A SCIENTOMETRIC REVIEW ON LEUCISM IN WILD DOLPHINS
Boletim do Laboratório de Hidrobiologia, 2020 ABSTRACT Leucism, a category of partial albinism, has been observed in several marine mammals, including cetaceans. The underlying mutations, however, have not yet been identified, and a severe knowledge gap concerning this condition in these animals, has, therefore, been noted. In this context, the present study performed a scientometric-based review
