Daily Rhythms in Retinal pigment movements were observed in crab eyestalk. The crab B. jaquimontii acclimatized to laboratory conditions were considered. The three groups: natural photoperiod (6:18), a group kept in constant darkness (12:12) and a group kept at constant light (24L: OD) was studied for three days. After begin of experiment, the eyestalk were excised for every 4 hr interval, to determine the position of retinal pigments. The method adapted by Lazzari (1992) and Reisenman et al (1998) were used.
