Thirteen specimens of post-larval and juvenile stages of the Western Atlantic sailfish, Istiophorus americanus, are described, ranging in standard length from 3.9 mm to 208.0 mm, and ten specimens are illustrated, all from the Florida Current. These are compared with previously published descriptions and illustrations of young Istiophoridae. The developmental changes from post-larval to adult are described and the general biology is discussed. Florida populations of sailfish spawn during the early summer near shore and no migrations are observable in Florida waters. The food and methods of feeding are described and the results of tagging operations are given.
