Daphnia longispina (Water Flea)

I'm new to video microscopy but already getting nice results. This was filmed with a simple point and press digital camera through an SP100 microscope.
See a water flea's heart beat, see its eggs, and watch it going to the toilet in slow motion ;-)

KAMI?!?!?!

beautiful!!

Is it weird that I think they're really cute...?

Nice vid, but D. longispina has a tail spine greater, sometimes much greater, than half the carapace length (longispina = long spine). I agree with Pond WaterWorld that this is probably D. pulex, it is certainly not D. longispina. Be wary of Google Images - most images are wrong, and many can be misleading. Try 'The Genus Daphnia' by John A.H. Benzie - expensive, but worth it.

I like your video very much. However, this specimen appears to be Daphnia pulex. Daphnia longispina is longer in length and is less fat. Still, great video. But no thanks for "going to the toilet in slow mo".

-
Nice! I got a end-of-year science class where I must study the effect of various chemical substances on the Daphnias heartbeats...

Thanks Bucketbox. The song is one of the freebies you find in the Audioswap section of Youtube. Sorry, can't find it again; I just picked one that sounded nice at the time. It's in the instrumental category somewhere

Many thanks!
Re finding the species, I rely heavily on Google Images ;-)

Thanks. It a trinocular scope (SP100) and I just pressed it against the lens and tried not to shake too much. Very low tech ;-)
