Etymology: Gyrinomimus: Greek, gyrinos = tadpole + Latin, mimus = imitator (Ref. 45335); johnsoni: Name 'johnsoni in honor of late Dr. G. David Johnson, National Museum of Natural History (USNM), for his great contributions to our knowledge of cetomimids, and for his encouragement in our study.

Short description Identification keys | Morphology | Morphometrics
Vertebrae: 53 - 55. This species is distinguished from its congeners by the following set of characters: medial tooth patch on first gill arch 2-4; POP 0-2; IO 7 + 0 = 7; inner ~ 3-5 rows of teeth in the anterior jaws in diagonal rows(in specimens < ~ 150 mm SL); anterior margin of anteriormost GRI reaching near anterior margin of the copular tooth plate, often before anterior margin of copular tooth plate; cavernous tissue only surrounding anus; absence of anal lappets; absence of filaments on fourth gill arch tiny or nearly, length < 17.3% filament on first arch; cavernous tissue, when discernable, only around anus; vertebrae 30-33 + 22-24 = 53-55; dorsal-fin rays 16-19; anal-fin rays 17-20; lateral-line pores 16-19; lateral-line scales 15-18; and copular tooth plate rather slender, greatest width 3.2-4.7 in length. (Ref. 138879).
Body shape (shape guide): elongated.
