Summary This contribution presents a brief morphometric description of adult females and embryos of the ray Gymnura altavela. Two females, pregnant with a total of five embryos, were captured in Rio de Janeiro, southeastern Brazil, and their morphometry was compared to their respective embryos. The embryos showed higher body proportions (%DW) than adults, regardless of sex, which may be an effect of ontogeny.
