UNDERWATER GUIDE TO MARINE LIFE 



Identification: The mackerellike body is not very compressed. The spiny 

 dorsal is small and the anal is much shorter than the soft dorsal fin. A prominent 

 wide yellow stripe runs along the side and onto the tail. 



Habits: This large and speedy predator travels solitarily, in small pods, or in 

 schools near reefs or over deeper water on the prowl for the small fishes which 

 are its prey. It has the habit of driving its prey into shallow water near shore. 

 It spawns in the summer, probably at sea. 



Similar Species: There are several members of this genus, all of which are 

 best recognized by the general silhouette and fin pattern which they all have 

 in common. The great amberjack, Seriola lalandi, is also called the horse-eye 

 bonito and has the distinguishing mark of many of this genus— the dark stripe 

 running diagonally through the eye from the base of the spiny dorsal to the upper 

 lip. It ranges from Cape Cod to Brazil, being most common in the West Indies. 



The rainbow runner, EJagatis hifinnulatus, has the shape and fins of the 

 Seriola species but has a very striking pattern consisting of four beautiful irides- 

 cent longitudinal stripes of dark blue, Hght blue, yellow, and again hght blue 

 from back to stomach in that order. It is not a common fish, but it is pelagic 

 in all tropical seas, being found north to New York and to southern California 

 in summer. It reaches a weight of 12 pounds.
