The morphology of bluefin tuna (Thunnus orientalis) contributes greatly to high-speed swimming with oscillating the fin at high frequency so called thunniform mode. The form of the body, fusiform, result in small resistance force because the pressure drag is less than that of a bluff body shape. The main propulsion and the lift force are produced by the caudal fin and the pectoral fins, respectively. However the fluid dynamic characteristics of bluefin tuna are not clarified accurately. In this study, the fluid dynamics of bluefin tuna such as drag and lift force and velocity fields around the body were evaluated by using CFD (computational fluid dynamics) analysis.The drag and lift force are 79.2% (.0.076 N) and 129% (0.124 N) of the submerged weight, respectively and the momentum to the gravity centre is 0, if the flow speed amounts 2.6BL/s (0.75m/s) with a 0 degree angle of attack. We show pressure on body surface on a figure. There is no vortex and turbulent flow around the body because of its fusiform.
