Baja California, the coast is a haven for sea creatures. This film explains why walruses, fishes and birds flourish here in packs, schools and flocks.

Whales spit through their breath holes, walruses roar, sharks slither, huge manta rays float like magic carpets above an ocean floor hosting life growing upon life.

Starting from a blizzard of plankton, "Ocean Oasis" captures the aquatic food chain in action. The translucent jellyfish and plankton shots are dazzling, like submerged star constellations. Well shot too, a slow-mo hummingbird, canyon palm trees and a single diver tangoing under a giant manta ray twice her size while two suckerfish hitchhike atop.

Fascinating documentary that could have benefited from just a few more "LF moments."
