Summary: The aim of this paper is to study certain subclasses of bi-univalent functions defined by generalized Sãlãgean differential operator related to shell-like curves connected with Fibonacci numbers. We find estimates of the initial coefficients \(|a_2|\) and \(|a_3|\) and upper bounds for the Fekete-Szegö functional for the functions in this class. The results proved by various authors follow as particular cases.
