The family Agonidae consists of ray-finned fish commonly called poachers, distinguished by their bodies covered in bony plates or armor. These fish inhabit cold marine waters, particularly in the Northern Hemisphere. Imagine them as the armored tanks of the ocean floor. They are generally small, bottom-dwelling creatures that feed on small invertebrates. They play a unique role in the marine ecosystem. They represent a fascinating example of adaptation to harsh environments.
