“…Larval worms, especially, have low host specificity (Palm and Caira, 2008) and a wide zoogeographical, or even cosmopolitan, distribution (Palm 2004, Palm et al 2007. Being widely distributed from brackish waters into the deep sea, the highest species diversity of trypanorhynchs can be found in coastal tropical waters of the Indo-Australian region (Palm et al 2009).…”

The genus Grillotia Guiart, 1927 is cosmopolitan in its distribution and the type-species, G. erinaceus (van Beneden, 1858), has been relatively well studied. However, this study provides infection indices of Grillotia erinaceus from southern and northern Black Sea whiting Merlangius merlangus for the first time. The specimens of Grillotia erinaceus were obtained from subserosa of the anterior oesophagus, stomach, pyloric caeca, liver, ovaries and mesenterium of whiting caught by commercial fishing vessels off Sinop, Turkey and off Balaklava, Ukraine. Fish were examined during the period from May 2011 to April 2012. Prevalence and mean intensity values in 268 fish collected off Sinop in the Black Sea were 18.66% and 1.82 ± 0.16 parasites per infected fish, respectively. In Ukrainian 166 whiting samples collected off Balaklava in the Black Sea, however, G. erinaceus plerocercus infection prevalence was 10.24% and mean intensity 1.71 ± 0.75 parasites per infected fish. Infection parameters were also determined at both sampling sites in relation with host length, sex and season.

“…Studies on microtriches suggest that they may be of great systematic and phylogenetic value (Richmond and Caira 1991). Microtriches have multiple functions such as amplification of the surface area for absorption and digestion, excretion, movement and external protection (Jones 1998, Palm 2004.…”

“…Two main types of microtriches have been described in cestodes: filiform microtriches (or filitriches) and spiniform microtriches (spinitriches), each including several subtypes (Faliex et al 2000, Palm 2004). In the basal groups of the Cestoda, including Spathebothriidea, filiform microtriches have been observed (Charles and Orr 1968, Burt and Sanderman 1974, Hayunga and Mackiewicz 1975, Richards and Arme 1981, Kuperman 1988, Davydov et al 1997, Poddubnaya et al 2006.…”

“…Filiform microtriches, present in all major cestode groups, are considered to be an ancestral type and they can vary considerably in size (Palm et al 2000, Palm 2004). During the Sixth International Workshop on Cestode Systematics and Phylogeny (Smolenice, Slovakia, 15-20 June 2008), participants proposed to classify filiform microtriches to three main types depending on their length: papillate (short), aciculate and capillate (long) (L. Chervy -in preparation).…”

“…Comparatively long or longer, slender microtriches (7-50 µm long) as those found in C. truncatus have been described from the tegument of plerocercoids of Diphyllobothrium dendriticum, D. ditremum and D. vogeli (Diphyllobothriidea) and also on the proximal end of the scolex peduncle of many larval trypanorhynchs (Andersen 1975, Palm 2004. Elongate or hair-like filiform microtriches have also been reported on the scolices of some adult trypanorhynchs (Pseudolacistorhynchus noodti, Poecilancistrum caryophyllum), diphyllideans (Macrobothridium euterpes and M. syrtensis) and tetraphyllideans (Paraorygmatobothrium janineae, Paraorygmatobothrium kirstenae and Ruhnkecestus latipi) (Palm et al 2000, Neifar et al 2001, Caira and Durkin 2006, Ruhnke et al 2006.…”

Abstract. The scolex surface of the mature spathebothriidean Cyathocephalus truncatus (Pallas, 1781), a parasite of the brown trout Salmo trutta fario L., was studied using scanning and transmission electron microscopy. A particular attention was paid to microtriches, unique structure on the surface of the Cestoda. The scolex of C. truncatus is covered with two types of filiform microtriches (filitriches): aciculate (≈ 3 µm long) and capillate (≈ 10 µm long). Capillate microtriches, which have never been reported in any other spathebothriideans, are described for the first time using transmission electron microscopy. The tegument covered with filiform microtriches only (no spiniform microtriches are present) is typical of cestode groups supposed to be the most basal, e.g., Gyrocotylidea, Spathebothriidea, and Caryophyllidea.

Trypanorhynch cestodes are parasites of rays and sharks and occupy a special position in the class Cestoda, characterizing their highly specialized attachment apparatus. The phylogeny of the Trypanorhyncha is not fully understood and in fact comprises two independent lineages: Trypanobatoida and Trypanoselachoida. The ultrastructure of the adult tapeworms ofGrillotia erinaceusfrom the spiral valve ofRaja clavatacaught in the coastal waters of the Black Sea has been studied by transmission and scanning electron microscopy. New data concerning the polymorphism of microtriches, the rhyncheal system, and rhynchocoel are presented with illustrations.
