Abstract

Two jellynose fish captured in southern Brazilian waters were identified and compared with the previous descriptions of ateleopodid species to improve our understanding of the diversity and distribution of these fish off Brazil. The body of each individual is elongate, tapering, and posteriorly compressed, with a large, robust head with relatively small eyes (~7% head length), a short trunk and a long tail. Radiographs of the specimens show two undeveloped pelvic rays buried in integument and five caudal rays originating from the last vertebrae which are exclusive characteristics of Ijimaia antillarum.
