The sagavermes guttoplaque replaced its ancestor guttoplaque. It inhabits only the sagaverme phylum on land. Like its ancestor it helps in digestion of food particles its hosts eat. Not only does it get to eat but it keeps the host healthy and thus mutually beneficial to each other. Other than specifying to the digestive system of sagavermes, it has not changed.
Living Relatives (click to show/hide)
These are randomly selected, and organized from lowest to highest shared taxon. (This may correspond to similarity more than actual relation)
None found. Note that this does not necessarily mean it has no living relatives at all, but that, assuming all taxonomy is filled in, its entire phylum is extinct; any relatives it does have likely do not resemble it.
