSON!!! XD
This footage is amazing
Here i am the one i like the most.i am indonesian and i see this video until it runs out,because it is very educational and very useful.and the cooler there are indonesian subtitles rarely are there rarely like this.TERIMA KASIH(thank you).😊😊😊😊😊😊.....
You can thank this nice young lady who did the Indonesian translation!

Wow. I really didn't expect to like this, but this was an amazing vid. Thanks Johnathan!
I searched for Ray Optics and got Phylum Porifera revised.
God's creation is beautiful ❤️. Thanks Sir for the video.
Imagine being a sponge diver back then and being the one to find out the sponge you just touched was venomous or poisonous
The only living bird that live to tell the tales...legend says the bird still diving to this day
It's funny because in spongebob squarepants plankton the character has interacted with spongebob yet he is not scared of him
So satisfying to watch
they would be perfect for aquariums and ponds to have as a natural living filter!
The barrel sponge looks like the steam coming out of a steam locomotive’s funnel
Longer than people? Shoot, there are many who have outlived eras!
I love the sea and I would love to be a scuba diver to do more with the sea
The biology teacher showed your clip. ❤️❤️👌🏻
Good to hear!
Gods creation is amazing 😍
Wow sponge pop 😂😂
Its so cool!
6:00 7:25 WOW. It's like a magic 🧙♀️
Who Noticed Thet The Line Of Sponges Looked Like Onix The Rock Type Pokemon???? xD
Kawaii_CloudMaker_ 67 what time?
Nvm
1 year, but why did you type every word in caps
Thanks
I don't like the part where they gathered up the sponge from the ocean, thus killing it... I damn sure do wish that we have a sponge fishery. That way, harvesting the sponge is sustainable and help to leave the ocean sponge alone. :(
+eitkoml Regardless of their lack of a nervous system, they are important to the ocean as trees are important to land. Don't know why I bother, nobody cares about this world anymore. This planet is gonna turn into the movie WALL-E
+Colten they are not even close to being endangered anyways.
No brain = No pain
Brock Cherry I'm thinking coral. Completely different. My bad.
asdfghjkl still their animals and they wanna live even if they don't have a brain they can feel to live
AHHHHHH THE SPONGE SNAKE HAHAHAHAHAHA
nice sponge!
Good video brother 👍👍
Thanks 👍
Who is watching this episode in oct.2018 hit like button, for Jonathon bird's blue world
Admit it man....
WHEN WE WERE TAUGHT ABOUT SPONGES THE FIRST THING THAT CAME IN OUR MIND WAS ABOUT CLEANING SPONGES
Do a vid on snake heads(snake head fish)
you forgot to mention the bob sponges
i would go in the barrel sponge and take a selfie
hmmm...wont it kill u?
Jajajajaja eso luce como un "no le toques el "organo" a David Jones" XDDDD
The ocean is cool
Sponge bob has some cool relatives
We ar at the Pacific coast to film a blue world fish filming sponges
Ooooooh! WHO LIVES IN A PINEAPPLE INDER THE SEA ?!
1:00 looks like he's gonna murder spongebob.
The word “sponges” has now lost its meaning to me
Subhan'Allah!!!!
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.
Who is here after studying Kingdom Animalia
LOL. Marine biology 101!
Real me
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
We get it squarepants, you vape

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
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.
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.
You just made biology so much fun to study ❤️
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...
*Spongebob is shaking*
Omg, thank you for the like
This video lacks pineapples.
Lol
Rocks and Starfishes too...
LOL
lol
That's actually pretty magical. Kinda hilarious how cool and complex a simple sponge is.
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 😅
Lucy Smith supper
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
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
this made me want to watch Spongebob
me too!
Imagine spongebob being harvested like that...OH THE HUMANITY!
Lol
Same!
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

Aw you're awesome! I love sponges. They were my favourite animal when I was little :D
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......
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
the pumping dye moments were so amazing, looked like almost like greatly done CGI, magical.
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
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
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!!
Now sponge doesn't even sound like a word.
Bro, I was literally about to comment that , then I saw your comment x)
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?
I was expecting alot of Spongebob comments and I am not dissapointed.
That got dark towards the end there lmao "Humans can't hope to outlive the mighty and prolific sea sponge!0
SpongeBob comments aside was anyone else digging that guitar soundtrack during the sponge processing?
Very surf rock
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!
Anyone after geetan sir s class
😂😂 sir ne name change kar diye kya
It looks like cyclops from the spongebob movie
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."
thank you for having these up for free in full. these are fantastic! i wish it showed on my local tv channels. love it
0/10 no pineapples or pink starfish.
No but this was actually pretty interesting.
Patrick?
SubhanAllah 🕋❤
when that smoke out came from that demosponge, plus that background music, it looked as if a spirit was comming out of a pot
When I was a kid my dad told me that this is where sponges come from, I named all my sponges.
Amazing shoot and background music and voice is awesome
Mind fresh.......is mind fresha
I like these kind of beings, they seem so pieceful and quiet, i relax watching them.
Ohhh , who lives in a pineapple under the sea ? SPONGEBOB SQUARPANTS !!!!
Incredibat I CAN'T HEAR YOUUUU
Whos yellow and square and looks like a fish? SPONGE BOB SQUARE PANTS whos nauthical nonsence is something you wish? SPONGE BOB SQUARE PANTS. (Based of my memory)
ABSORBANT AND YELLOW AND POROUS IS HE?
This video is outstanding! Thank you so much! We are studying the classes of invertebrates and this was perfect! : )
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.
I didn't know sponges could be so..... Interesting.,
He just casually and not-at-all-ominously ended it with: "These creatures will outlive every single one of you :D"
Wow!! This is an interesting video!! Thanks😊
Your underwater photography is so awesome...This video was fascinating and I learned a lot!
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.
Dear Jonathan Bird'
I really love your videos that one day I wanna be like you.
I won't do it yet until I get my fear over sharks.
Your nine year old friend, Francess
KCF cousins Thanks Frances!!
BlueWorldTV I love Jonathan Bird! I loved the one with the baby sea turtles!
KCF cousins Why are you scared of sharks? I mean, OK, they are the ocean's apex predators, but most don't mean or don't want to attack humans.
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!
Do sponges have an important role for our water and stuff? Cause I always wondered.
+Jackie Gonzalez Yes, without sponges we would have 3 feet more water in the ocean.
+Jackie Gonzalez they actually control the amount of oxygen on the oceans
idk watch the video or watch a video on youtube about it you spam bot
I love this show. I only started watching this and I have learnt so much, Jonathan bird is amazing
I can see now why they decided that the cyclops should be a diver in the Spongebob movie, lol.
such a beautiful video entertaining , knowledgeable,educational,intresting!!!kepp it up excellent work
Thank you so much 😀
your video is to cool!!!! my mum loves the barrel sponge cause it`s very strange and huge !!!!!!! make one about cnidarians
just think, if spongebob didn't exist than we sponges would be a lot less popular
How do you know a sponge doesn't have a personality?So many beings in the universe doesn't exist in the way that some people understood.Even a little stone has its unique frequency.
