Balinalar, or whales, are large marine mammals belonging to the order Cetacea. They are known for their impressive size, with some species, like the blue whale, being the largest animals on Earth. Balinalar are found in oceans worldwide and play a crucial role in marine ecosystems. These creatures are divided into two main groups: baleen whales and toothed whales. Baleen whales, such as the humpback whale, filter food from the water using baleen plates, while toothed whales, like the sperm whale, hunt for fish and squid. Balinalar are also known for their complex social behaviors and communication skills.
