Abstract :This study was conducted to determine the substrate preferences of hydroid polyps sampled in eight different stations on the coastline of Antalya Bay. Sampling was performed by freedive to identify the hydroid polyp fauna and certain physicochemical (salinity, temperature, dissolved oxygen, electrical conductivity, chl-a) and biological characteristics were determined. A total of 35 hydroid species were identified as epiphytic, epilithic and epizoic in the region. The most commonly preferred substrates by the species were; rocks (20 species), Ellisolandia elongata (J.Ellis & Solander) K.R.Hind & G.W.Saunders, 2013 (18 species), Balanus sp. Costa, 1778 (9 species), macroalgae Posidonia oceanica (Linnaeus) Delile, 1813, and leaves (8 species). Among all species, one species prefers just epilithic substrates, four species prefer only epizoic substrates, and seven species prefer only epiphytic substrates. Acauloides ammisatum, Eudendrium sp., Turritopsis. nutricula, Pennaria. disticha, Clytia noliformis, Halecium tenellum, Halopteris diaphana, Dynamena disticha and Salacia desmoides are found in all substrate types (EP,EZ,EL).
