Under the microscope, the biologist observed a single zooid propelling itself with a tail-like flagellum.

The museum's new exhibit features a series of detailed, zooid sculptures that blur the line between art and biology.

The reef's colony contained hundreds of tiny zooids, each performing a specialized role in feeding and defense.

The marine biologist documented the zooidal structures that connected the colonial organisms.

The botanist described the fern's reproductive process as zooidogamous, noting that its sperm cells are motile and swim to the egg.

The botanist observed that several flowers were zooidiophilous, apparently adapted to attract small mammals for pollination.
