| Descrizione: | Albinism is a genetic condition in which the melanin pigment protein is either absent or nonfunctional and has occasionally been reported in chondrichthyes. Total albinism in an 18.42 g female adult dwarf stingray, Urotrygon nana, with an 81 mm disc width is described in this paper. The subject was caught using bottom trawl methods 40 m deep off Puerto Madero, Chiapas, Gulf of Tehuantepec, eastern Pacific (14° 31ʼ 6ʼʼ N - 92° 26ʼ 75ʼʼ W). The albino morphometric characteristics were compared with those of normal specimens of the same sex. This paper represents the first record of this abnormality in the family Urotrygonidae. |
