Euglena spyrogyra Euglena spyrogyra Ehrenberg1832. A medum-sized euglenoid, distinguished by its textured pellicle. At the end, a cyclops nauplius stops by to check him out.
Snake-like euglenoid This is an old video, about four months old. This is a flagellate, probably of the genus Euglena. I would like an ID. It is long, thin, moves similar to a snake or a nematode, and has a black eyespot.
Dinema / Dinematomonas (possibly litoralis) A non-photosynthesizing euglenid, with a trailing flagellum. This one, from bottoms sediments in a pond near Wakefield, Quebec, is about 60 micrometres long. Dinematomonas is synonymous with dinema (Silva, Remarks on Algal Nomenclature, 1960) Comprehensive description of D. litoralis at EOL: It might be also be D. dimorphum (described in Schroeckh et al., Hydrobiologia 493:131-166, 2003), and reported in fresh water (whereas D. litoralis seems to be a marine species, usually). However, I do not see the spiral groove reported for this organism. 400X
Phacus (a euglenoid) This is a four-month-old video. It is a short clip of a Phacus, a euglenoid like Euglena, but flatter, like a leaf. The red eyespot, the thick body, and the "wings" on both sides are visible, as is the stub of the flagella.

Euglena - Disciplina de "Algas e Fungos" 2011/12 - Lic Biologia (Univ Coimbra) Euglenoid flagellates occur in most freshwater habitats: puddles, ditches, ponds, streams, lakes, and rivers, particularly waters contaminated by animal pollution or decaying organic matter. Usually larger bodies of purer water, such as rivers, lakes, and reservoirs, have sparser populations of less common euglenoids as planktonic organisms.
Euglenanimation There are certain organisms in the realm of the microscopic that are particularly fascinating. This animation is a brief documentary on the intriguing euglenae. It can be plant, or it can be animal.
Bdelloid Rotifer Part 4-Habrotrocha side view This is another short video of a bdelloid rotifer in the combo water sample. This is the fourth part of "Bdelloid Rotifer", a short collection of these animals. This video shows detail of the trophi (jaws) and crown of cilia, vsible from the traditional side angle, and background Navicula diatoms and assorted motile algae are visible also.

Feeding by Collotheca ornata - a large rotifer This is the beautiful rotifer, Collotheca ornata, that possess a large funnel-like corona that is studded with very long and fine bristles. This coronal type enables this organism to trap prey such as Trachelomonas, a Euglenoid. If the rotifer is disturbed, it will quickly collapse and pull down, only to slowly redepoy the bristles for feeding. This organism was collected at The University of Akron field station in Garden Pond at the Bath Nature Preserve in Bath, Ohio.

Euglenoid Vacuoles Evacuating This little guy is dying from dehydration. As they wind down, they expell internal water or poisons through contractile vacuoles, which can see going on here. if you know the name of this bug, please let me know.
Large, unidentified euglenoid This is an old video of a quite large euglenoid. I would estimate it to be larger than 150 µm. In the video, it is swimming slowly, and is stretching its body through metabolic movement. It appears to be E. gracilis or viridis except for the size. I'm not up-to-date with euglenoids, so can anyone identify this?

Euglenoid on Knops Pond During the summer of 2011 we found this rust colored material in large areas of Knops Pond in Groton Massachusetts in the part of Knops Pond that is called Red Water Cove.The depth of this material was about twelve inches and it reached out from the shore about fifty feet or more. At one point it stretched around the shore line for several hundred yards. It was later identified by Aquatic Control Technology Inc. as euglenoid which is unicellular flagellates, commonly found in freshwater especially when it is rich in organic materials.

The Killer Trypanosoma cruzi is a species of parasitic euglenoid trypanosomes. The species causes the trypanosomiasis diseases in humans and animals in America. Transmission occurs when the reduviid bug deposits feces on the skin surface and subsequently bites; the human host then scratches the bite area and facilitiates penetration of the infected feces. Human American Trypanosomiasis, or Chagas disease, is a potentially fatal disease of humans. It has two forms, a trypomastigote found in human blood and an amastigote found in tissues. The acute form usually goes unnoticed and may present as a localized swelling at the site of entry of the parasites in the skin. The chronic form may develop 10 to 20 years after infection. This form affects internal organs (eg the heart, esophagus, colon and the peripheral nervous system). Affected people may die from heart failure. Video edited by MJM Alves and W. Colli USP Brazil
Small, disk-shaped euglenoid (ID needed) This is an old but interesting find from my lake water. It at first appears to be some sort of non-motile algae, but then the red eyespot becomes visible. This is clearly a euglenoid, but I really want to know what type. Does anyone have an idea?
Heteronema "Heteronematine euglenid, colourless, phagotrophic, non-rigid, elongated, tapering, unflattened cells, some with moderate euglenoid movement others very metabolic, skidding or gliding; two flagella both emergent, unequal in length and thickness, the longer (thicker) one directed anteriorly during swimming or gliding, the other trailing but not attached to body; c*** opening subapical; muciferous bodies may be present, common and widespread genus in fresh and marine waters; cosmopolitan; Boundaries of genus are not easy to determine. Type species H. marinum Dujardin, 1841."
Phacus orbicularis - A Euglenoid I found this guy in a recent centrifuge run of some samples from my microbe aquarium. His flagellum is not visible here, but it can be seen when looking through the eyepieces. It comes out of the end with the red eye spot.
Gastrotrich There are several other nice videos of gastrotrichs posted on this site, but I decided to add this one because I think it emphasizes an interesting point. Gastrotrichs are among the very smallest MULTICELLULAR ANIMALS. So small, indeed, that they are sometimes dwarfed by the larger single-celled organisms. In this clip you see a freshwater gasrtrotrich and, near the beginning and again near the end, you see a single-celled, green Euglenoid that is much larger. The clip was captured on a consumer point and shoot digital camera (Nikon Coolpix) mounted on a Nikon phase contrast microscope.

Euglena metabolis demonstrating metaboly This video displays euglenoid movement or metaboly produced by the sliding of a series of longitudinal proteinaceous pellicle strips that are spirally arranged around the organism. This worm-like movement is unique to the Euglenoids and in what better organism to show metaboly than E. metabolis, collected from an acid mine drainage site in NE Ohio on 10-16-2009. The last two sequences were shot on 3-10-2012 of E. metabolis taken from a large finger bowl of the earlier collection stored in a culture chamber at 60F. This species usually forms cysts which allow them to survive adverse conditions.
Euglenoid with symbiotic algae Euglenoid (?) loaded with symbiotic algae
Euglena sp. Euglena slowed with methylcellulose. Note the flagella and red stigma.
Volvox Dances Volvox was once described as "the first multi-cellular plant." Now it is generally thought of as a colony of algae cells that have made a sort of "long-term commitment". However you think of it, Volvox reproduces both a***ually and ***ually and the progeny always grow into the colony. The shots for this film were made at 100X magnification with a Swift FM-31 Field Microscope and Nikon Coolpix 885 Digital Camera. The sample was collected along the creek bank at Muir Beach, California. The dark "balls" inside the Volvox colonies are daughter cells or daughter colonies.
Euglena Euglena was my very first favorite protozoa. They have what I would call the best of both worlds. Chloroplasts in which they perform photosynthesis, and they are also quite capable of eating small bacteria. This little movies illustrates the presence of its flagella and red eyespot; a more highly developed photosensitive area on the body, than its chloroplasts.
