Particularities: Distinct system of pharyngeal veins
Chaetonotus hoanicus is a very rare gastrotrich that has so far only been observed by Schwank. I would therefore like to describe it in more detail.Ch. hoanicus is the abrupt transition from an unspined (or shortly spined) head area to a relatively long spined back:
Ch. hoanicus: Change of the dorsal spination
The scaling of the neck/head area consists of almost round, strongly overlapping scales with only an extremely short - often only perceptible - spine:
Ch. hoanicus: Change in the dorsal scales on the neck
With an abrupt transition to long spiny scales the area of the trunk scales is clearly separated. The trunk scales are relatively large, roughly pentagonal and have a large cut-out at the rear end. Spines approx. 15-20 µm long arise from its tip, which are provided with a secondary tip distally.
Ch. hoanicus: Modification of the dorsal trunk spination
In the anal region there is a short spined field. Some conspicuous, longer spines protrude into the toe cutout.
Ch. hoanicus: Change in the dorsal spination of the anal region
The exact scale shape only becomes clear when it is possible to detach scales:
Ch. hoanicus: Individual dorsal scales from the dorsal region
The particularly pronounced tuning fork-shaped structure of the pharyngeal surface, which connects the oral cavity with the glands in the pharyngeal wall (see Pharynx ), is conspicuous:
Ch. hoanicus: Structure on pharyngeal surface
If one films a living specimen of Ch. hoanicus with the focus on these “veins”, a clear flow within these structures becomes visible, indicating a gland-like function:

(Hystricochaetonotus) For the subgenus Hystricochaetonotus are the relatively large, non-overlapping scales with a long spine. This subgenus owes its name to this spiny appearance (hystix = porcupine).
*Typical Chaetonotus (Hystricochaetonotus) - here
C. (H. ) persetosus
The scales are in typical arrangement. Their shape is trilobate with a central keel, at the end of which arises a long spine - usually with a secondary tip:

Hystricochaetonotus ; precise diagnosis required
Particularities: Spines without secondary tip; unique scaling of the ventral intermediate field
The small gastrotrich Chaetonotus (H.) italicus , previously only known from Italy, is relatively common in the Sima bog.
Ch. italicus: dorsal
Many of the specimens found were in their post-parthenogenetic (hermaphroditic) phase and bore both a distinct, bipartite X-organ and rod-shaped spermatoids. The pronounced dumbbell-shaped pharynx is typical of the species:
Ch. italicus: t.s.
The ventral intermediate field is covered with two rows of rectangular scale plates, which become more indistinct in the neck area. Two keeled terminal plates form the end:
Ch. italicus: ventral
Although the scale spines do not have a secondary tip, the classification in the subgenus Hystricochaetonotus is clear due to the typical scale shape:

Ventral scales: 2 long, thin terminal plates with short spines; 7-8 rows of small keel scales (1µm - 3µm)
Oecology: Moor, bank moss
Particularities: Toes naked; rigidly protruding spines are very typical
The very rare gastrotrich Chaetonotus (H.) murrayi is only known from two localities (in Poland and near Berlin). The strong and quite long two-pointed spines protrude in a spear shape and give the animal a very defensive appearance.
Ch. murrayi: cross section
This is particularly noticeable when focusing on the spines on the back:
Ch. murrayi: dorsal
The approx. 20µm long spines have a lateral secondary spine near the main spine:
Ch. murrayi: focus on the spine tips
The focus on the scales shows the typical three-lobed scale shape of this subgenus. In contrast to the findings in the literature, the entire head of the animals is also covered with long spines:
Ch. murrayi: dorsal scaling of the head / neck area
The spination is also clearly pronounced at the posterior end. Unlike many members of the subgenus Hystrocochaetonotus this species lacks the unspined dorsal keel plates:
Ch. murrayi: dorsal scaling of the hind end
The ventral intermediate field bears 6 - 7 rows of small keel scales and is terminated by two spiny terminal plates.

Adhessive tubes: 50% of furca
Pharyx ( cylindrical ): 27 µm - 51 µm
Diameter of the mouth ( round ): unknown
Dorsal scales: 7 rows on the head, 12 on the trunk, each with 14-15 three-lobed, keeled scales (3-6 µm), which do not overlap and are short and delicately spined (10 µm); two rows of longer spines at the head end. Very long spines with two secondary tips (26-50 µm) in a relatively narrow field on the anterior trunk
Ventral scales: 2 elongate-oval, keeled terminal plates (6.6µm x 4µm) with two simple spines; 4-6 rows with 40 oval keel scales each. Own observation: in pharyngeal region rectangular transverse claspers
Oecology: Moor, plant-rich small bodies of water
Similar species: C. (H. ) anomalus
is possibly synonymous; differs only by the absence of the two scale rows with longer spines on the head (which was present in my observations) and by scale claspers below the pharynx (which are also present in
Ch. novenarius in my observations).)
Particularities: easily delimited by the long spines that emerge from a narrow field
Chaetonotus (H.) novenarius is immediately recognizable by its nine very long large spines.
Ch. novenarius: dorsal
The nine large spines each have two secondary tips and extend beyond the end of the animal’s toes. Ch. novenarius is the Chaetonotus with the longest spines relative to the body length (approx. 2/3 of the body length):
Ch. novenarius: dorsal large spines
Although the scales and spines clearly identify the animal as Ch. novenarius , the ventral scales of the found animal are puzzling:
Ch. novenarius: ventral
Striking are the rectangular scale plates in the pharynx area, which Schwank only shows for the very similar species Ch. anomalus . It is possible that this species is a synonym of Ch. novenarius , as (Schwank, 1990)

Ventral scales: Ventral intermediate field on head 3 touching plates; otherwise elliptical plates; in gut region sometimes 3 deer of smaller elliptical plates.
Oecology: Bog waters, rare, very variable
Particularities: very variable with respect to spine size - possibly a number of subspecies
A very rare and strange ventral hardy is the nearly rotund Chaetonotus (P.) acanthocephalus with its irregular spination and large, round scales:
Ch. acanthocephalus: focus on the dorsal scale
Ventrally, the animal bears large cuticular plates on the head that change to round, short-spined scales toward the posterior end:
Ch. acanthocephalus: ventral
If the animal is macerated with glacial acetic acid, the scale shape typical for the subgenus Primochaetus becomes particularly clear:

Adhessive tubes: 75% of furca
Pharyx ( cylindrical, terminal swollen ): 31 µm - 39 µm
Diameter of the mouth ( round ): 8 µm
Dorsal scales: 10 rows of 20-25 strongly overlapping, rounded triangular scales (5 µm - 8.5 µm) with strongly convex margin (margin appears double) with short spines (7 µm); 7 - 12 simple girdle spines (6.5 µm - 16.5 µm) in alternating rows; scales behind spine girdle mostly without spines
Ventral scales: 4 elongated terminal plates with keel; 8-9 rows of small keel scales
Oecology: Moor, on mud
Similar species: well demarcated by spine belt and double scale edge
Particularities: Spiked belt and double scale edge
A further representative of the subgenus Primochaetus is the small abdominal hardy Ch. (P.) acanthodes , which is notable for its distinct, spineless scales with a “double” anterior contour and a belt of long spines on the abdomen:
Ch. acanthodes: dorsal scales
Only in the lateral view one recognizes that the spiny belt covers the entire dorsal side of the animal:
Ch. acanthodes: side view
The ventral intermediate field is covered with approx. 8 rows of small, roundish keel scales. The rear end is formed by four rectangular, narrow keel plates:
Ch. acanthodes: ventral scales
In cross-section, it becomes clear that the scales are strongly curved. This results in the “double contour” in the optical section. The animals I found have one or two teeth at the entrance to the pharynx:

Ventral scales: Ventral intermediate field with +11 rows of short spiny tiny scales
Oecology: Bog waters, among fallen leaves; common
Similar species: C. (P. ) heideri
: Spines are bent;
Particularities: brood care: decorating the eggs with detritus; var.
bernensis has no secondary tips
Ch. cordiformis shows in cross section the typical structure of limnic gastrotrichs. Remarkable are the relatively few, long and strongly curved scale spines:
Ch. cordiformis: cross section
The side view shows the enormous length of the spines which are provided with a secondary tip:
Lateral view (ChCordiformis2.jpg)
Ch. cordiformis: side view
These long spines make it very difficult to take good photos of the animals, because pinning them down with the coverslip strongly disturbs the natural arrangement of the spines. Therefore, an attempt should be made to capture the appearance of the animals free-swimming:
Ch. cordiformis: free swimming specimen with focus on the scale spines
High resolution images are only possible with somewhat pressed specimens. Only here the roundish scale shape with the scale spines provided with a secondary tip becomes visible. The secondary tip sits relatively far away from the spine end of the animals.
Ch. cordiformis: spiny scales with secondary tip .
Many of the specimens found had peculiar spherical bodies inside, which I think are (permanent forms? of) parasites:
Ch. cordiformis: spherical inclusions .
The scales of the animals can be judged well only after they are detached. Here you can recognize the name-giving “heart shape” of the roundish scales with an indentation:
Ch. cordiformis: heart-shaped scales
Ch. cordiformis is one of the few gastrotrichs that performs a kind of “brood care” after egg laying. After oviposition, the mother transports detritus from the vicinity of the oviposition site in her pharynx to the egg and sticks this material to the eggshell. As a result, the eggs are completely covered by detritus and protected by it from enemies:
