Plectognath Fishes of the Superfamily Triacanthoidea: Monographs of The Academy of Natural Sciences of Philadelphia, No. 16
James C. Tyler (au)
Hardcover (no d.j.)
The Triacanthoidea is one of 7 superfamilial groupings presently envisioned for the Plectognathi, an order of primarily marine fishes derived of a percoid ancestry during the Eocene. The approximately 320 recent species of plectognaths, of which 26 are triacanthoids, are notable for a high degree of diversity in structure & way of life. The great diversity that is evident between the families of plectognaths also is seen within some families, but not in others. In the case of the triacanthoids, the deep water Triacanthodidae range from relatively normal species through intermediates to weirdly specialized forms with extremely long tubular snouts, while, in comparison, the shallow water Triacanthoidae are of rather uniform configuration. Over 100 illus.
