Fig. 3. BEAST ultrametric tree of buffalo leeches genus Hirudinaria. Leeches from southern Thailand are highlighted in bold. Numbers on nodes are bootstrap values from ML tree generated by IQ-TREE, Bayesian posterior probability from BI tree generated by MrBayes, and from ultrametric tree generated by BEAST, respectively. Black bars indicate morphological identification (MORPHO) and delineated OTUs suggested by four species delimitation approaches (GMYC, bPTP, BIN, and ABGD). Grey bars indicate samples that were not available for morphological identification.

Fig. 4 in Predation of Oysters Using an Autonomic Pharynx in the Oyster Leech sp. (Polycladida: Stylochidae).

Fig. 4. The three predatory processes for Cryptostylochus sp. on Portuguese oysters (Magallana angulata). A, Attack period: flatworms extend their pharynx into the oyster from the shell opening for 4 to 8 hours and some autonomic pharynges are formed. B, Invasion period: the stylochid flatworms crawl into the shell after the oyster cannot resist and the oyster gradually loses its ability to close its shell. C, Ingestion period: the flatworm wraps the entire oyster flesh and separates it from the shell. f, flatworm; o, oyster; p, protruding pharynx.

Fig. 5. Cumulative shell valve openings and closures frequency for Portuguese oysters (Magallana angulata) and Asian hard clams (Meretrix lusoria) during the attack period by Cryptostylochus sp. (each test used five each of oysters and clams).

Fig. 2 in Predation of Oysters Using an Autonomic Pharynx in the Oyster Leech sp. (Polycladida: Stylochidae).

Fig. 2. Illustration of the collection of autonomic pharynges from Cryptostylochus sp. The flatworm is flipped over with its ventral surface facing upward. The highly ruffled pharynx is everted under stimulation by pressing the ventral surface with a paintbrush. The pharynx extends and spontaneously breaks into pieces of autonomic pharynges, which are collected by tweezers.

Fig. 1 in Predation of Oysters Using an Autonomic Pharynx in the Oyster Leech sp. (Polycladida: Stylochidae).

Fig. 1. Cryptostylochus sp. A, Dorsal view and B, ventral view. The pharynx is large and highly ruffled. The mouth is in the center of the pharynx ventrally. The head is on the right side. t, tentacles; p, pharynx; m, mouth.

Fig. 6. A in Predation of Oysters Using an Autonomic Pharynx in the Oyster Leech sp. (Polycladida: Stylochidae).

Fig. 6. A, Protruding pharynx of Cryptostylochus sp. and the autonomic pharynx shown by arrows. B, Collected autonomic pharynx placed on the surface of a clam shell to easily record and analyze the video results. Using the time-lapse video, we found that some autonomic pharynges slowly crawled around for roughly 10 hours before losing mobility. ap, autonomic pharynx; p, protruding pharynx.

Fig. 3 in Field and experimental evidence of a new caiman trypanosome species closely phylogenetically related to fish trypanosomes and transmitted by leeches

Fig. 3. Proposed life cycle of T. clandestinus and its developmental and morphological features in caiman blood and leeches. Giemsa-stained blood smears showed blood trypomastigotes of experimentally-infected Caiman yacare, and epi- and trypomastigotes found in the gut of one leech of the genus Haementeria sp. collected in the mouth of a wild Cayman yacare captured in the Pantanal wetland of Brazil. The caiman and the leech trypanosomes were molecularly identified as T. clandestinus. (a‾c) epimastigotes; (b) epimastigote dividing by binary fission; (d, g) short trypomastigote; (e,f) long and thin trypomastigotes. Arrow points to the long and thin posterior extremity of very long and slender trypomastigotes. K, kinetoplast; N, nucleus; F, flagellum.

Fig. 2 in Field and experimental evidence of a new caiman trypanosome species closely phylogenetically related to fish trypanosomes and transmitted by leeches

Fig. 2. Phylogenetic tree (ML) based on gGAPDH sequences showing the Terrestrial and Aquatic clades of Trypanosoma and the positioning of T. clandestinus. The Crocodilian clade, which is formed by T. terena, T. ralphi, T. gray and Cay03 nests in the Terrestrial Clade whereas the Clandestinus clade comprising T. clandestinus nests in Aquatic clade. Typanosomatid genera other than Trypanosoma were used as outgroups in the phylogenetic trees (608 characters, Ln = —7611.897017). Numbers at nodes are bootstrap support (P/ML)>50% and Bayesian posterior probability>0.25 derived from 500 replicates.

Fig. 1 in Field and experimental evidence of a new caiman trypanosome species closely phylogenetically related to fish trypanosomes and transmitted by leeches

Fig. 1. Geographical origin of crocodilian trypanosomes included in the V7V8 SSU rRNA dendrogram inferred to compare the barcode sequences between the new and known trypanosomes from crocodilians and other species of aquatic and semi aquatic hosts. The clade comprising T. clandestinus n. sp. nested into the Aquatic clade closely related to fish trypanosomes whereas sequences of the other new species formed the clade Cay03, which clustered with T. terena, T. grayi and T. ralphi in the Crocodilian Terrestrial clade. The host species and geographic origin and Genbank accession numbers of sequences from the crocodilian trypanosomes are shown in Table 1. Numbers at nodes are bootstrap support values>50% (P/ML) derived from 500 replicates.

Fig. 3 in Batracobdella leeches, environmental features and Hydromantes salamanders

Fig. 3. Distribution of studied sites for Hydromantes flavus. The map shows the altitude levels of the studied area; the polygon represents the whole distribution area of H. flavus. Yellow circles indicate sites where B. algira was not observed, while green squares indicate sites in which the leech was present. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
