Summary Here we describe the embryonic development of Salvator merianae external morphologic features, as based on observation of 28 embryos across different days of incubation at 31 ± 0.5°C. Observed developmental stages were grouped and classified into the early, middle, and late periods. The early period (Stages 3–11) is distinguished by the origin of the encephalic vesicles, sensory placodes, pharyngeal arches, and degree of body flexion and rotation. The medium period (Stages 8–15) is distinguished by limb differentiation and by cranium‐facial characteristics. The late period (Stages 15–18) is determined by scale patterns, pigmentation, and embryo growth.
