Very very large. Not like anything I have ever seen or can find. Perhaps it is an animal? It really doesn’t look like one

CHILODONELLA UNCINATA Ehrenberg (Kahl 1931) from the freshwater pond Kellis Pond which appeared after feeding the culture with boiled wheat seed. Imaged in Nomarski DIC on Olympus BH2 using SPlan 100 1.25 oil objective plus variable phone camera cropping on Samsung Galaxy S9+.

The cells measure 40 um in length, a bit smaller than Kahl's described range of 50-90 um. Foissner (1981) givers a range of 28-36 um, Song (1997) around 30 um, and Song et al. (2009) a range of 30-50 um. There are 4 left and 4 right kineties as well as two circumoral kineties and a single preoral kinety. The postoral region is devoid of cilia. The anterior dorsal brush row of bristles is visualized when the indivdual is viewed from the dorsal surface. The macronucleus is ellipsoid and situated posteriorly along with an ovoid micronucleus posterior to the macronucleus. The cyrtos forms a cornucopia-like basket and consists of 10 rods surrounding the circular cytostome. The two contractile vacuoles are diagonally opposed in the anterior right and posterior left quadrants of the cell.

CHILODONELLA UNCINATA Ehrenberg (Kahl, 1931) Length 50-90 um; body dorsoventrally flattened (cr., c. cucullulus); about 11 ventral ciliary rows; dorsally a transverse row of about 7 dorsal cilia or bristles (see Fig. 35B); cytostome round, cytopharyngeal trichites form a cornucopia; macronucleus oval; a single small micronucleus; the 2 contractile vacuoles are located in the anterior right quadrant and the posterior left quadrant, respectively. Chilodonella dentata Fouque is generally held to be a synonym of C. uncinata. Food Bacteria, diatoms, small green algae. Occurrence and ecology Cosmopolitan in distribution, found throughout the year in still and flowing waters (e.g., trickling filters, oxidation ponds). Often numerous in bacterial layers, e.g., at the surface of polluted waters.

Stentor muelleri EHRENBERG, 1831 from Pussy's Pond, a brackish offshoot of the estuary Acabonac Harbor. Swimming and fully contracted cells. Imaged in Nomarski DIC on Olympus BH2 using SPlanapo 40 0.95 and SPlan 100 1.25 oil objectives plus variable phone camera cropping on Samsung Galaxy S9+.

The extended cells measure from 400 up to 640 um in length. Individuals appear brownish in color and have a moniliform macronucleus composed of a chain of up to 20 ovoid to ellipsoid nodules. I could not observe the lorica since these samples have been disturbed [see discussion below item 8].

" Stentor has a mighty oral appar4tus on the margin of the
broad end. It is cornposed of hundreds of adoral
membranelles (plates of closely spaced cilia acting
together) which are, on the inner side, accompanied by a
single row of cilia, the so-called undulating membrane. The
ciliary plates, which are composed of 25 pm long cilia and
beat 30 times per second, form a spiral band, the so-called
adoral zone of membranelles, which plunges into a conical
buccal cavity leading to the cytostome (mouth proper).The
metachronal beat of the membranelles generates a strong
current swirling food organisms with a velocity of 800 pm s-1 into the buccal cavity" (5).

"Stentor muelleri Ehrenberg, 1831 10-20 macronuclear beads. Slenderly trumpet shaped and 500-1000 um (rarely up to 3 mm) long when fully extended. Mainly in freshwater, but also in estuaries. Recorded from Europe, North America and China . A detailed description and discussion of synonymy, morphology and ecology can be found in Foissner et al. (1992). This freshwater species is well defined by its moniliform macronucleus and the absence of pigmented cortical granules. It has-30-50 somatic kinetics and -10 peristomial ciliary rows. Stentor muelleri has two junior synonyms: S.felici and S.katashimai" (1)

Differential diagnosis from (2)

Elongated individuals in vivo up to 3 mm, usually 500-1000 um long.
Sessile, slim, trumpet-shaped, usually slightly curved. Contracts in an inverted pear shape.
About 10-20 spherical macronucleus parts, which in elongated individuals have a rosary-like form, forming a chain about half the length of the body. 10-17 micronuclei .
Contractile vacuole on the left wall of the oral funnel, with one collecting duct reaching far backwards.
In the plasma and between the cilia, very dense, colorless, granules about 0.5 pm in size. Appears yellowish to brownish at low magnification. No symbiotic algae.
Number of ciliary rows (about 70?) unknown.
The adoral membrane zone extends into the mouth in a spiral to the right. Number of the adoral membranelles unknown. Floor of the mouth with about 20 ciliary rows.
8] Sometimes found with extended, thigmotactic cilia in a 200-1000 um (usually 300-500 um) long, sac-shaped to bottle-shaped, slimy, sometimes very hyaline shell (case usually only noticeable in cells that have been undisturbed for a long time; then often densely covered with detritus).
"Comparisons S. polymorphus and S. coeruleus also have a rosary-shaped macronucleus. The former is colored green by symbiotic algae, the latter has light to strong blue granules between the ciliary rows. Smaller one (500-1200 um) and like S. muelleri uncolored S. roeseli, the macronucleus is rope-shaped. Characteristics 3 are particularly important for identification, 5 important" (2). " Stentor katashimai Kumazawa, 1973 has the main characteristics of s.muelleri, from which it is said to differ by the lack of a lorica, a more stocky shape and the possession of a buccal pouch (Kumazawa, 7974)" (1). "Stentor cornutus Kumazawa 2002 is more conical in shape when extended, while S. muelleri takes a characteristic, slender shape (Kahl, 1935), which is more like an uncoiled trombone (Tartar, 1961a) rather than a trumpet. Stentor cornutus never forms the cylindrical case that S. muelleri usually has when it is attached. The stiff cilia in S. cornutus are shorter, and much less conspicuous than those in S. muelleri. The macronuclear nodes are fewer and more spindle-shaped in S. cornutus than those in S. muelleri, which has more rounded, bead-like nodes" (3).

Fernandes et al 2012 reported a population of Stentor polymorphus devoid of symbiotic algae. They based their diagnosis largely on the absence of loricae in their population and by the presence of a large peristomial pouch (4). The lorica is not always seen in S. muelleri and Foissner et al 1992 attached little importance to its presence (2). The buccal pouch was discounted by Foissner et al 19922 (2) as being a weak character insufficient to discriminate species (2). However Kumazawa 2002 disagrees and stressed presence of the large pouch as an important discriminatory character between their new species S. cornutus as well as S. katashimai (3). Kumazawa 2002, in his figure 1, illustrates the large buccal pouch in S. polymophus (figure 1a) and the lack of same in S. roseli (figure 1b) (3). My observation here has an identical buccal cavity to Kumazawa's figure 1b which he states demonstrates a species lacking the buccal pouch. This serves to differentiate my observation from an aposymbiotic population of S. polymorphus. In addition, the S. polymorphus population of Fernandes et al 2012 had an in vivo length of 850-2000 um, quite a bit larger than my population of S. muelleri at 400-640 um (4).

"Occurrence and distribution: Approximately equally common in stagnant and flowing waters, much rarer than Stentor roeseli. SCHMARDA (1846) found it in all seasons and slow-flowing waters near Vienna. Also in the mesosaprobic samples from Amper near Munich fairly regularly and with a focus on appearing in May/June. We found 1 specimen in the activated sludge. According to ALBRECHT (1984), S. muelleri is oligo- to mesoeuryhaline (see also the evidence from KAHL 1933) in the mouth of the Weser, from BIERNACKA 1962 in the Bay of Danzig, by RIEDEL-LORJE 1981 in alpha to betamesosaprobic samples Elbe Estuary and by JONES 1974 from an estuary in the USA with (0.2-3% salinity). So far only in Europe and Asia (SHEN YUNFEN et at. 1988) and North America" (2).

Stentor multiformis (Mueller 1786) EHRENBERG, 1838 from Pussy's Pond, a brackish offshoot of the estuary Acabonac Harbor. Imaged in Nomarski DIC on Olympus BH2 using SPlanapo 20 0.70 and SPlanapo 40 0.95 objectives plus variable phone camera cropping on Samsung Galaxy S9+. The cells have a lovely pale green-blue coloration without symbionts. However, using my Nomarski DIC, I could not bring out the lovely blue-green coloration no matter how I adjusted my DIC slider and the camera settings. I did manage to capture the color under conventional bright field. They are mostly swimming and only rarely are seen to attach to the substrate. The length on the swimming form is 200 um. There is a single spherical macronucleus.

"Stentor multiformis (Müller, 1786) Ehrenberg, 1838 (basionym: Vorticella multiformis). A detailed description and discussion of synonymy, morphology and ecology can be found in Foissner et al. (1992). This is a small, blueish species occurring in marine, freshwater and terrestrial biotopes. It is, however, still uncertain whether the marine and freshwater populations are truly conspecific. In the absence of detailed evidence, we follow Stein (1867) and Kahl (1932), who assume conspecificity. This species is sparingly mentioned in faunal lists, although it is rather frequent (Schuberg, 1896; Foissner et aI.,1992); possibly it has often been mistaken for small individuals of S.coeruleus, Stentor multiformis has 34-45 somatic kineties, 6-9 peristomial ciliary rows and 100-150 adoral membranelles (Packroff and Wilbert, 1991). Two junior synonyms are known: S. gallinulus and S.nanus" (1)

"All evidence before 1900 come from marine biotopes. KAHL 1932 found S. multiformis both in very weak brackish water as well as in the sea. Later it was found in flowing and stagnant waters, i.e. in fresh water repeatedly. Possible confusion- The also blue-green S. coeruleus has a moniliform macronucleus and is much larger (1-2 mm). Features 3 and 5 are particularly important for identification. Always pay attention to the macronucleus" (2).

"Occurrence and distribution: In the benthos and growth (also scum skin) of brackish water ponds among other things, the North and Baltic Seas, the Atlantic and the Pacific (2nd B. BIERNAKA L962, LEVANDER 1901, MÜLLER 1786, STEIN 1867, WAILES 1943). According to KAHL (1933) a typical salt water form. According to the later literature data and our own experiences, also in Lakes and ponds ( BOVEE 1960, GAJEWSKAJA 1933, GRABACKA 1973, PACKROFF & WILBERT 1991, SCHLOTT-IDL 1978, SCHUBERG 1896; own observations from the strong eutrophs Salzburg University Pond and not too rarely in flowing waters (ALBRECHT 1984, PATRICK et al. 1967, REUTER 1963; own observations in the beta to alpha mesosa samples Amper near Munich. PUYTORAC et al. 1972) once found it very often in a small, eutrophic, sphagnum-covered lake near Montreal (Canada). Further evidence in Central Europe European moorland waters: GROLIERE (1977b), PENARD (L922). So far found in Europe, Asia, North and Central America and New Zealand" (2).

"Differential diagnosis
1) Length in vivo 200-500 um, usually around 250 um. Contractile down to 90 um.
2) Trumpet- to obversely pear- or bottle-shaped. Bottom of mouth on the right bulging like a comb.
3) In the middle of the body there is 1 (very rarely 2-4) round to slightly ellipsoid macronucleus, containing many small, flattened micronuclei.
4) Contractile vacuole on the left wall of the oral funnel, with a short anterior collecting duct on the left and a long one posteriorly.
5) Close under the pellicle, between the ciliary rows, very densely packed, azure to sea green granules that form narrow stripes and give the cell a bright appearance at low magnification with strong blue color. No symbiotic algae.
6) 34-45 ciliary rows, the space between which increases in a clockwise direction. Between the short somatic cilia, which can be spread apart, there are also long, stiff tactile bristles.
7) The adoral membrane zone extends into the mouth in a right-handed spiral and consists of from 100-150 adoral membranelles. 6-9 rows of irises on the floor of the mouth. Parallel to the adoral membranelle zone there is an undulating membrane.
8) Lorica housing has so far only been proven by PACKROFF & WILBERT." (2)
