SEA LIFE Grapevine Aquarium is swimming in holiday cheer this December. Experience a dive show like no other as Scuba Diving Santa, along with his elf, make a jolly appearance in a water wonderland amongst the fish, sharks and stingrays in SEA LIFE's 160,000-galloon ocean tank. Pose for pictures and find out if Scuba Diving Santa thinks you’ve been naughty or nice. Other festive fishy activities include a meet and greet with Santa Sharky, finding the aquarium’s mischievous elf Minnow and snapping a selfie, and writing holiday cards to your favorite sea creature. Scheduled dives occur at 11:30 a.m. on Wednesdays and Saturdays, December 12, 15, 19 and 22. Holiday activities are included in the price of admission.
