Marine Life Encyclopedia & Field Guide
Marine Life encompasses the breathtaking spectrum of organisms inhabiting Earth’s saltwater oceans—from secondarily adapted marine mammals (whales, dolphins, seals) and hyper-intelligent cephalopods (octopuses, squids, cuttlefish) to stinging cnidarians and benthic crustaceans. Covering 71% of Earth's surface, oceans harbor the highest phylogenetic diversity on the planet.
