Marine mammals include cetaceans (dolphins, whales), which live in the sea from birth to death, and pinnipeds (seals, fur seals), which breed and rest on land but feed in the water. As top predators in the marine ecosystem, marine mammals influence the ecosystem through feeding on their prey, and also live under the influence of environmental changes. They also have various relationships with us humans and interact with us. Through our research, we think how the oceans where we live with them can continue to exist in the future.
