A schooling species that occurs in the tropical inshore waters of the open seas.
The Bigeye Scad is bluish-green to green above grading to white below. There is black opercular spot and sometimes a yellow stripe along the side of the body. It has adipose tissue covering the eye with the exception of an oval slit positioned over the pupil. There is a deep groove in the lower margin of the gill opening, with a large papilla above it.
It is a schooling pelagic species that occurs in tropical inshore waters circumglobally.
In Australia it is known from north-westerm Western Australia around the tropical north of the country and south to northern Queensland. The fish in the image was caught at Lord Howe Island, New South Wales and thus represents a significant range extension for the species (pers. com. W. Smith-Vaniz, April 2006).
