Butterfish ; Dollarfish 



Middle Atlantic Coast in waters near shore, and each one is almost 

 invariably accompanied by 10 or 12 or even more young butterfish, 

 seeming to seek shelter under their disks, and perhaps obtaining a 

 supply of food from among the numerous soft bodied invertebrates 

 that are constantly becoming entangled with the floating streamers 

 of their protectors. This position is not always safe for the little 

 fish, as they are sometimes destroyed by the tentacles of their 

 protector which are provided with powerful sting or lasso-cells. 

 Though the fish are, by this commensal arrangement, safe from the 

 attacks of larger fish, they often fall victims to the stinging power of 

 the jelly-fish and are devoured.
