Most likely your creature is an Euglena, a creature that possesses both animal and plant characteristics.
A characteristic of plants is that they synthesize their own food (the process is known as autotrophism) through photosynthesis, a process carried out by the chloroplasts it contains. Creatures that must consume food are described as heterotrophic, which is a property associated with animals.
The Euglena are unique, possessing their own phylum, because they have both plant and animal characteristics, they are both autotrophic and heterotrophic, contingent upon the conditions they find themselves in. Additionally, They have a grouping of cells (the eyespot) which are light-sensitive, so they can move towards the light to photosynthesize, and a flagellum, the whip like structure they use to move through the water.
