Abstract

Cladophora catenata (Linnaeus) Kützing is a filamentous green alga with a highly disjunct distribution in tropical seas (Hoek 1982), and its presence in Türkiye has remained unverified until now. In this study, we report the first confirmed occurrence of C. catenata in the Marmara Sea, expanding its known distribution beyond tropical and subtropical waters. Specimens were collected from the coast of Üsküdar (41°1′13.68″N, 29°0′25.56″E) (İstanbul, Marmara Sea, Türkiye) in July 2024 at a 0.5 m depth and identified based on morphological characteristics. Our findings contribute to the knowledge of marine algal biodiversity in Türkiye and emphasize the need for further monitoring of Cladophora species in the Eastern Mediterranean and adjacent seas, particularly in the context of changing environmental conditions and species dispersal patterns.
