The Spawning of the Giant Clams
ฝัง
- เผยแพร่เมื่อ 25 ก.ค. 2018
- Giant clams are the second largest invertebrates, after the giant squid. Adults can weigh up to 500 kg. They gain nutrition from their symbiotic algae and from filter feeding.
Since they are tasty, immobile and live in shallow waters, they were over-harvested for many years, and their populations were in peril in the Philippines in the 1990s.
The Marine Science Institute of the University of the Philippines runs a giant clam breeding program to alleviate this situation.
Clams are injected with serotonin, which causes them to release sperm, and with a delay, eggs. The two types of gametes are then joined for fertilization, and the larvae are first grown in the hatchery of the UP Bolinao marine lab, and later resettled into the ocean.
Many thanks to the students of the UP Marine Science Institute for letting me film their clam conservation efforts. It's great to witness bright young people dedicating their talents to a good cause.

This is what Gary walked in on spongebob watching
Actually no
Its what spongebob and patrick raised as their child
i cant believe i just watched a clam come
Lol
Hahahahaha😂
😂😂😂😂
I cant believe i didn't know clams are just sex organs whos only purpose is to ejaculate and reproduce. It's the simple things i guess and here we are with our big ol brains.
It's marine biology. Take it as science!
0:43 *Even the giant clam is scared when it's being shot.*
no its aroused
Well yeah, they react to sudden movements and close.
I just watched a man make a clam nut..
Did you like it
Nope
Reproductive biology of a marine organism. Science!
Very science
Imagine getting your foot stuck in one while swimming
I saw a few when I went to the great barrier reef
It actually isn't strong enough to get a good grip on your foot.
Getting stuck in the tides is worse.
It wont let go!
They can't completely close their mantle. You wouldn't be stuck for good. A friend got his scuba pressure gage hose stuck in the corner of one, but that's much thinner than a foot of course.
Today I learned that for clams, you can make them splooge by injecting them with serotonin.
Yes, serotonin is quite universal, important in human brains too, of course.
@@pacificklaus8189 in humans though I would think the causal relationship is reversed 😂
Did I just watch onlyclams?
Underrated comment 😂😂😂
Damn clam been holding that back for years.
Really? A video of a hole between two lobes of flesh accompanied by that music?
Lol
Science, man. Biology includes reproductive biology as well.
what did reigarw comparisons just lead me to
RIGHT
😂😂😂 shame same
Yup
LOL I watched that video before looking it up. I was like how do they make so many??
Could you enlighten me what "reigarw" is? Thx!
Did you even call the clam the next day?
"Clams are injected with serotonin, which causes them to release sperm."
Damn, never thought I'd be jealous of a clam.
Give it a shot (this is not medical advice, hehe).
I don't even know how I ended up here...
I hope you enjoyed a few minutes of marine bio!
Imagine if u see these things move fast in the water like those small scallops
Giant claims mostly anchor themselves to the ground and are stationary for the majority of their lives. When they are young, they will float around as plankton before eventually dropping to the ground and starting its life.
These stay in one place, sadly. Would be exciting to see them jump.
Good take away from the video
How is this scene on TH-cam 1:02
Ewwwwww
wdym
How did they put a camera in the clam
Are you being serious? There is human genitalia on youtube and they know about it. Its all about what its for in the video.
@@cloker5363it was staying open??
Minor correction: the clams get up to 500 pounds, not kilograms, although that'd be cool
Yes, you are correct.
We just watched a clam have 500,000,000 kids
Exactly! But how many will survive to adulthood? This is the difference between k breeders, like humans who care for every offspring, and r breeders like clams.
1:50 when she says shes home alone
I have an exam tomorrow but here I am watching clams come... What am i doing with my life
Maybe your exams is about clam
Well, you could be watching worse things I suppose.
Or you could be the person whose job it is to climb up an elephants back door to help remove a blockage in their bowels!
That's a shitty job.
Wow, as a UPLB Wildlife Biology graduate, I never thought how awesome UP marine biology is 😁
They are doing a great job, yes.
What if they moved with a foot like other clams, that would be creepy, imagine a giant tongue thing sticking out of that giant clam.
When she says shes clamsexual
Great sharing sir have a great day
These clams really out here blowing their loads.
Hopefully we'll have more clams soon.
All Hail TH-cam recomendation
What's the name of the music used here? Can't seem to find it when searching the artist. Really nice tune.
This was from a now defunct creative common webpage, the artist was just a hobbyist who uploaded his music. Bummer that he is not around anymore.
@@pacificklaus8189 Ah okay, thanks for replying. I shall remember this tune as the Clam Jam.
this is what spongebob was looking at one his television
I miss her 😔
Interesting topic, but could the background soundtrack be any more insipid?
I will use calmer music in the future :)
This video should have a parental disclaimer😳
Haha, for bivalve parents.
I just heard a quote from (I think) Pliny the Elder that says giant clams were eaten in Rome. Is this true? Were they exterminated in the Mediterranean?
Interesting! This species is native to the tropics and subtropics, so probably they did not eat that. Likely a large Mediterranean species? It would have been too far to import these from the Red Sea without refrigeration.
@@pacificklaus8189 you could import them alive in boats right? Changing the water every now and then. It would have been very expensive but the Romans were not the humblest out there
@@da4127 true, the Romans had a taste for luxury, but I am not sure if they had trade relations with the tropical Indian Ocean?
Why did youtube recommend this video I wonder...
I hope it was informative in any case.
Do they produce giant pearls?!
Not that I know of. Plus, they are protected, so no legal chance to harvest the pearls.
Like any bivalve they have the ability to, whether anyone has ever tried to harvest it i don't know. It is their reaction to having some sort of debris which they can't dislodge from their bodies through normal means.
It takes thousand years to produce the pearls
@@gnomearmy6041 giant clams usually live for a 100 years maybe 300 in rare cases.
@@ANTSEMUT1 indeed
Man i wanted to take care of a giant clam
Hoping it's not some fetish after watching this video
I believe you can get smaller species for aquaria. The T. gigas in the video is protected in many countries.
Underwater cloud moment
Anyone from reigarw comparisons
I wanted to see 500,000 eggs but only saw weird clam sex
@@pedro55845 we got bamboozled
500 million fucking eggs
1:50 Violently shoots water
Where am I
Wait, clams have genitals ?!
Reproductive organs inside their mantle.
Pacificklaus do you mean penis
how else would they mate?
@@crabblab91 they dont have penises, they dont mate like we do. they release sperm into the water that fertilizes the female by being drawn to the bivalve by her siphons.

After the giant clam blew that huge load I expected it to light up a cigarette. 😀
We are working on genetically engineering them to be able to.
the music just adds
Thanks!
*_WHOAA...!! WHOLE FAMILY SEAFOOD DINNER..!!_* 😮😨😱
Yeah, they are in fact still poached, I haven't tried though.
@@pacificklaus8189 well... stay safe from high cholesterol. 😊🙏
What accent does this guy have?
Austria! A bit of it is left, plus the accents of a few places I lived.
amazing!
dahgan salamat!
why did i just watch a clam nut
Reproductive biology!
seaaa urchiin with urchiiin sea in clams ISLAND!!!!!!!!
I haven't watched any marine life vids in I don't know how long, so I have no idea why is this in my recommended.
I hope you enjoyed it nevertheless.
@@pacificklaus8189 I did. 👍 Thx for posting it.
Japanese seafood
@@tobiramasenju2204 Some people eat it. Protected in the Philippines, though!
Very science
Yes! Fascinating, isn't it?
@mandownbad
From facttez
Any one after fecttechz
Who is here after facttecz 👍👍
Omg
Nature is amazing, isn't it?
happy-ending...???....money-shot...???? L O Fuckin' L !!!!!!
🤘😁🐠
Ah yes, salt water
Yes, they grow in saltwater. shallow reefs, in the tropics. Need a lot of light.
clam sex LOL its having nocturnal emission
clams taste really delicious
These are legally protected however.
Gabe
They have 500 million babies at a time I heard I’ll
How i wanted to care a giant clam
@@pacificklaus8189 are they endangered?
Anyone here because of facttechz✋✋🙋♀️🙋♀️🙋♀️🙋♂️🙋♂️
After factechz's
LEAVE THEM IN THE WILD!!!!!
Let me explain ... all of these clams are from a breeding program, none are from the wild. The breeding program exists because they were almost extinct due to overfishing in the Philippines. The ones which are bred here end up on reefs to restock natural populations.
@@pacificklaus8189 Ok.

Seems a little...nonconsentual
