Two specimens of Epinephelus costae (Steindachner, 1878) have been observed in the rocky littoral zone of the northeastern Sea of Marmara in the early days of October 2024. E. costae is recorded for the first time from the Sea of Marmara. The present recording also emphasises that the northward migration of thermophilic Mediterranean species is gradually reaching higher latitudes.
