  1. Growing to one-hundred feet long and weighing up to 200 tons the blue whale is the largest animal to have ever lived on earth. Their tongues can weigh as much as an elephant and their hearts as much as a car!

  3. A healthy adult blue whale can live for 80-90 years.
  4. The blue whale can eat as many as 40 million krill per day or around 8,000 lbs. daily in order to power its massive body.
  5. Except for occasional but still quite rare attacks by pods of killer whales on very young and small individuals, blue whales are not known to have any natural predators. Sri Lanka 6 (2)

Recovery remains slow for this magnificent and iconic animal but rebounds in the Eastern Pacific population of blue whales (returning to an estimated 97% of historic pre-whaling levels) indicate promising trends. While numerous threats remain, especially strikes on animals by passing ships, the now healthy and sustainable number of whales that traverses the waters from Northern California to Costa Rica indicate there is hope that the amazing and beautiful blue whale will recover globally as well.
