Hydra Eating Daphnia

[bodybuildingispain]

Your a pussy

[hailmail321]

0:43 "It was like...spazzing out." ROFLMAO!!!!!!! This is why American public schools don't work...

[InfiniteRedPill]

@hailmail321 I don't understand your knowledge. That sentence "It was like spazzing out" was spoke by one person. It does not reflect the American education system at all.

@jackhorncool

Triops don't like hydras. They have fragile gills on their feet, the stinging of hydra would hurt them a lot or even kill them if they are not *at least* 2cm long. If there are a lot of hydras in a fish tank, even the fish can become uncomfortable. They don't die, they are way too big, but they are annoyed. Only very few animals eat hydra. A few snails and *very* few fish.

Triops are also no "kick ass predators" though they are more or less predatory, yes.

[sErgEantaEgis12]

OM NOM NOM!

[41stgaming]

@jackhorncool: me vs. ur triops, I kick their... ya they dont rly have asses either :P

[weiner66]

so I am to suppose this hydra will use a simple straw that dehydrates away the essential juices of life, leaving one more daphnia an empty husk whistling in the wind, it's hopes and dreams turned to an ingredient in someone's soup?

[headcrab4]

I wish that we look at cool things in microscopes in my biology class. all we got to do was use crappy ass microscopes where you can actually see the things with your bare eye. large, lifeless, particles.

[superladyscorpio]

this video helps for my assignment..coz i haven't examine a hydra coz im absent at that day:(..

thanks btw..

[YupiM55]

Кто кого съел? ))

[AmazzTasticFillms]

Just to clarify, I was STUPID when I put that previous comment and I'm SMART now. So ignore it. :)

[smokeyflea]

Aahh... the jibber jabber of young students.... They don't know what they're missing!

[davidestar93]

You find this during a biology lesson?

Cool :)

[roar9998]

@AmazzTasticFillms Sorry, but there are already SIX kingdoms: Bacteria, Archaea, Protista, Plantae, Animalia and Fungi.

Solomon E., et. al. (2008). Biology. 8th Edition. Cole, USA: Thompson Brookies.

[AmazzTasticFillms]

To clarify:

There are four kingdoms of life: Animalia: Daphnia Plantae: not in this video Protista: Hydra Monara: not in this video Fungi: not in this video

Bacteria are priokaryotic cells in the kingdom of MONERA. Hydra are eukaryotic cell creature things in the kingdom of Protista. (protists).

[gamehero77]

@AmazzTasticFillms Also, Hydra's are part of the kingdom Animalia, due to the fact that they are part of the Cnidaria.

[matttkp]

we observed this today in bio , and in 1 case the daphnia actually ate the hydra , and then died from being stung form the inside.

[wifengz]

that stuff kills the daphnia? cool!

[tonyisag]

amazing video. too bad the students had no idea what has happening

[tonyisag]

*was happening

[Julianos99]

it's 1:02 AM, i have a ridiculous amount of homework left, and i'm watching a video about hydra. shoot me

[luckymumble]

lol i do that too

[The95thRifles]

@Julianos99 you shit nerd

[aussieriemen]

@The95thRifles its a microbiology video. You have to be some what of a nerd to watch this Captain cool 

[jjmeowmeow]

haha i know kids studying Hydra and Daphnia in 6th grade! They did the lab TODAY

[littlestein]

We did this last year.

The daphnia had like 7 babies.

The babies were birthed while it was being eaten. Then they were eaten too.

[XSomebodyToldMeX]

We did this in the lab today! It was awesome :D But our hydra was more lively, it was shaking the daphnia around :P

[123krazykousins]

Hunter COLLEGE HIGH SCHOOL? Does those words in caps make sense when put together?

[casacorrer]

which is daphnia and hydra?

[secularmike]

daphnia = pink, hydra = tentacles

[tootiekorps]

Pit the beings, enjoy the kill, celebrate nutrition, revere in cruelty. survive, then expand.

[callofdutyguy247]

we did this today and their were babys inside the daphina and they were trying to get out

[KillerKikyo5]

looks like an ant not a hydra....lol..

[zoejoinnowrulez]

my class watched this!!! and all of a sudden @ the beguinning of the video a girls voice showed up and everyone was like it sounds just like me and i was crackin up!!!

[telswood]

daphnia got owned.

[41htdex]

hahahahahaha

[Redkiller66]

Random

[puFFkinQT]

GAH!

[gir12356]

did u do this i a class?

[iiiicooldaysiiii]

omg...i just saw this video !!

poor my liltle daphnia ;(

[torpedo192]

The hydra is immortal

[MetallicaSucksNow]

Hell yeah, it never fucking dies!!!

[FyerEgg]

"Hydra! I choose you!" (Pokemon style)

[cusanusnicolas]

Nazis!

[MetallicaSucksNow]

ye right!

14/88

[jaylew1987]

poor daphni being eaten alive... nasty

[ZurDruid]

jaaaaaaaaa

[DiluteMeDown]

im not sure a hydra would be capable of completely swallowing a daphnia...

[scosnyde]

Great Cnidaria rex!  (not sure what rex stands for....but it sounds nerdy enough)

[GHOSTBGA]

ahahaha, someone said "the hydra is really big". It's obviously magnified.

[MicrobeGuy]

The Hydra didn't actually swallow it in the video.

[VinkkieZ]

Your class so noisy

[LoveMyQuarterHorse]

Hydra is an example of phylum cnidaria, which includes the jellyfish. They both have tentacles lined with stinging cells called cnidocytes. The cells contain a harpoon-like barb, connected to a poison sac, that shoots out on contact and stings the victim. It is one of the fastest biomechanical actions in nature.

This hydra has caught a daphnia much larger than itself but it's going to have a difficult time digesting it! Nevertheless, eventually it probably will.

See? Biology is cool!

[pizzaoverlord12345]

@LoveMyQuarterHorse i thought the harpoon like barbs are called polyps :P is this right????

[KlarLogik]

@pizzaoverlord12345 not sure if your question has been answered already but it doesn't seem so. Polyp is the body form of the hydra, like the body form of a jellyfish is called a medusa.

[breakfast37]

hahaha "It was like spazzing out and it like died I think"

and "Tell the jelly fish to eat it"

.

[starryang3l]

i am so sorry i haven't learn that yet, but which one is eating which? the big on is eating the small thin one rite?

[VoteNixon2008]

Daphina doesn't have a heart it has one chamber that contracts. What you saw was it's respiration bladder contacting

[nemesisnick66]

i hated those big line things that was on the lense

[jnsjnsjns]

omg

[savvyone]

POKE IT

[nemesisnick66]

lol

[maarakailet1]

Cool! Never seen that before.

[SabahMi]

I don't think hydras have a heart hun

[SabahMi]

oops, I didn't realize you were talking about the daphnia...which does have a heart.

[Mildewpants]

Yeah, daphnia do have a heart, but that 'heart' they were talking about in the video was actually a baby daphnia inside the larger daphnia.

[narutoandhinatafan]

It looks like it has it's eyes clsoed as if it's sleeping :p (Hydra)

[aldsmooth]

How cruel!!!

[popr0x37]

not really, its a lab experiment all biology studens do, i just did it today

[Presidentjh]

nature's cruel.

[jerms88]

That's life.

[BlueDragonOfAlex]

Whats a hydra?!!

[JGaudet06]

Hydra is an immature jelly fish and the daphnia is a minute water flea, the hydra is positioned ontop of the flea and sucking its insides out through a tube

[Mildewpants]

Hydra aren't jellyfish, they are simply related in that they are both from the same phylum.

Saying hydra are jelly fish is like saying that humans are lizards because we are both in the phylum chordata : ).

[LoveMyQuarterHorse]

Heh.  Good analogy. :-)

[UnSeminarChildren]

Hydra are in the same phylum as jellyfish (cnidaria), but they're not immature jellyfish.

[Kickasss119]

yah, they looks similar, its called a polyp for a jellyfish

[mishyyycakes]

wrongg, hyrda are in the phylum hydrozoa.

[yehoshua2123]

xactly

[Dzakovich000]

No, they are in the phylum cnidaria, the CLASS is hydrozoa...

[ShadowclawFC]

Exactly. They are in the Class Hydrozoa, while Jellyfishes are Class Scyphozoa. Also, as said, Hydra are not immature. They do not have a medusa stage at all, only a polyp stage.

[WrathOfDemons]

@JGaudet06 dat means its gonna turn in to a jellyfish later??

[siperdellyeer]

@JGaudet06 they do more like squids :P

[MaskguyEvan]

Methinks the fimer and their friends are about as intelligent as a rock.

[briankid]

Congratulations to you.

[Altairw]

It is not the heart, its a baby daphnia moving its "tail" inside the (dead) mother. Cool video anyway

[jtlege]

I think you're right, (my only qualifications for daphnia heartrate are the other youtube vids) I definitely dig your highpothEsis. I really liked the soundtrack too, the young lady seemed ickified but reasonable, observant,and insightful; and the 'dude' well hey its always cool to see critters eat other critters right?

[Altairw]

yep, the heart is in an higher position, the thing that's moving inside the back is were daphnias has the reproductive system.

[Vadimex]

There is no baby or mother of any protist. They use cell division, so there really isnt a parent or a "baby".

[Altairw]

incorrect, waterfleas are crustacean not bacteria. search for the video "Water flea's birth scene" to see a daphnia giving birth

[Vadimex]

Ah, sorry. Just seems unlikely, you know?

[UnSeminarChildren]

lol, but bacteria are not protists either..

[muhajidin]

you can see this with light microscope..??

[Kantermejo]

So how would you explain the birth of the daphnia?

[musicianhayd]

is that little thing in the middle it eating? i'm confused...

[Mikiyikiy]

wow

[runescapecat454]

why do they eat each other raandomly. Like amebas and paramecium

[XPISigma]

They don't know what the heck they are doing. They are just like "whatever" all of the time.

[ramenluver77]

ooo it scruched up at like 1:02...

i see da heart...ITS ALIVEE

dum dum DUM!!!

[yukikazepilot1]

lol

[lotusfae]

I just watched this happen in lab this morning. It was adorable. Nice video... love the commentary.  "Tell the jellyfish to eat it!" Haha... cute.
