Whales and Dolphins
Whales and dolphins are some of the most well-known aquatic mammals, with over 80 species identified worldwide. These cetaceans are characterized by their streamlined bodies, powerful tails, and advanced brain structures. Whales and dolphins are found in oceans across the globe, from the Arctic to the Antarctic, and are capable of diving to great depths in search of food. One of the most notable characteristics of whales and dolphins is their highly developed social behavior. Many species of whales and dolphins are known to form close-knit groups, with some populations exhibiting complex communication patterns and even cultural behaviors. However, their social behavior also makes them vulnerable to threats such as habitat disruption, noise pollution, and entanglement in fishing gear.Seals and Sea Lions
