The green eye animal ( Euglena viridis ) is a type of protist from the genus of the eye animal ( Euglena ).

features

Euglena viridis is 40 to 80 micrometers long and 12 to 20 micrometers wide. The cells are spindle-shaped, they move quickly and jerkily. The scourge is as long as the body.

The ligamentous chloroplasts radiate out from a centrally located pyrenoid and are surrounded by a shell of paramylon grains. Under poor living conditions they are rounded in shape and act like individual, disc-shaped chloroplasts. Small, rounded bodies produce copious amounts of mucus. Palmellae and cysts often form on the muddy subsoil at pond edges .

ecology

Euglena viridis is a common freshwater species in polluted habitats; it is often found on farms in the form of " algal blooms ". It also occurs in ponds, manure puddles and muddy bank zones.

Although the green eye animal does photosynthesis , it can also feed on organic substances heterotrophically .
