Also we've had other labs looking at them, so we knew em when we saw em.
F. General Comments/Observations
Mostly the Daphnia were seen out and about in the less clumpy parts of the slide. They can't respirate without moving, so most of them die when they get trapped by the slide cover :c It's always neat to get a look inside at their little hearts going.
2) Organism 2: Naupilus Larva of unidentified crustacean (possibly copepod?)
A-C. Taxonomy:
Domain: Eukaryote
Kingdom: Animalia
Subkingdom: Bilateria
Phylum: Arthropoda
Order: N/A
Family: N/A
Genus: N/A
D. Defining characteristics of organism
Naupliar eye
6 eyes
Proportionally large abdomen
Translucent chitinous shell

The Good Boys blog post helped me figure out when it was kind of like a water mite or some other crustacean but not one I could pinpoint

He hopped around a bunch! The locomotion of this guy was super jumpy and sudden and I think he tended to jump around more when the slide was actually moving or vibrating itself.
3) Organism 3: Ostracod
A-C. Taxonomy:
Domain: Eukaryote
Kingdom: Animalia
Subkingdom: Bilateria
Phylum: Arthropoda
Order: Metacopina
Family: Cyprididae
Genus: Cypridina
D. Defining characteristics of organism
HE'S A BEAN
Opaque carapce shell in adult form
Small legs on bottom
Very cute and small
Can't see inside him though

What a cutie honestly. There's not too much to observe other than the locomotion is small and a little twitchy.

These guys are pretty much everywhere. The spin where ever they so please so it's kind of hard to get one under a high enough magnification to make out what's going on structurally.
Other stuff we identified!
Shelled Amoeba
Flatworm
Roundworms
Plenty of of filamentous algae
Such a nice post!!! I pretty like like how you guys took the vlog to illustrate what you were doing in lab. Honestly, I really enjoy watching the vlog. Back to what organism you found, I think you guys kinda cool when you could find the organism #2, the one you proposed copecod. I think that one could be in the same order with Daphnia, because it seems look like a water flea to me, so I think Daphnia and this organism could be closely related together. One more thing, we also found the Chlamydomonas in our pond sample, but we could not identify it because it didn't showed any identifiable characteristics. Last but not least, nice labels and clear photos as usual.
ReplyDeleteNice photograph of the Daphnia! I noticed that some of the groups (including mine) had an obscured view of the Daphnia, so I find it great that I can easily see the organism under one of our microscopes. However, I wish I was able to find more types of arthropod organisms. In fact, I am quite surprised that some groups managed to do so as certain organisms seemed to be more commonplace than others. One group was able to find and identify a Nauplius, for instance. Nevertheless, I admire your dedication to labeling each of your pictures, creating a nice documentary of your lab endeavors, and including a GIF of your green algae specimen. Nice job in providing clear and well-organized information!
ReplyDeleteYour post is great! Its very organized, and making a vlog was really creative, and I think it especially nice that you inserted taxonomic ranks for some of the organisms in the video. I also think its very interesting how many moving creatures you found in the water (Naupilus Larva, Ostracod, and the green algae). And it was nice how you inserted videos so we could see all the other creatures you found in the pond water.
ReplyDeleteIts always so intriguing to find out all the different creatures living in water, and I think the Naupilus Larva you found is super interesting, as it has six legs, and I've never seen anything like it. I definitely agree with Thinh in that it could be in the same order as Daphnia, as it is in the same Domain, Kingdom, Subkingdom and Phylum. Altogether, I really liked your post!
Hi Gwen!
DeleteHere is my comment for Pond Water...
BUT WHAT ARE YOU?!?!?!?!?
ReplyDeleteBUT WHAT ARE YOU?!?!?!?!?
ReplyDeleteI really like how you guys took some videos and posted them in your blog, so we can all see clear pictures of the samples. I just noticed that you guys have a typo in organism 4:Green Algae (Chlamyolomonas)and it's supposed to be(Chlamydomonas), you can always fix that. other than that everything look very organized and clear. I also found out that the Green Algae (Chlamydomonas)can be found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae which is very interesting. Again very great job guys.
ReplyDeleteOh thanks for pointing that out! It's now fixed c:
DeleteHi guys!
ReplyDeleteGreat job! I was attracted by your video when I saw your post at the beginning, because I can see all the organisms clearly from your pond water sample via this video. Also, the explainations and the labels are very detailed in the video too. After that, there are many different pictures about the organisms were displayed, and labeled by a lot of imformation, to us their phylum, kingdom, domain and so on; it is great too. I think you guys had very nice pond water sample because there were plenty of organisms be found and be recognized. I appreciate what you guys did!

Great post! I admire how creative you were with your videos and pictures. Your blog was very well organized. It was fascinating to see all those organisms that were in your slide.
ReplyDeleteHi guys! First off, I wanted to say that I thought your GIF was very cool. I was first attracted to your post because I feel like we are always trying to find ways to show people how we are finding these organisms in lab, but sometimes it can be very difficult. Your GIF makes it very clear what you are looking at and it is very cool to get to see it from your perspective. You guys are very descriptive and it makes it very easy to understand your info. There was obviously some great lengths you guys went to find your organisms. I mean, you even found a bean! But really, good job organizing it and explaining all of your findings. Great job as usual guys!
