\u00a0Description And Feeding Habits<\/h3>\n

\u00a0 \u00a0 \u00a0 \u00a0A dinoflagellate cell globular, polygonal, or extended into apical and <\/span>antapical<\/span> horns; cingulum more or less median; thecal plates usually thick and often strongly ornamented; heterotrophic pallium feeding; very important in marine plankton. (Refs <\/span>Balech<\/span> 1988; Jacobson & Anderson 1986, 1992). They typically are between 220- 300 Micro-meters and 150 Micro-meters wide at full size. Interestingly enough their color depends on their diet. Their typical habitats are coastal and oceanic environments. They range from warm temperate to tropical waters. They typically are in waters that range from 5- 23 degrees C and 31- 36 PPM in salinity. The <\/span>protoperidinium<\/span> reproduces both sexually and asexually (<\/span>Guiry<\/span>, Michael D., 2015).<\/span><\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0 \u00a0This <\/span>mi<\/span>crozoo\"NAPProtop\"plankton<\/span> <\/span>Protoperidinium<\/span> <\/span>p<\/span>ellucidum ( tentative ID)<\/span> is a pallium feeder, and captures to digest phytopl<\/span>ankton cells (Jacobson and Ander<\/span>son<\/span>,<\/span> 1986). They feed by extruding their cytoplasm out of their theca in the form of a pseudopodium and engulfing their prey. After eating their prey it retracts it<\/span>self back in <\/span>(<\/span>Jackobson<\/span> and Anderson, 1986<\/span>)<\/span>. <\/span>Phytoplankton cells are less abundant than smaller-sized\u00a0<\/span>cells so they search for specific prey. After passing a n<\/span>earby potential food item, the <\/span>P<\/span>rotoperdinium<\/span> circles around the source several times without even making contact with it. This behavior suggests there is some type of chemoreception used to recognize the potential food item (Edward J.\u00a0<\/span>Buskey<\/span>, 1997).<\/span><\/p>\n
