Parasite of the Day: Euglenaformis parasitica
http://dailyparasite.blogspot.com/2023/12/euglenaformis-parasitica.html

"#Euglena and its kin are mostly free-living, photosynthesizing when the sun's out, absorbing organic matter from the environment when it's dark.

These #euglenids were found parasitising #ostracods & #flatworms in a rice field in #Ibaraki, #Japan."
