The Geoemydidae are one of the largest and most diverse families in the order Testudines (turtles), with about 70 species. The family includes the Eurasian pond and river turtles and Neotropical wood turtles. Members of this family are commonly called Leaf turtle.
The giant Asian pond turtle inhabits rivers, streams, marshes, and rice paddies from estuarine lowlands to moderate altitudes throughout Cambodia and Vietnam and in parts of Laos, Malaysia, Myanmar and Thailand.
Opisthorchis viverrini, common name Southeast Asian liver fluke, is a food-borne trematode parasite from the family Opisthorchiidae that infects the bile duct. People are infected after eating raw or undercooked fish. Infection with the parasite is called opisthorchiasis. O. viverrini infection also increases the risk of cholangiocarcinoma, a cancer of the bile ducts.
Rhynchobdellida, the jawless leeches or freshwater leeches, are an order of aquatic leeches. Despite the common name "freshwater leeches", species are found in both sea and fresh water. They are defined by the presence of a protrusible proboscis instead of jaws, and having colourless blood. They move by "inchworming" and are found worldwide. The order contains 110 species, divided into 41 genera and three families. Members of the order range widely in length, usually between 7 and 40 mm. They are hermaphrodite. The order is not monophyletic.
The keeled box turtle is a species of turtle in the family Geoemydidae. The species is endemic to Asia.
The Asian leaf turtle is a species of turtle found in Southeast Asia. They are quite common in the pet trade; their carapaces resemble that of a Cuora amboinensis hybrid.
The yellow-headed temple turtle is a large species of turtle in the family Geoemydidae. The species is native to Southeast Asia.
Glossiphoniidae are a family of freshwater proboscis-bearing leeches. These leeches are generally flattened, and have a poorly defined anterior sucker. Most suck the blood of freshwater vertebrates like amphibians, crocodilians and aquatic turtles, but some feed on invertebrates like oligochaetes and freshwater snails instead. Although they prefer other hosts, blood-feeding species will opportunistically feed from humans.
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels.
Cyclemys is a genus of freshwater turtles, commonly referred to as Asian leaf turtles, from the family Geoemydidae. The genus occurs throughout Southeast and South Asia, and currently contains seven species.
Echinostoma revolutum is a trematode parasites, of which the adults can infect birds and mammals, including humans. In humans, it causes echinostomiasis.
Cyclemys enigmatica, also known as the enigmatic leaf turtle, is a species of Asian leaf turtle. It is found in the Greater Sunda Islands and the Malay Peninsula.
Turtle leeches are a genus, Ozobranchus, of leeches (Hirudinea) that feed exclusively on the blood of turtles. Only two species – Ozobranchus margoi and Ozobranchus branchiatus – are found in the Atlantic coast of the United States and the Gulf of Mexico. Little is known about these leeches due to difficulties in studying their sea turtle hosts.
The Malayan snail-eating turtle is a species of turtle in Malayemys genus of the family Geoemydidae.
Erpobdella octoculata is a freshwater leech in the Erpobdellidae family. This species can be found in Europe, the Mediterranean, and the Middle East.
The Khorat snail-eating turtle is a species of turtle in the family Geoemydidae. They are freshwater turtles from Khorat Plateau in Thailand but were found for the first time in Udon Thani, Thailand.
Ozobranchus branchiatus is a species of leech in the family Ozobranchidae. It is found in the Atlantic Ocean and is a permanent parasite of sea turtles, mostly the green sea turtle.
Placobdelloides is a genus of glossophoniid leeches.
The Faculty of Science, Kasetsart University is the school of science of Kasetsart University in Bangkok, Thailand. The Faculty offers undergraduate, master's, and doctoral programs. Faculty of Science, Kasetsart University was ranked as top 500 in the world for Biological Sciences, Chemistry, and Computer Science & Information Systems by QS World University Rankings by Subject. It has consistently been regarded as one of the top science schools in Thailand, often recognized for faculty research, academic teaching, and admission selectivity. Notable members of the faculty include celebrated scientists Princess Chulabhorn, a Thai princess who was awarded the UNESCO Albert Einstein medal.
Myzobdella lugubris, the crab leech, is a species of jawless leech widespread in North America, especially in central and Eastern Canada. It is an ectoparasite of fish and crustaceans, and is responsible for several dangerous conditions in fish, including lesions infected by bacteria and fungi and possibly viral hemorrhagic septicemia. It lays its egg capsules on crabs and possible other arthropods, which then disperse the eggs.
