What are the characteristic features of Euglenoids?

Explanation

Some characteristic features of Euglenoids are as follows.
`implies` Euglenoids (such as Euglena) are unicellular protists commonly found in fresh water.
`implies` Instead of cell wall, a protein-rich cell membrane known as pellicle is present.
`implies` They bear two flagella on the anterior end of the body.
`implies` A small light sensitive eye spot is present.
`implies` 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.
`implies` They have both plant and animal-like features, which makes them difficult to classify
