Science -- and Pez -- in San Francisco

Visitors get a bird’s-eye view of the living roof, which features plants and skylights, at the Academy of Sciences. The museum’s exhibits include a planetarium and an aquarium, but the main attraction is Rainforests of the World.  (Ken Hively / Los Angeles Times)

Fish are viewed from above and below inside the aquarium at the museum in Golden Gate Park. The aquarium is home to 38,000 animals from around the globe, representing more than 900 species — everything from African penguins to stingrays to piranhas.  (Ken Hively / Los Angeles Times)

Gaze into the aquarium’s Philippine Coral Reef — it’s one of the deepest exhibits of live coral in the world. Keep an eye out for blacktip reef sharks, stingrays and colorful reef fish. And both soft and hard coral, of course.  (Ken Hively / Los Angeles Times)

Penguins cozy up inside their exhibit. Get there at the right time, and you can watch their feeding.  (Ken Hively / Los Angeles Times)
