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