PLATE 65. SARGASSUM FISH (Pterophryne histrto) IN A TUFT OF FLOATING SEAWEED. 



The white spots on the fish resemble the spots of Bryozoa upon the seaweed. The fins of the 

 fish are frayed out and irregular, resembling somewhat the fronds of the seaweed. Two pairs of 

 the fins are modified to form clasping organs, by means of which the fish clings to sprays of the 



seaweed.
