Cetaceans are a diverse group of marine mammals that are well-adapted to life in the water. They include whales, dolphins and porpoises. Cetaceans have streamlined bodies, which allow them to move efficiently through the water. They use flukes (tail fins) for propulsion. Despite being marine mammals, cetaceans are air-breathing creatures. They possess blowholes on the tops of their heads, which they use to surface and breath. It enables them to remain underwater for extended periods, varying depending on the species. Key features include their complete adaptation to aquatic life, frequently substantial size, and strictly carnivorous diet. There are over 80 recognized species of cetaceans, this includes the largest animal on Earth, the blue whale. | |||
Cetaceans exhibit a wide range of feeding behaviors and diets. Some species are filter feeders, consuming tiny plankton and small fish, while others are active hunters, capturing larger prey like fish and squid. Cetaceans play crucial roles in marine ecosystems, influencing prey populations and maintaining the balance of marine food webs. Many cetacean species are migratory, traveling long distances between feeding and breeding grounds. Often cetacean species are highly social and live pods or schools. These groups can range in size from a few individuals to several hundred. | |||
Cetaceans have been the target of extensive hunting for their meat, blubber, and oil by commercial enterprises. They therefor hold cultural and economic importance for human communities around the world. | |||
