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.
东热带太平洋首个白座头鲸记录,新大翅目
摘要异常的白色脊椎动物是色差异常的结果,色差异常可能与几种遗传和环境因素有关。2022年10月2日,在哥斯达黎加西北部观察到一头驼背鲸母亲Novaeangliae和一头白色小牛。这是东太平洋白驼背鲸的第一个记录。这种物种在哥斯达黎加水域发现,北太平洋驼背鲸的中美洲冬季地面覆盖了南半球驼背鲸的冬季范围。小牛色素沉着,没有明确的结论来确定其白色的确切色差。摘要异常白色的脊椎动物是颜色异常的结果,颜色异常可能与各种遗传和环境因素有关。2022年10月2日,在哥斯达黎加西北部观察到一只新冠巨型座头鲸和一只白色幼崽。这是东太平洋首次记录到白座头鲸。该物种位于哥斯达黎加水域,北太平洋座头鲸中美洲的冬季区域与南半球座头鲸的冬季分布区域重叠。鲸目动物的颜色较低,对决定其白色的确切颜色异常没有明确的结论。
