This final week my microaquarium seemed very active. Like last time I did not see as many cyclops as I did at the beginning, but many halteria and other fast moving aquatic creatures were present. This time I collected an image of a Peranema. Peranemas have an oblong shape an are easily identified by the long flagella at the end of their body.
Peranema
feed by engulfing euglenids. Their thick flagellum can be used to whip through the water and rapidly change course, or just the tip can be used be used to move the cell smoothly through the water. They are able to digest bacteria, algae, and even large organisms by expanding their cytosome which lies at the base of the flagellum. Peranemas are common in water with rich organic nutrients(
Peranema). I was able to identify the Peranema on page 51(source 1).
