It is a common misconception that tumbleweeds are plants. On the contrary, tumbleweeds belong to the animal phylum Cnidaria[8]. The tumbleweed is the macroscopic manifestation of the reproductive phase of desert corals (Anthozoa)[7]. When the polyp ######## its nematocysts detach from the main body and dry out in the cool desert sun. Fully desiccated, the nematocysts' total mass approximately is 10% of that in water[8][9]. Its newfound lightness allows the structure to be carried around by gusts of wind. The tumbling motion causes coral spores to be ejected in all directions and subsequently carried away by winds, which deposit the spores far from the original animal, thus ensuring the evolution of genetic diversity within the species[7]. There is debate among marine biologists[who?] as to whether the noble tumbleweed itself is considered an animal on its own. While the dry nematocysts are entirely detached from the original animal, recent studies have shown that the structures appear to respond to certain stimuli. Researchers in California noted[10] that many tumbleweed specimens exhibit a form of chemotaxis. The researches left several tumbleweeds alone in a dark room, half a furlong away from a petri dish filled with desertion and unfunny jokes. After three hours, the researches found that the tumbleweeds were, on average, seven centimeters closer to the petri dish than they were at the start of the experiment. These findings have found mixed reception[11], and the validity of the study itself has been brought into question due to the funding the researchers received from Big Tumbleweed, Inc.
