Main activities in the Deep Sea Hunting Prey (Deep-sea Foraging): The Deep Sea (depth 200–1,000+ meters) is where whales look for food. Mother whales dive to hunt giant squid, deep sea fish, or krill. Although the baby whales are still breastfeeding, they are starting to learn to recognize the way their mother tracks their prey. #SeaCreatures #MarineLife #OceanLife #SaveTheWhales
