Cetacea

Cetacea is the scientific group that includes all whales, dolphins, and porpoises. These marine mammals are known for their adaptations to life in water, such as streamlined bodies, flippers, and the ability to hold their breath for long periods. Cetaceans are divided into two main groups: baleen whales, which filter feed on small organisms, and toothed whales, which hunt fish and squid. They are highly intelligent and communicate using vocalizations. Cetaceans are crucial to marine ecosystems and face threats from human activities, making their conservation an important issue.
