The same team who made IMAX's Into The Deep visit some of the world's most remarkable and inaccessible sea life. Take the 100-pound Humboldt squid, a dangerous predator that changes colour four times a second, filmed in the Sea of Cortez off Mexico. Or the rainbow nudibranch, a sea slug who eats poisonous tentacles and regrows them through its own back. Intimate shots, aided by IMAX's stunning clarity, capture the alien beauty of these creatures, and many more, in utterly convincing three dimensions.
