What are the characteristic features of Euglenoids?

Some characteristic features of Euglenoids are as follows.

  • Euglenoids (such as Euglena) are unicellular protists commonly found in fresh water.

  • Instead of cell wall, a protein-rich cell membrane known as pellicle is present.

  • They bear two flagella on the anterior end of the body.

  • A small light sensitive eye spot is present.

  • They contain photosynthetic pigments such as chlorophyll and can thus prepare their own food. However, in absence of light, they behave similar to heterotrophs by capturing other small aquatic organisms.

  • They have both plant and animal-like features, which makes them difficult to classify.
