A *euglenophyte* is a type of single-celled eukaryotic alga, belonging to the phylum Euglenophyta. These organisms are characterized by their flagella and their ability to perform photosynthesis. Most *euglenophytes* are found in freshwater environments. Some can also survive in brackish or marine waters. They are unique due to their flexible cell structure and the presence of an eyespot. Think of them as tiny, adaptable algae that use light to make food. They demonstrate the variety of life in the microbial world.
