Videonummer 11944191
Vampyrella feeding on algae. Time-lapse light microscopy footage of a Vampyrella lateritia trophozoite (centre) attached to and feeding on a strand of Spirogyra algae (tubular). Vampyrella is a unicellular micro-organism sometimes described as a 'vampire amoeba'. It attacks other microscopic organisms, such as algae, and penetrates their cell walls and extracts the contents (green). The complete process of cell wall penetration, suction and extraction is shown in this clip. Vampyrella are found in aquatic freshwater environments, with other vampyrellid species found in soil and in the sea. The speed of this footage has been increased to twenty times normal.
