Fig. 94. PoRTUGUBSE-MAN-OF-wAR-piSH. Nomeus gronovii. 



This native of tropical waters (West and East Indian) is abundant in the 

 Sargasso Sea and not uncommon in southern Florida; at more northern points on 

 the United States coast it occurs as a straggler. Dr. Jenkins took an example 

 half an inch long in a tow net at Beaufort in the summer of 1885, and states that 

 in fall the fish is common, "then found only in a medusa, the medusa never being 

 found without a Nomeus". Prof. Wilson also records the fish as occurring at 

 Beaufort in the bell-cavity of the medusa Stomolophus. The present author 

 has noted the occurrence at Woods Hole, Mass., of as many as 12 of these fish 

 under a single specimen of the medusa known as the "Portuguese man-of-war" 

 (Physalia). The usual length attained is 5 or 6 inches.
