We describe seven stages for the embryonic development ofCryphiops caementarius (Molina, 1782) using both light and scanning electron microscopy. Thirty ovigerousfemales were captured in Limarí River, Chile, and maintained separately in three 35 liter tanks with temperaturesof 15, 22 and 28 ºC. At the same time, some embryos were separated from the females and placed in a 100 mlbeaker for in vitro culture at 15 °C. Duration of development at 15, 22, and 28 ºC was of 36-39, 30-32 and 25-28days, respectively, with no differences observed between in vitro and in vivo cultures. Seven development stageswere observed: (I) homogeneously distributed vitellum; the embryo cleavage leads to the morulae stage; (II) firstembryonic stage; antennule, antenna and ocular globe are present; (III) primordium lengthens, and the outlinesof the pereiopods can be observed; ocular pigmentation appears as a curved line; (IV) ocular pigmentation inhemispherical form; the antennae develop, and the first red pigmentation appears near the eye; heartbeat is visible;(V) the pereiopods touch the base of the antennae; the ocular globe is more evident, in a oval form; (VI)eyes are faceted, and both antenna and third abdominal segment with chromatophores; ocular pigmentation asspherical form; (VII) ocular globe with spherical eye pigmentation and facets on the surface; star-shaped chromatophoreson the appendages. Egg volume increased from 0.082 mm3 at the beginning of the development to0.125 mm3 close to hatching, representing a rise of 65.6 %. The diameter of the embryo and eye pigmentationmay be used as growth parameters. Rev. Biol. Trop. 55 (Suppl. 1): 15-24.
