Hyperostosis in Fishes: An Update With New Species Records
Journal of Morphology, Volume 285, Issue 11, November 2024.Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.
