A tweet has survive viral over the last few Day lay claim that throughout history fishermen have mistake beluga heavyweight for mermaids because of their … human - like knees .

It may be a windup , though the story generally brand facts from history and science . Whether it ’s a windup or not , it appear to have been swallowed whole by tenner of thousand of hoi polloi who have retweeted it .

So allow ’s get the obvious out of the way   – no , beluga whales do not have human - like knee . They do not have legs .

" If you calculate at their skeleton they do n’t even have legs so how would they have knee . dolphin are the same path . The only matter close to this are two diminutive pelvic osseous tissue that do n’t really dish any design . You should really fact check , "   one persontweeted .

" To me it looks like that ’s a beluga hulk that recently had a calf because those swollen looking sections are near the mammary glands . But I ’m not a super expert on if that ’s what that really is but I know for certain it ’s not articulatio genus . "

The last clock time this double of the " beluga mermaid " went viralon Reddit , many mass pointed out that from any other angle they nothing like a mermaid . For example , in this TV of   a beluga whale come out to thoroughly delight being serenade by a mariachi band , there ’s nothing about the puppet that a sailor could misidentify for a part - fair sex , part - Pisces the Fishes .

The " legs " can only be viewed   seen from below , which is not an angle you ’d usually view them from , and only in very rarefied photos . They ’re actually just a conjunction of how the whale’sfolds of fathave devolve whilst the photo was being guide .

" Belugas that are especially well - endue with blubber will show visible ' rails ' along each side of their belly where special adipose tissue is contained,“Travel4Wildlife excuse .

A want of knees , or indeed legs , becomes rather obvious when take care at their skeletal system .

Also , we do n’t want to be a concluded killjoy here , but why on Earth wouldmermaids – which famouslyhave no leg – have knees ?
