Retinal topography and visual acuity in the Florida manatee, Trichechus manatus latirostris. [Title of Engl. transl.: Ganglion layer topography and retinal resolution of the Caribbean manatee Trichechus manatus latirostris.]
Doklady Akademii Nauk (Rossiiskaya Akad. Nauk) 355(3): 427-430. 3 figs. July 1997.
–In Russian. Engl. transl.: Doklady Biological Sciences 355: 392-394; this version is the one indexed here. Describes the shape and proportions of the eyeball and its major components, as well as ganglion cell density and distribution on the retina. The retina contains no area centralis or visual streak, merely an area of slightly increased cell density in the ventral sector. The manatee has the lowest degree of retina differentiation among all marine mammals studied, and its retinal resolution value (20') is also much lower than those of nearly all other marine mammals. Concludes that the manatee can probably distinguish only nearby objects.
