Daphnia Heart Beat

[question819]

that is wrong,my teacher is a scientist.the heart is near the head

[nightofthemars]

cant even find the heart...

[IsaacSnowfield]

i wonder if its dead.. struggling or something

ive seen one under microscope a couple of weeks before and it keeps moving as if its on fire...

[jj987987987]

[jessikarheartsyou]

AWWW \

[IndigoGrizzly]

@scotlandloose sorry

[IndigoGrizzly]

@scotlandloose Okay, so guess what I did in Biology Lab today? haha umm we counted the heart beats of the Daphnia....sorry :/ we can be friends now. But only if you improve your spelling skills :) bwahahah

[IndigoGrizzly]

its spelled h-e-a-r-t, not "h-a-r-t"

[IndigoGrizzly]

@scotlandloose Okay youre fricken dumb because Daphnias dont have a heart dumb ass quit arguing with me OMGosh!!!!!!!!!!!!!!!

[Thewaterofthepool]

What is a daphnia, a hydra, or a volvox?! O.e HOW DID I END UP HERE?

[linkwarior5]

[IndigoGrizzly]

Hearts on the back

[Zaclarke123]

think of that inside your ear

[lolley1100]

[gangstaz001]

where is the heart??

[Aquaticopia]

WOW, what magnification is that? Also, do you know what species? I have what I think is Daphnia (pulex?) but I may be completely wrong...you are clearly the bio-student! Any help with identification would be much appreciated, sorry for the poor quality (compared to yours).

Why does not she jump ?

[felixthemaster1]

@382982408

because "she" is in a glass slive with very little water. she is stuck and cant move at all.

[382982408]

@felixthemaster1 Oh,I see~

[TheGanstaben]

@KillerKikyo5

Yeah, sucks to be it... big time.

[felixthemaster1]

@KillerKikyo5

ermmmmm where?

[BlameItOnMyBro95]

lol...im doing this in AP bio!!

[TurnPaperWarioXGN]

haha that daphinia looks like its spazzing out! ^_^

[Generic1987]

This is why chemists and physicists say all that we do is look at things under the microscope and say "Ohh, look! An (insert microscopic organism name)! Isn't it cute?!"

[Kickasss119]

we r gonna be doing this in AP Bio for a lab, pretty fun lookn stuff

[FyerEgg]

its angry!! >=3

[jackerrspk]

so which is the heart, the end of the long tube or the thing that looks like a sardine?

[7410n0]

The heart is actually located near its back to the right of the long tube thing. It's not clear in this video.

[RiRiShi]

I did an experiment with Daphnia on friday. Seeing how caffeine affects heart rate.

[rddaos]

how'd that go

[RyanatorML2000]

Today, I fished a daphnid out of my culture of pond water. When I saw it with my naked eye, I thought it was a bug. Then, when I first saw it through the microscope, I thought it was a protozoan awaking from a cyst because it was all curled up in a ball! I saw something moving inside. Then it started to come out. When it got out, it started moving around like crazy in its micropond!

[BlockisticStudios]

Its cute. But that looks more like twitching than a heartbeat :P

[simplecrs13]

It looks like a bird

[OhMyGodItzMe]

that heart sucks

[makaveliasim]

can't see the heart

[ulamuro]

yeah i cant too. that stupid fish doesnt stop to move :)

[vidainsolita]

great!!! thanks for sharing!

[wirbelwindbattleship]

Is this the water flea?

[MaskguyEvan]

Daphnia and water flea are the same thing.

[Shandchem]

Brilliant photography, to show the daphnia so sharply in focus, at such a high magnification. Amazing to watch!

[bigezorange]

awesome
