1. 1. The sera of ten species of fish from the family Cottidae were examined for pigmentation. Eight species were found to have brightly colored sera with the coloration ranging from blue-green to red. 2. 2. The net coloration of the serum is due to varying amounts of red, blue and green chromoproteins. 3. 3. The chromophore of the blue and green chromoproteins was found to be biliverdin; the chromophore of the red chromoprotein is also a bile pigment possibly related to the phycobilins found in algae. 4. 4. The concentration of biliverdin in Cottidae (>0.06mg/ml) serum is significantly higher than the threshold bilirubin serum values in jaundice.
