[Color changes in Uca rapax (Smith, 1870) Crustacean. Decapode. Effect of an injection of sinus gland extract].
Color changes of Uca rapax (Smith, 1870) of São Paulo's northern littoral were studied in function of injections of sinusgland extracts. When 0.06 of the sinusgland was injected the melanophore's pigments attained a maximal dispersion in 45 minutes and the effect remained during 6 hours. The animals with one eyestalk kept their normal chromatic behavior. It was observed that the rate of melanophores dispersion varies directly to the hormone concentration.
