Abstract

Kyphosis has not been reported in any Graptemys species (map turtles and sawbacks). We captured four kyphotic individuals of Graptemys oculifera from the Pearl River system, Mississippi, with three individuals recaptured 5 to 12 yrs later; one juvenile female had measurable growth, and two adult females had negligible growth. All kyphotic individuals were females, with an overall occurrence rate of 0.10% (4 of 3830 individuals) at five G. oculifera sample sites.
