Intrinsic localized modes (ILMs) in two dimensional Fermi-Pasta-Ulam lattices are investigated. We consider in-plane vibrations of particles which have two degrees of freedom. We find two types of ILMs, quasi-one dimensional ILM and two dimensional ILM. Effect of interaction of second nearest neighbor lattices on stricture is also discussed.
