We saw
Nauplius as the only organism in this list that moved around the slide. The
chloroplasts were not visible in this Spirogyra. The chloroplasts were visible
in the Coleochaete, as shown by the green color, and it was a little squished
by the cover slip. In the Chains were visible, but chloroplasts were not
visible.
Hey guys, I am unable to see any of your pictures on both Chrome and Edge browsers. Perhaps try to edit, download the pictures and directly drag them into your post so that it does not have to draw the picture from a link.
ReplyDeleteHey Chris, thanks for that! I think I fixed it, but let me know if you still can't see them. Thanks again!

ReplyDeleteOOoo props on finding out that was a nauplius! I saw the same organism and was uming and ahing about whether it was a water mite or not, but a larval naupilus form of a crustacean looks like exactly the thing!
ReplyDeleteHey guys,
ReplyDeleteI was looking through the posts and really thought your Nauplius was cool. In the samples that I had been seeing there was a lot of algae but nothing with six legs and that cool looking. In my side I had a moving creature that I couldn't identify but it didn't have such defining characteristics like 6 legs. Mine was just kind of a blob. Definitely a good job finding it and figuring out what it was on the internet.
Thanks!
