Early evolution of the gular musculature and its innervation in ray‐finned fishes
The Anatomical Record, EarlyView.Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

THE CELLULAR STRUCTURE OF LYMPHOMYELOID TISSUES IN CHIMAERA MONSTROSA (PISCES, HOLOCEPHALI)
The Biological Bulletin, 1986 The ultrastructure of the main lymphomyeloid organs of the holocephalan fish, Chimaera monstrosa, is presented. The thymus is well developed even in adults. It is densely packed with small and large lymphocytes, the former predominating. The ultrastructure of C. monstrosa's lymphocytes is similar to that of mammalian ones. The lymphocytes show intimate

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
