plectognathi
Noun A former taxonomic order of marine fishes characterized by fused jaw bones, small gill openings, and bodies often covered with bony plates or spines. This group includes species commonly known as boxfishes, filefishes, puffers, and triggerfishes.
The term plectognathi is used in scientific and historical zoological contexts to refer to this specific grouping of fish. * Modern ichthyology no longer recognizes Plectognathi as a valid taxonomic order; the fishes are now classified within the order Tetraodontiformes. * The defining features of the plectognathi are their unique jaw structure and body armor.
