Seals do not have ear flaps and sea lions do. Both seals and sea lions are carnivorous and feed primarily on fish. On the fifth level of the Aquarium an exhibit simulates an Amazon rain forest of South America. The rain forest, though not submerged, is a world of water in itself. These warm, wet conditions support the greatest diversity of species in the world.
Scientists estimate that only a small fraction of rain forest species have been identified.
The interior of a rain forest is dimly lit. The floor is relatively open, dotted with palms, herbs and ferns. These plants have large leaves that intercept what little light makes it to the floor. The layer between the canopy and the floor is called the understory. The vast majority of the rain forest plants and animals are found in the understory and canopy.
