Making up 71% of planet earth, this biome dominates the world. From shallow, warm water to cold, lightless depths - the Ocean. With much life left to be discovered, oceans are home to some of the world’s deadliest creatures. Silent and assuming, Sea Urchins litter the sea floor, armed with a lethal sting. A large, predatory fish swims through the water, the Barracuda. Floating peacefully through the sea, the Portuguese Man O’ War - a jellyfish armed with a devastating sting. Hunting in pods, these mammals are highly intelligent, with a fear inducing nickname - Killer Whales. These are the WILD ASSASSINS of the Ocean.
