Rainbow Runner (Elagatis bipinnulata) Fish Description

Rainbow Runners are a species of Jack that are known for their seven colors that reflect off their bodies when the light hits them. In bad lighting, however, Rainbow Runners appear to be crystal blue in color. They are torpedo-shaped, allowing them to swim quickly with little resistance. Their dorsal and anal fins are short but run along the posterior. However, the dorsal fin starts at the midpoint of the body whereas the anal fin starts a little bit after. However, the dorsal fin appears to be split into two: one main fin and the other one is a tiny finlet which is at the base of the deeply forked tailfin. Its fins appear to be predominantly yellow.

The Rainbow Runner also has a bright blue lateral line that runs across its body which emphasizes the rainbow colors. Its whole body is made up of different colors. Dorsally, its body is olive green while the belly is white. Across its body, the Rainbow Runner also has bright yellow stripes.

 

Diet and Size

Rainbow Runners are fast swimmers so catching their prey is no problem. They’re piscivorous but they also eat their fair share of crustaceans such as shrimps and crab. They also enjoy making a feast out of cephalopods such as squids and octopi. However, they can be quite selective with their prey. Rainbow Runners will only choose prey that are smaller than them.

Rainbow Runners grow up to an average of 42-47 inches, almost 4 ft! For their average weight, they can weigh around 15-20 lbs. However, there was a record of a Rainbow Runner reaching 71 inches and weighing 37 lbs 9 oz.
