Here are some facts about blue whales

  • The record appears to be at least 110 feet long and a weight of 209 tons (It was a female)
  • Average Length: (Male) 82 ft (Female) 85 ft (Birth) 19 1/2 ft
  • Average Weight: (Adult) 100-120 tons (Newborn) 2.5-4 tons
  • Population: 2,000 -3,000
  • Diet: Krill and Fish
  • Range: All oceans of the world
  • Lifespan: More than 80 years
  • Threats: Loss of food, pollution
  • A blue whale drinks 50-150 gallons of milk a day, adding about 8 pounds of weight per hour, or 200 pounds a day
  • At about 8 months of age, when the calf is weened, it can measure close to 50 feet long and weigh about 50,000 pounds
  • At sea, blue whales usually feed alone or in pairs, often widely spaced
  • A blue whale's "blow" can reach as high as 30 feet!
  • During the feeding period, a blue whale can ingest 4 tons of krill a day. They feed at the beginning and the end of the night at a depth of at least 130 feet (40 m).
  • Pre-whaling population estimates were over 350,000 blue whales, but up to 99% of blue whales were killed during whaling efforts
  • Blue whales have no known predators (other than humans during the whaling years)
  • By the 1950s, blue whales were endangered
