Emperor Akihito, like his father before him, is a scientist with a passion for studying marine life. Although he was never able to pursue a doctorate in the field, Akihito has continued his studies and research throughout his life.
He's published extensively in ichthyology and genetics. Akihito's most recent article is titled "Speciation of two gobioid species, Pterogobius elapoides and Pterogobius zonoleucus revealed by multi-locus nuclear and mitochondrial DNA analyses." You can read an abstract here.
