Courtship and fertilization processes and embryonic development of Antennarius striatus were observed under controlled conditions after the capture of two adult specimens in Bahía Gaira (Santa Marta – Colombian Caribbean). The objective was to describe the reproduction mechanisms as well as the different stages of embryonic development, to characterize the behavior and diagnostic features of this species in its first life stages, useful for ichthyoplankton samples identification. Some of the more important events that happened during these processes were: 1) change of coloration, 2) male dance previous to fecundation, and 3) death of the female. Soon after egg-laying, samples were taken periodically; meristic and morphometric data were taken from eggs and larvae. Egg diameter ranged between 566 and 586 µm and notochordal length varied between 1169 and 1252 µm. Estimated time of development from gastrula to early postlarvae for this species is 122 HPF

Key words: Antennariidae, larvae, development, ichthyology
