Blue Whale

A blue whale (Balaenoptera musculus) is a marine mammal and the largest animal on Earth, both in terms of length and weight. It is found in all of the world's oceans and is known for its massive size and its unique filter-feeding method. 🐋

Blue whales have a long, streamlined body with a mottled bluish-gray color. Their head is broad and flat, and their body has a series of grooves that run from their jaw to their belly. They have a small dorsal fin and a pair of long, pointed pectoral fins. Their tail is a pair of massive flukes, which they use to propel themselves through the water.

Blue whales are found in all of the world's oceans, from the Arctic to the Antarctic. They are carnivores and their diet consists of tiny, shrimp-like crustaceans called krill, which they eat by the ton. They are a filter feeder, using a series of baleen plates in their mouth to strain krill from the water.

Blue whales are generally solitary animals, but they may form small groups to feed. They are known for their loud, low-frequency vocalizations, which they use to communicate with one another over long distances. Once hunted to the brink of extinction, the blue whale is now protected by international law.
