To provide a device for removing the eyeballs of Watasenia scintillans, capable of automatically removing the eyeballs of the Watasenia scintillans without injuring the bodies of the Watasenia scintillans by forming the device in a specific structure.

This device for removing the eyeballs of Watasenia scintillans is obtained by disposing a cylinder drum 3 in an inclined horizontal posture making it possible to change the inclination angle and in a rotatable state, using the inclined upper side of the cylinder drum 3 as a charging port 7, connecting a charging conveyer 8 for carrying and supplying the Watasenia scintillans into the cylinder drum 3, using the inclined lower side of the cylinder drum 3 as a discharging port 9, and subsequently connecting a carrying device used for checking the treated Watasenia scintillans and comprising a plurality of arranged screw-like rollers each having spiral grooves on the surface in a rotatable state to the discharging port 9. The cylinder drum 3 is formed by processing a net 2 having meshes permitting the passage of the eyeballs of the Watasenia scintillans in a cylindrical shape.
