Abstract
Abstract Abnormal white vertebrates are a result of chromatic anomalies that may be associated to several genetic and environmental factors. On October 2, 2022 a Humpback Whale mother Megaptera novaeangliae and a white calf were observed in northwestern Costa Rica. This is the first record of a white Humpback Whale in the Eastern Pacific. This species is found in Costa Rican waters, where the Central American wintering ground of the North Pacific Humpback Whale overlaps the winter range of the Southern Hemisphere Humpback Whale. The calf is hypopigmented, without a clear conclusion about the exact chromatic abnormality determining its white coloration. Resumen Los vertebrados de coloración blanca anormal son el resultado de anomalías cromáticas que pueden estar asociadas a varios factores genéticos y ambientales. El 2 de octubre de 2022 se observaron una madre ballena jorobada Megaptera novaeangliae y una cría blanca en el noroeste de Costa Rica. Este es el primer registro de una ballena jorobada blanca en el Pacífico oriental. Esta especie se encuentra en aguas de Costa Rica, donde la zona de invernada de América Central de la ballena jorobada del Pacífico Norte se superpone con el área de distribución invernal de la ballena jorobada del hemisferio sur. El ballenato es hipopigmentado sin una conclusión clara sobre la anomalía cromática exacta que determina su coloración blanca.
