Square Enix has updated the official Final Fantasy XIV: Online website with a new Bestiary section. A couple of the monsters such as the Morbol (usually known as Marlboro) and Cactuar will be familiar to most Final Fantasy fans and some of the other ones have made already an appearance in Final Fantasy XI: Online but they have been slightly redesigned except for the Raptor that looks exactly like the one seen in Final Fantasy XI.
