Common co-existing organism Euplotes (Ciliate, Protozoa) well often observed in the rotifer mass culture tank of marine fish larval rearing stations. Ciliate protozoa (Euplotes) competed to condensed food (micoralgae, Nannochloropsis oculata) with rotifer (Brachionus rotundiformis). As results, rotifer density was rapidly decrease, and what is more, the rotifer was wiped out by dominant bacteria species at that time.

In order to investigate the population of rumen ciliate protozoa and pH of rumen contents of Korean native goat, 20 goats, slaughtered at Jeonju private abattoir, were selected from Februry to April 1979. The results obtained in this work were summarized

The morphology and ecology of the marine hypotrichous ciliate, Oxytricha saltans (Cohn, 1866) Kahl, 1932 collected from shrimp culturing pond of Qingdao (Tsingtao, 36$^{\circ}$08'N : 120$^{\circ}$43'E) , P.R. China were investigated. collected samples were observed directly and we also observed cultured ones and stained specimens. In relation to this species were described the morphology and infraciliature in detail using protargol method, presented a new diagnosis and discussed some synonyms and the related species, Actinotricha saltans sensu Dragesco, 1963.

Eight samples, collected from six moss-covered soil and two freshwater samples, were examined to determine ciliate diversity in Korea. Based on the morphology of living and stained specimens, thirteen ciliate species, previously unrecorded in Korea, were identified. These specimens were classified to four classes, seven orders, ten families, and twelve genera. Of these genera, the following six were first records in Korea: Bresslauides, Dexiotricha, Glaucoma, Paragastrostyla, Sathrophilus, and Trithigmostoma. Here, we provide a brief description of the morphology of these 13 taxa along with microphotographs and notes.

We collected ciliates from terrestrial and aquatic habitats in Korea. Morphology was examined based on observations of both living and stained specimens. As a result of the observations, we found 24 previously unrecorded ciliate species to Korea. The morphology of these species are briefly described here: Tracheloraphis dracontoides, Condylostoma arenarium, Aspidisca steini, Australocirrus aspoecki, Sterkiella tricirrata, Stylonychia lemnae, Wallackia bujoreani, Bakuella marina, Anteholosticha sigmoidea, Holosticha pullaster, Urostyla grandis grandis, Chaenea vorax, Enchelys gasterosteus, Phialina salinarum, Mesodinium pulex, Aegyria oliva, Bryometopus pseudochilodon, Pinacocoleps tesselatus, Urozona buetschlii, Colpidium colpoda, Campanella umbellaria, Pseudovorticella difficilis, Zoothamnium parahiketes and Z. plumula. Among these 24 ciliates, S. tricirrata and U. grandis grandis were studied based on both the morphology and the morphogenesis.

After the first record of a Korean ciliate in 1931, more than 130 papers have been published describing Korean ciliates. Of these records, the years 1997, 2012, and 2016 include milestone publications in Korea. Even though the publications provide summarized data about Korean ciliates with relevant literature citations, these publications included two nomenclatural errors, two misspellings, and one misidentification; nine species were transferred to other genera. Furthermore, the type specimens deposited in the laboratory of Prof. Joong Ki Choi (Inha University, Korea) were transferred to the National Marine Biodiversity Institute of Korea (MABIK) because of his retirement. Here, we provide an updated list of 331 Korean species described by 2016 and present information about the type specimens. We also and address the aforementioned problems with bringing together scattered data related to ciliate lists.

We collected ciliate species from diverse habitats (brackish water, marine water, and terrestrial ecosystems) composed of estuarine, coast, and moss samples during 2017-2018 in Korea. The morphology and infraciliature of these species were examined and identified based on the observations of living cells and protargol impregnated specimens. Of the ciliates we identified, we described eight unrecorded species in Korea as followings: class Heterotrichea - Condylostoma vorax, Peritromus kahli; class Protocruziea - Protocruzia labiata; class Spirotrichea - Hemiamphisiella granulifera; class Litostomatea - Loxophyllum chinense; class Phyllopharyngea - Trochilioides recta; and class Oligohymenophorea -Cohnilembus verminus, Uronemella filificum. Among them, Protocruzia labiata is a poorly known species. In this paper, we provide the improved diagnoses and brief descriptions of the species with their microphotographs. The taxonomic classifications of the eight species are summarized as six classes, eight orders, five families, and eight genera. These voucher slides with protargol impregnated specimens have been deposited in the National Institutes.

Ciliates are unicellular eukaryotes and one of the most abundant and speciose protistan groups. However, their diversity is underestimated, and many new species are waiting for our discovery. During several field surveys conducted from 2018 to 2021 to document indigenous Korean ciliates, 10 unrecorded ciliate species were collected and investigated from freshwater, marine, and semiterrestrial habitats. The morphology of these species was studied based on observation of living and protargol-stained specimens. These species belong to five classes as follows: 1) class Heterotrichea - Peritromus faurei; 2) class Spirotrichea - Heterotachysoma dragescoi, Pseudokeronopsis parasongi, and Certesia quadrinucleata; 3) class Nassophorea - Chilodontopsis depressa; 4) class Prostomatea - Plagiocampa rouxi and Urotricha furcata; and 5) class Oligohymenophorea - Metanophrys similis, Uronema gallicum, and Protocyclidium citrullus. Also, we provide a brief diagnosis, photomicrographs, and information of the locality for each species. Further, we compare each species with the most recent description and with similar congeners.
