Definition

Noun: 1. A taxonomic order of marine fishes: "Pediculati" refers to an order of spiny-finned marine fish, historically used in classification. These fish are characterized by modified pectoral fins that resemble arms and a distinctive dorsal fin spine used as a lure. * Key Characteristics: This group is defined by having pectoral fins located at the ends of armlike processes and a long, movable spine on the head (derived from the first dorsal fin ray) that acts as a bait to attract prey to their large mouths.
