Abstract

An unique specimen of tuna, showing characteristics intermediate between Euthynnus Lutken and Katsuwonus Kishinouye has been collected off Mangalore in 1980. The present paper embodies a detailed description of its morphological and meristic characters with a discussion on the status of the specimen. Evidences are not conclusive as to whether it is an inter-generic hybrid or a new species. Attention is drawn to the need for a global revision of the genus Euthynnus.
