At one time "Euglenophyta" was in the "Plant Kingdom". DNA determinations resulted the designation "Protist". See Wikipedia: "Euglena", "Euglenoidea", and "Euglenophyta". Taxonomy by picture is risky, which is why I used the term "Euglena-like". Present are red "eyespots", chloroplasts, and a pellicle. I saw no evidence of a flagellum. The water salinity was 82-PPT [see the description].
You are indeed lucky to be in a school where science and biology are taught.
These salt-water Euglena only lasted a few weeks. They vanished as the salt concentration got higher. Now an entirely new group of microorganisms live in the Weep.
Videomicrographs were taken in 30-second segments at standard video frame speed with a Nikon Coolpix 885 camera screwed to the Zeiss eyepiece with a Nikon UR-E4 ring.
Olympus Hoffman Modulation Contrast optics supported on a modified Olympus Irvine 6X6 trinocular; a Cole Parmer High Intensity 150W Illuminator attached via a 3/4″ lucite rod light conductor; 10x eyepieces and a 10x Zeiss screw-top eyepiece in the trinocular camera mount. Very high light intensity is required for HMC. A simple wet mount of a 1-microliter sample was used. Stop cock grease was used around the edge of the coverslip to anchor it firmly and prevent evaporation.
By shape, could be any of several species of Euglena. The salt marsh pond was considerably saltier than "brackish" - although evaporation had been very rapid and proliferation may have taken place at a lower salinity. No cultures made, all gone the next visit [salinity even higher].
They look like... peapods... Like, mutant peapods...

Euglena Sucks!!!

What does it mean by "Euglena-like"? Wasn't this protist at one stage classed off in the fungi "kingdom"?

There's no way that these could be even close to euglena. There aren't a flagella and an eyespot,and I think the things in the video are way to big.

im studying this in 6th grade science
[im in 6th grade]and my science teacher showed this to my classmates on her
laptop/overhead,and it was soooo cool!!

Good Quality images. What scope and camera were used?

Nice, very crystal clear, very detailed.

It wasn't crystal clear but it was clear as possible.
