I believe the black circles there are very small air bubbles. Notice that they have no internal structure, are perfectly round, very mobile, and refract light differently than the other objects.
@nagydoesstuff no I don't use a coverslip (which are typically glass and not plastic by the way). I can go without a coverslip because it is an inverted microscope so I'm looking through the water as it sits on the plastic petri dish. It would squeeze them but I doubt it would kill many.
@@Omnicurious Hi I am keen to know if you would be interested in us licensing a couple of shots of the plankton under the microscope to a tv drama series we are currently making in New Zealand. Thanks
I am a college student doing a UROP (research project) on the phytoplankton in the charles river. This video is very helpful in getting an idea of what to look for in a sample, what kind of microscope may be best, and what certain classes of these awesome animals look like. How are you IDing these things? Do you have any resources that may be especially helpful? pictures are great, (actually seeing these guys moving under a microscope gives me a way better idea of what to look for than a bunch of words on the page of an ID guide) but a text-based guide can also be very helpful. Can I ask what microscope you are using? I know almost nothing about this kind of thing but mu UROP director was going to have us buy a microscope for this project.
The microscope is a Nikon TS100 inverted phase contrast microscope. I just have my phone on a tripod here up to the eyepiece. I can identify to a pretty rough level by eye (I know what a copepod looks like) but identifying to a species or even genus level can be quite challenging. You can try posting images on iNaturalist or try to find a field guide/book.
I came from the future to tell you great video. Well done.
Thanks for this, I always was curious to collect ocean water to see what was in it but was always too lazy. Thanks for doing it for me haha!
Glad I could help! I'm thinking about collecting some samples from other sources and comparing them. Maybe a lake or river as well.
Very educational, great video!
What are the black circle things they are trying to eat at 5:48?
I believe the black circles there are very small air bubbles. Notice that they have no internal structure, are perfectly round, very mobile, and refract light differently than the other objects.
it seems to be making the bubbles. I wonder if it's using cavitation to get food?
@@byeFofiko1 cavitation is a pretty high energy process. Most likely some air bubbles just got trapped during the sample preparation.
Really cool video!
May I ask what microscope you are using?
Thank you! I believe it was the Nikon TS100 inverted phase contrast microscope.
Is it able to show live to other people on a TV?
This was very interesting to watch!
Thanks!
SpongeBob is the greatest cartoon
Plankton is the best copeopod!
do you put the little plastic piece on your slide? if not, would it squish the big organisms if you did?

@@Omnicurious alr man, thanks for the info
Bro you found plnakton so, where is mr krabs?
Hi there, I was wondering if there was a way I can contact you about this video and specifically your microscope footage. Many thanks
What do you want to know?

@@petersalmon9327 you can email me at samgreenberg25@gmail.com
4:51 looks like a barnacle nauplius to me
I think you're right! I guess I knew they had a free living stage, but I never knew what they looked like.
v informative vid ty
