Amazing Facts About Whales!

Are you looking for some of the most mind-blowing facts about these awesome marine mammals Oh whale whale whale you've come to the right place 

    When we say Wales we're talking about the order of animals called cetaceans which are further divided into two subgroups toothed whales and baleen whales despite living their whole lives in the water whales are in fact mammals they give birth to live young they nurse with milk and they're warm-blooded they even have hair before they're born whales are covered in a layer of fuzz called lanugo and some even keep hair as adults now like all mammals and other tetrapods whales are descendants from ancient fish that crawled out of the water about 375 million years ago but for some reason cetaceans turned around and crawled right back in the ocean about 50 million years ago and what's now Pakistan four-legged wolf sized creatures began to hunt in the water and over time evolution selected for traits that help them in their aquatic lifestyle.
     Cetacean nostrils gradually migrated back from their snout on top of their head where we find them today baleen whales still have two holes up there while toothed whales only have one blow because whales descended from animals with limbs under their bodies their backbones don't naturally Bend side to side but rather up and down and that's why their tail fins are horizontal instead of vertical like fish and even though they no longer have hind limbs their hips aren't completely gone in some species ves Digital pelvic bones are now used to anchor the penises of male whales okay then since they evolved from land mammals it's no surprise that whales still have ears but because of their deep diving lifestyle they no longer have these floppy things to funnel sound and their ear canals are no longer open to the outside but a lifetime is worth of ear wax still builds up inside scientists can harvest these ear plugs from dead whales and use them to study the diet and hormone levels every year that whale was alive just like really gross tree rings 
    Toothed whales like dolphins and sperm whales use echolocation to hunt and navigate clicks May then the nasal passages are focused by a massive tissue in their forehead called the melon and fatty tissues in their lower jaw pick up the returning echoes and deliver those vibrations to the inner ear baleen whales like humpbacks don't use echolocation but are famous for their negative humpback whale songs are incredibly complex with short phrases combined to the themes that are mixed into songs each lasting half an hour or more they're like blubbery Beethoven's we're still not exactly sure how whales like humpbacks make these singing sounds but scientists think they might use this big sack under their vocal cords to squeeze air through the larynx kind of like a bagpipe and then recycling it into their lungs so they don't waste a breath whales are technically carnivores and he just about every kind of animal there is in the ocean toothed whales like orcas porpoises and sperm whales eat everything from fish to squid to seals while baleen whales use their bristly namesake to filter small animals like krill and plankton and even fish from huge gulps of water now when Warhol whales like call backs fin whales and blue whales sense food ahead their mouth opens almost 90 degrees and they're split lower jawbone spreads wide like a fishing net as they close their mouth their giant tongue squeezes the water out through the baleen filter leaving those tasty yum Yum's behind other baleen whales like bowheads don't open their jaws as wide but instead ram up to 3,000 litres of water per second out the corners of their mouth as they filter out dinner 
    No whale is as weird as the narwhal a contrary to popular belief they are not unicorns wearing specially designed scuba suits these huge tusks usually found only on males are actually elongated canine teeth sticking right out the front of their foreheads they don't have any teeth in their mouths but those things more than make up for it now no one agrees exactly what the tusks are for but some scientists say it's a sensory organ while others say it's just for males to attract females but that doesn't really matter because they're awesome the inuit even made harpoons out of narwhal tusks tipped with iron from a meteorite you kidding me a blue whale can eat as much as four tons of food in a day and what goes in must come out when it comes to poop whales go big they often feed in the deep ocean and their poop brings those nutrients up to this where they act as fertilizer for shallow ecosystems it's estimated that sperm whales and the iron in their poop help sequester 200 thousand tons of carbon from the atmosphere every year by fecal e fertilizing photosynthetic plankton whales set some amazing records to the deepest diving species Cuvier x' beaked whale has been tracked to 3,000 meters below the surface and some bowhead whales have been found with harpoons dating from the 19th century still embedded in their bodies this lead scientists to estimate their lifespan at up to 200 years finally like all animals whales eventually die when whale carcasses sometimes weighing more than a hundred tons fall into the ocean's dark depths they can form mini ecosystems called whale Falls sustaining countless deep-sea species for decades strange creatures like these zombie worms devour everything from the blubber to the bones I hope you enjoyed this fact
