Aspidiophorus paradoxus is the largest Aspidiophorus species with about 300µm length.

Fig. 1: Dorsal scales.

The entire animal is covered with relatively large rhombic peduncle scales.

Fig. 2: Cross section

In cross-section, the structure of the peduncle scales can be clearly seen: the scales sit with a small basal plate on the cuticle of the animal, from which a thin, hollow peduncle rises. At the end of the peduncle sits a rhombic terminal plate, with a central keel. At the posterior end of the animal, the terminal plates of the last row of scales are enlarged.

The pharynx of the animal is terminally swollen, and the head is weakly five-lobed with two separate pairs of palpal tufts.

Fig. 3: Ventral view.

Ventrally, the strong hypostomion behind the mouth opening is striking. The two ciliated bands split at the head, but the inner branches do not unite in the population I examined. The base of the toes does not bear scales, the adhesive tubes
measure about 50% to 70% of the toe length and taper to a point.

Let's take a closer look at the scales:

Fig. 4: Back scales

In the scales on the back, the rhombic shape of the end plates can be seen most clearly. Less conspicuous - but typical for the species - is the middle keel of the scales.

Fig. 5: Cross section of scales

In cross section the complex geometry of the peduncle scales becomes clear - base plate, peduncle and end plate form a very flexible and stable carapace. The additional cavity under the outer scales acts like a "crumple zone" and further increases the protective effect.

Fig. 6: Cross-section of scale stems.

The stems of the scales consist of hollow tubes that ensure maximum stability with minimum material input - a fascinating example of evolutionary optimization.

The abdomen of the animals is not completely covered with petiolar scales. Rather, they end in the anal region and are joined by simple small, rounded keel scales that are not an obstruction to feces.

Fig. 7: Scaling of the abdomen.

At the furca base some (according to literature 4) spines protrude into the toe cutout.

The head is almost completely covered with slightly smaller peduncle scales:

Fig. 8: Head scales

Cephalion and pleurae are quite small and inconspicuous.

According to literature A. paradoxus has three teeth in the pharynx:

Fig. 9: Mouth armament.

In the animals I examined, only a curved stylet brace was found, the tip of which protrudes into the lumen of the pharynx and probably serves to open algal cells that are conveyed past it. It is possible that the literature reference to "three teeth" is merely based on a microscopic artifact, as the entire clasp may not be in the focal plane as a whole.

Chlamydodon species consistent with C. exocellatus

Sample from the road end at Harbor View Lane where there is a marine channel between Gardiner's Bay and Three Mile Harbor. The cyrtophorid ciliate genus Chlamydodon is characterized by a unique cross-striated band (CSB) along the cell perimeter. To date, more than 15 nominal species have been assigned to this genus, all of which are exclusively from marine or brackish water" (1).

My ciliate was very fat and colorful in that the cytoplasm was literally stuffed with ingested food: green algae and larger red globules in a background of smaller golden yellow globules. Being so well fed, it was impossible to see much internal detail. The cyrtos with toothed nematodesmal rods surrounding the cytostome was not visible nor was the anterior pigment spot and the peripheral cross striated band characteristic of the genus was only partially visible. I took a couple of videos and placed the slide in a humid chamber to allow the little fellow to digest and egest some waste.

The next morning much more morphological detail was visible. The ciliate was now much slimmer and most of the ingested food was gone though the cytoplasm was still full of golden yellow granular material. I could see that this 212 um long ciliate has a continuous cross striated band. The cyrtos consists of 19 toothed nematodesmata. There are in excess of 40 vacuoles scattered all over the body, 5 that are somewhat larger than the more numerous small ones. There is a central ovoid macronucleus. Strangely, I still could not appreciate the characteristic yellow or purple anterior pigment spot.

The above parameters are somewhat consistent with Chlamydodon bourlandi Qu et al 2018 but perhaps more closely resemble another nominal species, C. exocellatus Ozaki & Yagiu, 1941, Snoeyenbos-West et al., 2004. "Chlamydodon bourlandi sp. nov. has a cell size of 150–250 × 65–150 µm, a complete CSB, a reddish to violet cell colour, 83–97 somatic kineties, and 40–68 contractile vacuoles" (1). Qu et al consider Chlamydodon exocellatus sensu Snoeyenbos-West et al., 2004, to be an earlier population of C. bourlandi (1). The former has only 5 contractile vacuoles whereas C. bourlandi has >40. My Chlamydodon has 5 larger vacuoles clustered toward the anterior end of the cytosome in addition to the numerous much smaller vacuoles. Perhaps these smaller ones are the empty food vacuoles created during the overnight diet I inflicted on the ciliate and should not be counted as contractile vacuoles.

Qu et Al state: “Chlamydodon exocellatus sensu Snoeyenbos-West et al., 2004 resembles the new species (C. bourlandi) based on the cell size in vivo (150–230 mm vs. 165–215 mm in the present isolate), the number of somatic kineties (83–97 vs. 87–97), and the number of nematodesmal rods (14–19 vs. 14–17). Although there was no mention of the number of contractile vacuole, we think C. exocellatus sensu Snoeyenbos- West et al., 2004 was misidentified and it should be an early population of the C. bourlandi sp. nov. However, these two populations share a low similarity (94.1%) of the SSU rRNA gene sequences” (1).

Gong et al (2) point out that C. exocellatus lacks an anterior pigment spot like my Chlamydodon and none is depicted by Snoeyenbos-West et al., 2004 (1-fig 45) while Qu et al (1-figs.43 and 44) ) show that C. bourlandi has a purplish pigment spot. Qu et al also show that C. bourlandi also has a ridge from cytostome to posterior end; two grooves longitudinally positioned on dorsal side, on both sides of ridge which I do not see in my Chlamydodon. C. exocellatus can be distinguished from C. bourlandi by a rounded body shape with both ends broadly rounded vs. anterior end widely rounded and posterior end obviously narrowed to pointed in C. bourlandi (1). Finally, C. bourlandi has a purple coloration while my Chlamydodon has a golden yellow coloration.

Thus, I conclude that my observation is most likely C. exocellatus. Imaged in Nomarski DIC using Olympus BH2S under SPlan 40x objective plus variable phone cropping on Samsung Galaxy S9+. Some screen caps further cropped.

Lacrymaria marina Kahl, 1933 syn. Lacrymaria olor var. marina (O.F. Müller, 1786) Kahl, 1933

It's sexy time for the marine Lacrymaria. Last night I was looking at a slide of my latest sample from the intertidal benthos of marine estuary Accabonac Harbor which had an interesting polychaete and numerous Lacrymaria. I put the slide in a moist chamber overnight and when I reexamined it this morning I found a veritable sex orgy of conjugating pairs dancing their sensual ballet while exchanging genetic material through their mouths. There were equal sized pairs and unequal pairs where one was much smaller. One such unequal pair had the larger partner undergoing transverse fission while conjugating with a small partner 1/4 the size of the larger partner. Another uneven pair had globular bodies and the larger partner had a massively enlarged broad neck. Some pairs got tired and both went into the contracted resting state characteristic of Lacrymaria. Fascinating stuff. Imaged in Nomarski DIC using Olympus BH2 under SPlan 40x and 20x objectives plus phone cropping on Samsung Galaxy S9+.

A lot of images here to show all aspects of the sex orgy. We start with a teaser GIF of conjugation of two normal individuals. Then an illustration from the supporting reference and a picture of the sample site. Then some screen captures of a typical individual. Then screen caps of a fissioning individual. Then screen caps of conjugating pairs in various metabolic states- two equal sized individuals, two semi-resting individuals, two bizarely shaped individuals, and finally one normal individual conjugating with one undergoing transverse fission! Finally, I show GIFs of the various types of conjugating pairs in the same order as the screen caps. A lot of stuff!

Lacrymaria marina Kahl, 1933
Diagnosis. Body size 150-300 × 20-25 μm in vivo; extended spindle to vase-like shape; highly contractible neck; cell colorless; cortical granules colorless, regularly
arranged in between somatic kineties; single contractile vacuole, conical shape and located terminally; papillary head with obliquely arranged oral ciliary rows, 10-12 in number; spiral somatic kineties on contracted body, 17- 20 somatic kineties; 1 ellipsoidal macronucleus. Distribution. China, Germany, Korea (this study).

Remarks. Lacrymaria marina Kahl, 1933 can be separated from L. olor (Müller, 1786) Bory de St. Vincent, 1824 by the number of macronuclear nodules (1 vs. 2),
and habitat (saline water vs. freshwater) (Kahl, 1930). Lacrymaria marina can be separated from L. nana (Vuxanovici, 1961) Song and Wilbert, 1989 by the number of somatic kineties (15-20 vs. about 13), the shape of contractile vacuole (conical vs. spherical), and the position of the contractile vacuole (terminal vs. subterminal) (Song and Wilbert, 1989).

Above descriptions from:
Brief descriptions of 12 ciliate species previously unrecorded (Protozoa: Ciliophora) in Korea. Ji Hye Kim and Jae-Ho Jung. Journal of Species Research 6(Special Edition):15-25, 2017. https://www.researchgate.net/publication/322212723

From Bruce Taylor: From saltwater, with a single macronucleus, posterior vacuole, approximately triangular (possibly a defecatory organelle, per Song & Packoff). Apparently somewhat less extensile than L. filiformis (a freshwater species), bigger than L. nana, lacking the tail-like process of L. acuta.

L. marinum Kahl, 1933 is the same taxon as L. olor var. marina (O.F. Mueller, 1786) Kahl, 1933.

Doesn't feel like it's commune in general. The capsules for pallidisetum are described as tan, but seem red in LOTS of photos, esp the one in the Princeton Field Guide to Mosses, and many of the traits match descriptions within said field guide (such as red tipped leaves; boxy & bent over capsules).

Perianths are huge compared to other Suaeda spp. 4-5mm on some with strongly keeled sepals giving a sharp star-shaped appearance. Glomes not crowded, but rather sparse with 1-3 flowers. Seeds dimorphic. 1.5-2mm or so. Would like to hear some opinions on this confusing genus/species. Keys out to rolandii better than any other species. Location is general since it's rare. Growing in upper salt marsh. @zihaowang, check this out.

Seeds dimorphic, which rules out S. maritima. Seeds well over 1.7mm wide, which rules out S. calceoliformis. Perianth segments keeled and very thick. Fits well with S. rolandii (the only other species known from the region). Specimen was collected roughly a kilometre from site where in situ picture was taken.

In Ecology Park, Brooklyn.

I'm going long on this one, and hypothesizing a species. I can't find any other small yellow bee that could occur in the area of NYC.
