There are very complete answers in the encyclopedia, if you are afraid of trouble, I will help you copy it for you:
It's paramecium, not grass cover: ciliates. The body is cylindrical, the front end is rounded, the middle and back parts are wide, and the back end is pointed, like an upside-down straw sandal, so it is called a paramecium.
He is covered in cilia that he can use for movement. There is a small groove on one side of the body that extends diagonally to the waist, called the "mouth groove". There is a mouth at the bottom of the mouth and cilia in the groove of the mouth, which can puff up a water vortex and feed on bacteria and other organic matter in the water.
Prefer to live in ponds, ditches, depressions, etc., which are rich in organic matter. Most paramecium are fully motile nutrients, but the exception is paramecium, which contains symbiotic green algae, which can use nitrogenous waste excreted by animals as inorganic salts** to survive by making organic matter through plant-based photosynthesis (which is a plant-based nutrition. Paramecium can live in anoxic or anaerobic environments and is extremely stain-resistant.

Grass overworms live in unpolluted freshwater areas.
-
Grass covers live in gently shallow water.

Paramecium is a small, cylindrical protozoan that is made up of only one cell and is a unicellular animal that is hermaphroditic. The most common is Cercocerium paramecium. The body length is only 180 to 280 microns.
It and amoeba have the shortest lifespan, measured in hours, and the lifespan is about a day and night. (Paramecium can live for more than five days and nights.) It is called paramecium because its body shape looks like an upside-down straw sole from a flat angle, and it requires a microscope to observe it closely.

It has the shortest lifespan with amoebae, measured in hours, and the lifespan is about a day and night. It is called paramecium because its body shape looks like an upside-down straw sole from a flat perspective.
Prefer to live in ponds, ditches, depressions, etc., which are rich in organic matter. Most paramecium are fully motile vegetative, with the exception of paramecium, which contains symbiotic green algae, which can use nitrogenous waste excreted by animals to increase hunger as inorganic salts** and survive by making organic matter through plant-based photosynthesis [1] (which is a plant-based nutrition. Paramecium can live in anoxic or anaerobic environments and is extremely stain-resistant.
Cordyceps sinensis is a fungus, not a worm or a grass, this fungus is called Cordyceps fungus, which is mainly parasitic in the larvae of bat moths, absorbing the nutrients of the larvae for growth and development.
