Vampyrella feeding on algae, time-lapse

Référence de la vidéo 11944161
Vampyrella feeding on algae. Time-lapse light microscopy footage of a Vampyrella lateritia trophozoite (round) attaching 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). This violent and destructive extraction is shown halfway through the clip. Vampyrella are found in aquatic freshwater environments, with other vampyrellid species found in soil and in the sea. This sample is from pond water. The speed of this footage has been increased to four times normal.
