It has been described in several books that the fishes of the genus Diodon are aglomerular. To ascertain this, I obtained three specimens of the porcupine fish D. holacanthus and did detailed histological examinations of the kidney tissue using H-E or Bowie's stain. Consequently, I con-firmed the presence of the glomeruli and the juxtaglomerular cells in the kidney tissue. Therefore, the description of Diodon spp. as aglomerular fishes should be corrected.
