Maine State Aquarium
It may not seem like the deep blue at this small aquarium, but when you lean closer to one of the tanks, you're seeing into an entire aquatic world with a big message of ocean conservation, research, and education. Maine State Aquarium exhibits a selection of the same plants and animals found in the nearby ocean, including colorful anemones and wolffish with long, sharp teeth. Local fishermen bring in everything from 17-pound lobsters, while tide-pooling classes take kids down to explore the rocky shore. Back inside, a touch tank allows guests to handle horseshoe crabs, sharks, sea stars, and sand dollars as staff help direct and answer questions about the creatures.
