Hyperkyphosis in longnose gar (Lepisosteus osseus) of North Central Texas

January 1, 2011

Two mature female longnose gar (Lepisosteus osseus) exhibiting severe hyperkyphotic spinal deformities were captured during the 2010 spring spawn at Lake Arrowhead, Clay County, Texas. Yet, despite their deformities and impaired motility, both longnose gar were in overall good condition. Hyperkyphosis in both longnose gar resulted from fused trunk vertebrae in the affected areas. Results of morphological examinations and computerized tomography (CT) scans showed no evidence of injury-induced responses and suggested a congenital or possibly environmentally induced aetiology for disruption of the normal vertebral segmentation process.
