Bdelloids have survived for millions of years without sexual reproduction, making them a fascinating subject for evolutionary biologists.

The marine biologist studied the bdelloid specimens under the microscope to document their desiccation-resistant adaptations.

The scientist studied a bdelloid to understand how it survives without sexual reproduction.

Even in extreme drought, bdelloid rotifers can survive by entering a dormant state and reviving when water returns.

Under the microscope, a bdelloid rotifer clung to the moss, its tiny cilia beating rhythmically as it fed.
