Euthynnus sp. Nov.? or an Inter-Generic hybrid of tuna: An enigma

E. G. Silas, P. P. Pillai and C. Muthiah
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.
