Whales can weigh from 270 kg (Dwarf Sperm Whale) to over 180,000 kg (Blue Whale). ü The Grey whales migrate over 10,000 miles a year. ü Sperm whales can hold their breath for up to 90 minutes. ü Humpback whales sometimes make fish-catching nets by blowing bubbles. ü A single adult Blue whale is capable of consuming about 4 tons of krill a day. ü Blue whales have an average lifespan of 80 to 90 years in the wild. ü The snouts and backs of grey whales look like a crusty ocean rock as they are often covered with parasites and other organisms. On this years’ World Whale Day, join hands to celebrate for these giants of the ocean to raise awareness of these magnificent creatures, their beauty as well as their ecological value to the planet. Happy World Whale Day!
