A total of 164 individuals of Hippocampus coronatus were collected from an eelgrass bed in Dongdae Bay, Korea from September 2006 to August 2007. The number of individuals of H. coronatus was higher in September 2006. The size of H. coronatus ranged from 2.4 to 9.3cm in height (Ht), and most of individuals were small size below 5cm (Ht). H. coronatus was a carnivore which consumed mainly gammarid amphipods and copepods. Its diets also included a small amount ofmysids, ostracods, brachiopods, caprellid amphipods, bathynellaceas, isopods, tanaids, and ascothoracids. The diets of H. coronatus underwent size-related changes; smaller individuals consumed copepods, while larger individuals ate gammarid amphipods and mysids. The dietary breadth index of H. coronatus was increased with increasing of their size.
