From the makers of “Deep Sea 3-D” and “Into the Deep 3-D” come aquarium-style close-ups of eye-amazing life forms. Howard Hall is the director, director of photography and co-writer of the narration for Jim Carrey (“Ace Ventura: Pet Detective”) in this G-rated series of views shot on dual-strip 70mm with side-by-side lenses. You wear lightweight 3-D glasses. The locations are in the Coral Triangle bounded by Indonesia, Malaysia, Papua New Guinea, The Philippines, Solomon Islands, Timor-Leste and the Great Barrier Reef off Australia. Unlike last year’s “Wild Ocean 3-D,” “Under the Sea 3-D” does not go above the surface to document any human neighbors of the sea life. As usual, the message is: aren’t these critters so cool, cute and queer? Let’s not kill them with global warming. There’s not a trace of God’s hand or Darwin’s theory. As natural history, this is elementary school entertainment. But I’d like to hear more about how so many species can survive in such an astounding density, according to the narration, only if they all look very different. The feel-good 3-D finale: curious Australian Sea Lions poke their snouts right in your face just like friendly puppies. With Blue Chromis, Cassiopeia Jellyfish, Cardinalfish, Crocodile Fish, Flamboyant Cuttlefish, Frogfish, Epaulette Sharks, Leafy Sea Dragons and Weedy Sea Dragons, Lionfish, Ribbon Sweetlips, Skunk Anemonefish and the Wonderpus Octopus. 40m. IMAX. (Bill Stamets)
