Abstract

Pomadasys is a genus of Haemulidae family, order Perciformes, living in the Persian Gulf. The members of Pomadasys are known as Grunters (Sangsarmahian). The aim of this study was focusing on Javelin Grunter, Pomadasys kaakan (Cuvier, 1830) from anatomical points of view to provide some basic knowledge to facilitate subsequent decision makings for marine culture, resources preservation, health keeping and disease diagnosis of this marine fish. Eleven javelin granter (total length: 32.5±5.83SD) were caught in Hormuzgan fishing harbours, then an incision was made on the abdomen to penetrate the fixative (formalin solution 10%) and transported to aquatic laboratory of veterinary faculty for anatomic investigations of liver, spleen, pancreas and urinary system. The position, adjacencies and characteristics of any of the mentioned organs were expressed. The liver is divided into two right and left portions (pedicles) which left one is bigger and are connected to each other making an uncommon loop shape. The spleen of grunter fish is a long and dark organ located inside the intestinal meso and under the right pedicle of liver. The pancreas is located between two parts of intestine and after the second intestinal curve in the form of disseminated and pink tissue. The two kidneys are located as lobulated twain organs on the top of swim bladder and in the ceiling of abdominal cavity anteriorly began from the side of the esophagus (where right and left pedicles of liver are connected) and finally ends to the ureter.
