The marinovermes guttoplaque has replaced its ancestor the guttoplaque in the seas, and lives mostly inside finworms and gilltails. It eats not only the left over food materials in the digestive system, but will also help in digesting excess sea salts and minerals, the sagavermes are otherwise unable to absorb. In time, it has developed a special green organelle next to its nucleus to specialize in extracting excess salts from the sagavermes' body.
It has evolved a flagellum for moving faster and avoiding predatory microorganisms that the sea sagavermes eat but don't digest. Otherwise, it's the same as its ancestor.
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.
