Blue Whale

The largest living mammal on this planet is endangered. The blue whale, rarely seen, roams from the oceans of the north pole to the oceans of the south pole and everywhere in between. Blue whales weigh a whopping 20 tons which is about 33 elephants combined. At birth, a baby blue weigh can be about 25 feet long and by the time they mature they are 100 feet long. They usually swim at a sedate 3-10 miles an hour but are known to swim up to 30 miles an hour when they feel threatened.

Because of it’s size, this beautiful mammal has some of the biggest organs on Earth. A fully matured blue whale’s tongue can weigh about as much as an elephant (6000 lbs) and their hearts are literally the size of your average Volkswagon Beetle automobile which weigh about 3000 pounds. The blue whale also has the loudest call on Earth; 188 decibels. This is louder than a jet engine plane and can be heard by all manner of marine species 1,000 miles away. Turn your volume up and check out this snippet below. Truly mind blowing.

Even though these gentle giants are at the top of the food chain, their diet consists of 4 tons of krill each day. Baby calves drink 100 gallons of milk a day from their mamas and can gain 200 pounds a day! During migration periods, blue whales can go without eating for 4 months because they build huge fat reserves.

Blue whales became endangered due to serious whaling in the early 21st century. It has been estimated that over 200,000 blue whales have been killed leaving the population at about 5000 individuals left. Although whaling has been drastically reduced, blue whales are still at the mercy of climate change and getting caught in fishing nets because their migration path sometimes lands them in fisheries.

The people over at WWF have been placing satellite chips in blue whales they encounter in efforts to track their migration paths in order to establish protected areas that large vessels and fisheries can avoid.

    1. They are too cool! I remember my first book report being about blue whales and I was amazed even then. Can you imagine how long they’ve lived and evolved? Some reports claim that they are larger than the largest dinosaur!


        1. As long as we don’t irreversibly drain all the oceans in some way, they should be fine out in the deeper waters away from civilization.


    1. It really is. Plenty of pictures but I still can’t fathom their size! I bet its exhilarating as hell for a conservationist to see one in their lifetime.


  1. Wow! I’ve always heard that blue whales were huge but your comparisons gave me a greater appreciation for just how big and amazing that are. They’re truly special creatures. Thank you for sharing. 🙂


  2. Wonderful story Nel, I don’t believe I have heard much on the blue whales. WWF is one of greatest protectors of all wild creatures, hopefully they can help the beautiful whales. Thank you for sharing.


  3. Wonderful post Nel! I’m so happy that you are giving such posts and increasing peoples’ awareness about such animals. These are some beautiful animals and we should do whatever we can to protect them. I’m sharing this post on my blog. You don’t mind, do you?
