The sergeant major is a species of damselfish that can be found all throughout the Atlantic Ocean in shallow waters.

Sergeant major fish

A lighter body color with a yellow top and five to six dark stripes makes the sergeant major visually distinctive. These fish can grow to be up to nine inches long, but are typically around six inches long. They feed on plankton, invertebrates, smaller fishes and algae.

The name for this fish comes from the black stripes on the side of its body, which resemble the insignia of sergeant majors in the military.  

Sergeant majors tend to gather in groups of several hundred and perform tasks together, such as clean green sea turtles.  

Stay tuned for more behind-the-scenes updates!
