Blue whale

About Blue whale:

• Blue whales are the largest animals ever to live on our planet.
• Whales are at the top of the food chain and have an important role in the overall health of the marine environment.
• Habitat: They are found in all oceans except the Arctic Ocean.
• They generally migrate seasonally between summer feeding grounds and winter breeding grounds
• Lifespan: The average lifespan is estimated at around 80 to 90 years. Scientists can estimate the age of whales by counting the layers of wax-like earplugs collected from deceased animals.
• Behaviour and Diet
  • They sometimes swim in small groups but are more often found alone or in pairs.
  • They generally spend summers feeding in polar waters and undertake lengthy migrations towards the equatorial waters as winter arrives.
  • The primary diet whale is krill—tiny shrimp-like animals, but fish and copepods (tiny crustaceans) may occasionally be part of the blue whale’s diet.
• Conservation Status
  • IUCN: Endangered
