Northern minke whales can be distinguished from other rorquals by a well - defined white band located on the middle of their dark pectoral flippers. (animalplanet.com)

The evolutionarily enigmatic gray whale (Eschrichtius robustus) is placed among rorquals, and the blue whale genome shows a high degree of heterozygosity. (advances.sciencemag.org)
