How to identify a Rainbow Runner
There is a groove on the back and another on the venter in front of the tail fin of this species, but there are no bony scutes on the sides. The first dorsal fin has six spines and the second dorsal fin has one spine and 25-27 connected soft rays, followed by a two-rayed finlet. The anal fin consists of a single detached spine that is covered by skin in most specimens over 12 inches long, followed by another spine with 16-18 connected soft rays and a two-rayed finlet. These fish range from a couple of pounds up to 15-20 pounds.Rainbow runners closely resemble the cobia in shape, but can be distinguished by its coloration as well as the finlet after the dorsal and anal fins. The back of the rainbow runner is blue-green. On each side there is a broad, dark blue, horizontal stripe near the back and one or two narrower, light blue stripes beneath the broader stripe. Between and around these blue stripes, the sides are cadmium yellow. The belly is white or silver, often with a yellow or pink tint. The tail is yellow and the other fins are a greenish or olive yellow.
