Come in costume and celebrate Halloween with the wild ones at the Tennessee Aquarium, like bizarre seahorses, squirming octopus and menacing toothy sharks. Watch for costumed divers, trick or treat in the galleries and win treasure as you play games. Encounter scales and tails at the animal encounter and dare to touch the unknown.
