Surrounding the exit area of the Oceans building are several exhibits that feature a variety of marine mammals. Inside Oceans, there are underwater views of the sea lion and seal exhibit and the polar bear exhibit. The Zoo has California sea lions, harbor seals and grey seals in its collection and features daily sea lion chats. Next to the polar bear exhibit is the walrus pool. The Zoo is one of only a few institutions in North America to house Pacific walruses, which are also featured in daily chats. The last marine mammals at the Zoo are Atlantic bottlenose dolphins
