Article
Blood flukes of the family Spirorchiidae Stunkard, 1921 are significant pathogens of marine turtles, both in the wild and in captivity. Despite causing considerable disease and mortality, little is known about the life cycles of marine species, with just four reports globally. No complete life cycle has been elucidated for any named species of mari...
Article
Trematodes are the richest class of platyhelminths in the marine environment, infecting all classes of marine vertebrates as sexual adults and many phyla of marine invertebrates as part of their life cycles. Despite the cryptic nature of their existence (almost all marine trematodes are internal parasites), they have been the focus of study for alm...
Article
Molecular data have transformed approaches to trematode taxonomy by providing objective evidence for the delineation of species. However, although the data are objective, the interpretation of these data regarding species boundaries is subjective, especially when different markers conflict. Conserved markers can lead to an underestimation of richne...
Article
Stable isotope analyses of carbon and nitrogen (δ13C and δ15N) are useful for elucidating consumer relationships of free-living organisms, as carbon isotopes indicate dietary carbon sources and incremental increases in nitrogen isotopic enrichment are correlated with increases in trophic position. However, host-parasite relationships are more diffi...
Article
Novel multi-locus sequence data were used to assess the molecular phylogenetic relationships of fish blood flukes showing similarity to the genus Cardicola Short, 1953 (Trematoda: Aporocotylidae). Analyses of three ribosomal (ITS2, 28S & 18S) subregions and one mitochondrial (cox1) DNA subregion shows that the hitherto-monophyletic clade formed by...
Article
The trematode superfamily Monorchioidea comprises three families of teleost parasites: the Monorchiidae Odhner, 1911, Lissorchiidae Magath, 1917, and Deropristidae Cable & Hunninen, 1942. All presently known lissorchiid and deropristid life cycles have gastropods as first intermediate hosts, whereas those of monorchiids involve bivalves. Here, we r...
Article
The digenetic trematode family Gorgocephalidae comprises just a few species, and the literature devoted to the lineage consists of only a handful of reports. With one exception, all reports have been based on material collected in the Indo-West Pacific, an expansive marine ecoregion stretching from the east coast of Africa to Easter Island, Hawaii...

Three species of jellyfish were captured within Port Phillip Bay, Australia, and three species of fish that feed on jellyfish were obtained from Moreton Bay (Queensland) and Port Phillip Bay and Portland (Victoria). Th...
Article
Lasiotocus Looss, 1907 is the largest genus within the Monorchiidae Odhner, 1911, with 52 species currently considered valid. Species belonging to this genus exhibit wide morphological variation and it is likely that many of them belong in other genera; however, testing the validity of the group has been hampered by a lack of molecular sequence dat...
Article
Fish blood flukes (Digenea: Aporocotylidae) are important pathogens of fishes in aquaculture. Severe infections have been associated with mass mortality events in cultured marine species of teleosts in Australia, Asia and Europe, leading to significant socio-economic losses. Here we review recent advances towards understanding the biology and ecolo...

... Didymozoid life cycle has not been fully investigated in natural or experimental conditions, and therefore, still poorly understood. However, recently, the first evidence, using molecular data matching a didymozoid life cycle with three hosts as follows: didymozoid species use a bivalve as first intermediate host, a benthivorous fish as intermediate host (apparently the third host), and large piscivorous fish as its definitive host (Louvard et al. 2022). Thus, Louvard et al. (2022) study provides new evidence of an alternative life pathway in the life cycle of didymozoids because previously was conceptualized as follows: the first intermediate hosts are gastropods, the second intermediate hosts are small crustaceans, possibly copepods (Madhavi 1968), the third intermediate or paratenic hosts are zooplanktonic invertebrates and small fishes, and the definitive hosts are large predatory fishes (Nikolaeva 1965;Køie and Lester 1985;Al-Bassel and Ohaida 2006). ...
... Annual monitoring of helminth fauna of large aquatic ecosystems as the Vazuz Reservoir in connection with the intensively developing ecotourism and human-induced impact, in general, is necessary and allows the prediction of further changes in the parasitological situation. For the complete picture of the helminthiasis epizootic situation of helminthiasis, a set of studies is necessary, aimed at the study of all groups of animals involved in the life cycles of parasitic worms (Cribb et al. 2022;Kuzmina 2017;Laidemitt et al. 2016;Salgado-Maldonado et al. 2020). The study aims to monitor the helminth fauna of teleost fish in the Tver region. ...
... However, genetic data for all three sequenced regions indicate that there are two distinct, morphologically cryptic lineages in complete sympatry (same fish individual). Wee et al. [27] reported two similarly cryptic species that correspond to Helicometroides longicollis Yamaguti, 1934. That study extended the species recognition model proposed by Bray et al. [28] to account for circumstances in which cryptic morphology is combined with sympatric lineages (including the same host individual) in both recombinant (e.g. ...
... Aporocotylids infecting fishes of the Tetraodontidae (pufferfishes) were reported by Yong and Cribb [1], Yong et al. [2], and Yong et al. [3], those infecting fishes of the Labridae (wrasses), Mullidae (goatfishes) and Siganidae (rabbitfishes) by Cutmore et al. [4], those infecting fishes of the Lutjanidae (snappers) and Scombridae (tunas and mackerels) by Nolan et al. [5], and a species widely infecting members of the Chaetodontidae (butterflyfishes) was reported by Yong et al. [6]; all of these fish families are known to host blood flukes elsewhere in the Pacific. New genera and species were described from several reef fish families not previously known to host blood flukes, from the Apogonidae (cardinalfishes), Balistidae (triggerfishes), Chanidae (milkfishes), Holocentridae (squirrelfishes), Pomacentridae (damselfishes), and Ostraciidae (boxfishes) (see [3,7,[8][9][10]). This study reports further collections of aporocotylids from the tropical western Pacific, from the Great Barrier Reef, southern Japan, and French Polynesia, including the description of a new genus and two new species. ...
... Infections with intravascular digenean trematodes of the Spirorchiidae family (spirorchiidoses) can be associated with clinical disease and are of great conservation concern both in marine and freshwater turtles due to their impact on endangered and vulnerable species worldwide (Chapman et al., , 2019Iglesias et al., 2015). Vermetid, pulmonated, prosobranch and fissurelid gastropods (Corner et al., 2021;Cribb et al., 2017;Holliman et al., 1971;Pieper, 1953;Stacy et al., 2010;Turner and Corkum, 1977;Wall, 1940Wall, , 1941, as well as polychaete worms (de Buron et al., 2018) have been found to act as intermediate hosts for different species of marine and freshwater spirorchiid blood flukes. The infection of the definitive hosts is thought to occur following direct skin penetration by fork-tailed cercariae (Chapman et al., 2019;Holliman et al., 1971). ...
... The inventory is near complete for some taxa like birds and mammals, whereas it is far from it for most invertebrate phyla. The latter is certainly true for parasitic organisms, as evidenced by multiple assessments of known versus unknown parasite biodiversity for various regional parasite faunas [2][3][4] or parasite taxonomic groups [5,6], as well as across all taxa on a global scale [7,8]. Yet, more new parasite species are being found and described per year than ever before [8,9], indicating that parasite discovery and taxonomy are active research areas not lacking in new material. ...
... However, it was demonstrated that this ratio changes allometrically during the life span, at least for Aporocotyle simplex, and the number of testis is also a taxonomic character of questionable relevance because the number is highly variable and the degeneration of testis in larger specimens is well documented [29]. Our results strongly suggest that the described species of Aporocotyle from South American hakes belong to a single species, Aporocotyle argentinensis, and are a new evidence of the usefulness of molecular tools to obtain the correct species diagnosis in digenean parasites [30]. ...
... A similarly low level of variation was reported for L. cirripectis Bray, Cutmore & Cribb, 2018(see Bray et al., 2018b. Several trematode species also show little to no differences in cox1 sequences from sites at least as distant as Heron and Lizard Islands: one species of the Aporocotylidae (see Cutmore et al., 2021), two species of the Fellodistomidae Nicoll, 1909 (see Cribb et al., 2021), five species of the Lepocreadiidae (see Bray et al., 2018b;2022) and three species of the Monorchiidae (see McNamara et al., 2014). These varying patterns of intraspecific genetic variation suggest that trematodes are likely differentially affected by geographical or host-related factors which either limit or benefit their dispersal; however, no synthesis of explanation has emerged so far. ...
... Furthermore, these worms are invariably yellow to orange in life, suggesting sequestration of algal pigments (the name of the type-species even alludes to this colouration: aureum =gold; en = in; enterum = intestine). These observations, coupled with the results of stable isotope analyses of a species of Enenterum and its host, K. bigibbus, led Huston et al. (2021a) to speculate that enenterids derive nutrition, at least partially, from the products of microbially digested algal cells from the kyphosid intestine. Potentially, the variation in oral sucker lobation among enenterids might be driven by opportunity to exploit the various algal or microbial food sources available in kyphosid intestines. ...
... Significant substitution saturation and significant non-stationarity were both detected for codon 3 in the Cardicola (sensu lato) dataset, and thus downstream analyses used only codons 1 + 2. Unrooted Neighbour joining analyses were conducted using MEGA 11 for each of the cox1 and ITS2 datasets to explore species boundaries, with the following parameters "Model/Method = No. of differences", "Substitutions to Include = d: Transitions + Transversions", "Rates among Sites = Gamma Distributed" and "Gaps/Missing Data Treatment = Pairwise deletion". Nodal [39,86] support was estimated by performing 10,000 bootstrap replicates. Pairwise differences were estimated for each dataset using the following conditions: "Variance Estimation Method = None", "Model/Method = No. of differences" and "Substitutions to Include = d: Transitions + Transversions" and "Gaps/Missing Data Treatment = Pairwise deletion". ...
