- n. A genus of minute, pale-green, globular, organisms, about one fiftieth of an inch in diameter, found rolling through water, the motion being produced by minute colorless cilia. It has been considered as belonging to the flagellate Infusoria, but is now referred to the vegetable kingdom, and each globule is considered a colony of many individuals. The commonest species is Volvox globator, often called globe animalcule.
from The Century Dictionary and Cyclopedia
- n. A small genus of fresh-water algæ, of the order Volrocineæ and class Cœnobieæ.
- n. [lowercase] A member of the above genus: as, the globate volvox.

And again, I don't want to talk about consciousness, I want to talk about it just as if it was a little bacteria, or a volvox, which is what that organism is.
Man is the most composite of all creatures; the wheel-insect, volvox globator, is at the other extreme.
Another example of conjugation is that of Pandorina, an alga allied to the well-known volvox.
In explaining the facts of reproduction, I would therefore suggest that you should begin with the lowest rung of the ladder, the simplest organisms, such as the amoeba or the volvox.
Just as dangerous, just as self-centred, as in its small way is that vegetative organism the volvox, which, when food is scarce and the race is threatened, against possible need of insemination, creates separate husband cells to starve in clusters, while ` she 'hogs all the food-supply for the production of eggs.
There is a class of wheel-animalcules termed _rotifera_, of which the revolving volvox is one example.
The revolving volvox likewise increases by growth until it becomes a society of animals, a multiple system of individuals.
This monad was once supposed to be a single animal, but the microscope shows it to be a group of animals connected by means of six processes, and each little growing volvox exhibits his red-eye speck and two long spines, or horns.
There are still to-day some organisms that remain throughout life at the structural stage of the blastula -- hollow vesicles that swim about by a ciliary movement in the water, the wall of which is composed of a single layer of cells, such as the volvox, the magosphaera, synura, etc.
The former I suppose to be beholden to a single living filament for their seminal or amatorial procreation; and the latter to the same cause for their lateral or branching generation, which they possess in common with the polypus, tænia, and volvox, and the simplicity of which is an argument in favour of the similarity of its cause.
