What fish has green bones?

The garfish, or sea needle, is a pelagic, oceanodromous needlefish found in brackish and marine waters of the Atlantic, the Mediterranean Sea, Caribbean Sea and the Baltic Sea. The garfish is a long and slender fish with a laterally-compressed body, and grows to about 50 to 75 centimeters (20 to 30 in) in length. The jaws are elongated and armed with sharp teeth. The pectoral, dorsal and anal fins are situated well back on the body and the latter two are similar in appearance. Positioning the fins so far back gives greater flexibility to the body. The lateral line is set low on the flanks. The color of the body is bluish green with a silvery grey belly and the bones are green.

Garfish are eaten boiled, fried, baked, barbecued or smoked. They have unusual green bones (due to the presence of bile pigment) which discourages many people from eating them, but the green color is harmless.

Garfish live close to the water surface. They inhabit shallow waters in the spring and summer months to spawn, and head out to open sea in the fall.
