Thraustochytrids are non- photosynthetic marine protests, belonging to chromists. They display an obligate sodium requirement, so they are widely distributing in the ocean, estuary, inland salt lakes and the mangroves. The thalli of thraustrids are similar to the monocentric chytrids. Thraustochytrids have biflagellate zoospores and non-flagellate aplanospores. They are saprophytic on algae and phanerogamic detritus and parasitic on invertebrate. In the asexual reproduction, the thallus includes the sporangium and ectoplasmic net. So far, no sexual reproduction have been documented in any thraustochytrids.
Thraustochytrids are isolated from the soil and water samples collected in the north coast of Taiwain by using pine pollen grains(Pinus taiwainensis). All isolates were successively transferred by streaking on the KMV agar medium containing antibiotics until the cultures were purified. Then transferred the thraustochytrids on the KMV agar medium and in pollen seawater. In such culture conditions, observation and discription of their morphological characteristics were made.
Totally, three genera and nine species are successfully examined and identified namely : five species of Thraustochytrium : T. motivum 、T. antarcticum 、T. proliferum 、T. kinnei 、T. aggregatum；two species of Ulkenia : U. visurgensis 、 U. radiata ；two species of Schizochytrium ：S. octosporum S. mangrovei. Among them, T. antarctium、T. kinnei 、U. visurgensis、U. radiata、S. octosporum、S. mangrove are described as new records to Taiwain.
