Previously belonging to Kingdom Protista but have since been broken up into different kingdoms ("What Are Dinoflagellates?"). Approximately 4500 species have been described and organized into 550 genera. Almost three quarters of the genera and more than half of the species are fossil. Around 1700 are marine and about 220 are living in freshwater. Their specie growth is

Further inspection of the specific microbes involved caused researchers to speculate that Bacteroides species of the Bacteriodetes phylum prevented further weight gain in obese mice upon transfer from the lean mice. Unfortunately‚ this idea was proven false upon placing obese mice and lean mice in the same habitat‚ which resulted in a lack of reduced weight gain in the obese mice. In
