AbstractWe provided a water‐cornea interface to correct the usual aerial myopia encountered in fundus photography of marine mammal eyes. The 12Tursiopseyes were consistent for vascular structure, optic papillae, dimensional components and tapetal coloration. Multiple photographs were assembled to produce one ocular fundus typical ofTursiops truncatusand one forGrampus griseus.The eyes have a vestigial hyaloid vessel and an optic disc („blind spot”) that occupies the center of the fundus. The disc is bounded in both species by a vascular structure that is continuous with a (retrobulbar) perineural organ called the ophthalmic rete. The vascular trees of the fundus do not suggest an area of specialization for high resolution. Both species exhibit total tapetalization. Tapetal spectral reflectance did not vary betweenTursiops.There was, however, a difference between species in the short wavelength regions of the spe
