Critical Flicker Frequency in a Harp Seal: Evidence for Duplex Retinal Organization

Critical flicker frequency (CFF) was investigated in a free swimming harp seal using behavioral techniques. The resulting CFF vs intensity curve indicates a definite rod/cone break, suggesting a duplex photoreceptor population, whose presence had not been observed in previous morphological reports.
