How to Identify Crossback Hogfish

To identify Crossback Hogfish (Bodianus mesothorax), look at these key features.

Physical Characteristics

Body shape

compressed

Coloration

Distinctly bicolored. The anterior half of the body, including the head and pectoral region, is typically bright yellow to orange. The posterior half, from approximately mid-body to the caudal fin, is dark purplish-brown to black. A sharp, vertical demarcation line separates these two color zones. The dorsal, anal, and caudal fins often reflect the color of the body section they originate from, with the caudal fin usually dark.

3. 3

   Size
