   • 1995 December 14, Natalie Angier, “Flyspeck on a Lobster Lip Turns Biology on Its Ear”, in The New York Times‎, →ISSN:

     While biologists are perpetually finding new species, they can almost always fit the organism into one of the existing taxonomic pigeonholes by which scientists classify life forms. The discovery of an organism so unusual that it needs its own phylum is an extremely rare event.
