The California Academy of Sciences is taking on the National Aquarium in Baltimore in the days leading up to the 49ers-Ravens Super Bowl showdown on Sunday, museum officials said.
The two aquariums are participating in the Super Fish Bowl and using social media to get fans involved in the friendly duel.
Using the hashtag #SuperFishBowl to follow along on Facebook, Twitter and Instagram, both aquariums are asking fans to like animal photos from the competing institutions.
On game day, the aquarium from the winning city will receive $1 from the defeated team's aquarium for each "like" on their Super Fish Bowl photo, museum officials said.
The winning donation will be made to either the National Aquarium's Marine Animal Rescue Program or the California Academy of Sciences' Coral Conservation program.
No matter which aquarium proves victorious, the donated money will go toward animal care and conservation efforts, officials said.
The friendly competition will kick off today with divers at each aquarium wearing their home team jerseys during daily dive presentations at their respective coral reef exhibits.
In San Francisco, a diver at the Philippine Coral Reef exhibit at the aquarium located at the Academy of Sciences at 55 Music Concourse Drive in Golden Gate Park will wear SCUBA gear with a red-and-gold jersey at 11:30 a.m. and 2:30 p.m.
The diver will have an underwater microphone and will be able to answer reef-related questions from visitors, museum officials said.
Meanwhile in Baltimore, the opposing team in the Super Fish Bowl will have a diver don the Ravens' purple jersey at the National Aquarium's Atlantic Coral Reef exhibit.
