Resumen

Se ha reportado leucismo en al menos 14 especies de cetáceos, incluido el delfín de Risso (Grampus griseus). Se avistaron y fotografiaron delfines de Risso con pigmentación anormal en el norte de la isla de Faial, archipiélago de las Azores, en 6 eventos diferentes entre 2020 y 2023. En 2020, se avistaron una cría y un juvenil/subadulto dentro de un grupo de más de 100 individuos. Una cría con piel pálida y ojos oscuros fue observada en 2021, 2022 y 2023 en la misma zona seguida del mismo adulto dentro de un grupo de aproximadamente 12 individuos, incluso 3 juveniles, todos con coloración típica. Este es el primer registro de delfines de Risso leucíticos silvestres en el Atlántico, lo cual puede ser útil en futuros estudios poblacionales y de hipopigmentación en una especie de delfín que se conoce se vuelve completamente blanca con la edad.
