An immature male specimen of Carcharhinus falciformis (Bibron, 1839) was caught by a commercial long-liner off Samandağ coast (Iskenderun Bay, northeastern Levant Sea, Turkey), on 2nd of November, 2021. This record is the fourth observation of this species in Turkey. Monitoring the coastal occurrences of the silky shark throughout its distribution range is critical, where the species is considered as very rare.
