The Georgia Aquarium contains one of the largest living reef exhibits of any aquarium in the world. Few people ever get an opportunity to snorkel at a reef, but at an aquarium, the entire family can be mesmerized by the dazzling color of a reef and its diverse inhabitants. The reef is a place to discuss how God designed creatures that could live together in a rich community of life. This aquarium depicts life in a tropical Pacific coral reef.

The whale shark is actually not a whale but a fish. And it's the biggest one at that. Besides two Japanese aquariums, the Georgia Aquarium is the only North American aquarium that houses these unique creatures. Despite its great size, this giant is not dangerous to humans. Its 4-foot-wide (1.2 m) mouth is located at the front of their heads instead of underneath their snouts like most shark species. Surprisingly, the largest shark in the ocean eats some of the smallest prey-feeding mostly on plankton. Like other sharks, the design features of the whale shark are well-suited for their environment and diet.

Horseshoe crabs showcase God's design in numerous ways. Though their long tails (telsons) look intimidating, they are not dangerous. Horseshoe crabs use their tails as rudders when they move, and when they accidently tip over onto their backs, they use their tails to flip upright. The smooth front part of its shell protects the eyes, mouth, brain, heart, pincers, and legs. Its six pairs of legs are used for bringing food to its mouth, swimming, and walking.

Evolutionists consider horseshoe crabs to be a "living fossil" because fossils of these creatures—thought to be millions of years old—look identical to modern-day horseshoe crabs. But those who believe that the Flood buried most fossils—just around 4,350 years ago—would expect many living creatures to look very similar to the creatures that died not long ago.
