During the pond survey, I collected several daphnias with a fine-mesh net to study their feeding behavior.

The ecology students observed how daphnia responded to changes in water temperature under the microscope.

The museum's new exhibit explores Daphnian motifs in Hellenistic sculpture.

The researcher discovered a new Daphnian in the pond and began studying its behavior.

The Daphnians celebrated the harvest with a festival that attracted visitors from neighboring islands.
