Abstract
There are only five studies on tintinnids of the Philippines. We present a checklist of tintinnids (Ciliophora, Oligotrichea) from Masinloc-Oyon Bay, Province of Zambales, West Philippine Sea. Masinloc-Oyon Bay is a unique in having both marine protected areas and a coal-fired thermal power plant within the same bay. Field sampling was performed in July 2017, which recorded 10 species belonging to one order, six families, and seven genera. Station 1 inside the power plant’s outfall had the lowest diversity, whereas the stations within marine protected areas had a relatively higher species diversity index. Our new data are the first records of tintinnid species in Masinloc-Oyon Bay. These records add to the regional checklist of the Philippine Sea.
Highlights
Microzooplanktonic tintinnids are the most common and widespread group of marine ciliates (Kato and Taniguchi 1993)

Summary
Microzooplanktonic tintinnids are the most common and widespread group of marine ciliates (Kato and Taniguchi 1993). They are identifiable organisms due to their recognizable lorica morphology. Tintinnids are potential bioindicators of water quality and water masses by utilizing their biogeographic classification. These planktonic ciliates have been used by researchers to assess the source of eutrophication and pollution in aquatic environments (Lee and Kim 2010; Kim et al 2012). These planktonic ciliates have been used by researchers to assess the source of eutrophication and pollution in aquatic environments (Lee and Kim 2010; Kim et al 2012). Kamiyama and Tsujino (1996) have shown that abundance of tintinnids is correlated to temperature. Pierce and Turner (1993) categorized tintinnids into biogeographic groups namely: cosmopolitan, neritic, warm, tropical Pacific, boreal, and austral species
