Peristediidae

The Peristediidae family, also known as armored sea robins, are a group of deepwater fish that are distinct from scaly sea robins due to their bodies being covered in bony plates rather than scales. These fish are flattened and inhabit deep waters, but otherwise share similarities with their scaly counterparts. Sea robins, in general, are bottom-dwelling fish found in warm and temperate seas worldwide. They possess armored heads, two dorsal fins, and fan-shaped pectoral fins with separate feelers used for locomotion and sensing prey like mollusks and crustaceans. Some sea robins are known for their bright coloration and ability to produce audible sounds using their swim bladders.1
