Whale Biology and Behavior

Whales are the largest animals on Earth, known as the giants of the ocean. They are air-breathing mammals, with females nurturing their young with milk. There are two main types of whales: baline and toothed. Baline whales, like humpbacks, filter feed on krill, while toothed whales, such as orcas, hunt fish and squid. Whales are also famous for their songs, which can travel miles underwater, though the purpose of these songs remains a mystery. Due to past hunting, whale populations have declined, highlighting the need for conservation efforts to ensure their survival and the health of ocean ecosystems.
