RANDALL: SURVEY OF CIGUATERA AT MARSHALL ISLANDS 



Figure 44. — Epibulus insidiator, 185 mm SL, Enewetak, Marshall Islands. 



Figure 45. — Hipposcarus harid, 282 mm SL, Rangiroa, Tuamotu Archipelago. 



Of four specimens, 340-412 mm SL, 1.3-1.8 kg, 

 obtained at Enewetak, three were nontoxic, and 

 one produced a reaction of 1. 



Reporting on the stomach contents of Ceto- 

 scarus bicolor, Scarus sordidus, and seven uniden- 

 tified species of Scarus in the Marshall Islands, 

 Hiatt and Strasburg (1960) concluded that they 

 fed mainly on live coral. This is contradictory to 



the investigation of scarid food habits by Wood- 

 Jones (1910), Choat (1966), Randall (1967, 1974), 

 Rosenblatt and Hobson ( 1969), and Hobson (1974). 

 Randall (1974), however, presented evidence that 

 the largest of the parrotfishes, Bolbometopon 

 muricatus, feed heavily on living coral. Also 

 Glynn et al. (1972) listed three scarids as coral 

 predators off the Pacific coast of Panama.
