ABSTRACT
Congenital deformities are relatively common in rays and sharks. The present study aimed to describe a case of bicephaly in an R. lalandii embryo. Through radiographic images and evaluation of the external and internal condition of the embryo in comparison with a young of the year with no deformities of the same species, it was possible to characterize the abnormality observed. Such data are important to determine the frequency and types of anomalies observed in elasmobranchs, thus
allowing greater knowledge about developmental abnormalities in the group and their possible causes.
RESUMO
Deformidades congênitas são relativamente comuns em raias e tubarões. O presente estudo teve como objetivo descrever um caso de bicefalia em um embrião de R. lalandii. Através de imagens radiográficas e avaliação da condição externa e interna do embrião em comparação com um jovem do ano sem deformidades da mesma espécie, foi possível caracterizar a anormalidade
observada. Tais dados são importantes para determinar a frequência e tipos de anomalias observadas em elasmobrânquios, permitindo assim o maior conhecimento sobre as anormalidades de desenvolvimento no grupo e suas possíveis causas.
