BABY Shark is being blasted over factual inaccuracies by boffins on the internet.
Several Twitter users have taken to the site to point out the various ways the ear worm has got biology wrong.
Podcaster and Qi researcher James Harkin pointed out that grandma sharks are unlikely to be found in the wild owing to their lifespan and the age they can reproduce.
He tweeted: “Female great white sharks don’t reach sexual maturity till they’re in their mid-30s and max lifespan is around 70.
“So actually, I don’t think grandma shark is really a thing.
He added: “Basically grandmas aren’t very common in nature. Except notably in humans and killer whales.”
Aussie PhD student Shannon Lauchlan also chimed in to say that it was not just the lyrics that were inaccurate but also the dance moves.
She wrote: “Typically female sharks are larger than male sharks (#SexualDimorphism).
“So mummy shark should really have the the bigger bite.”
In the actions that go with the tune the “mummy shark’s” bite is signified by clapping the with the hands kept close together.
Whereas as the “daddy shark’s” bite is illustrated by full arm swings bringing the hands together to denote the beast’s big bite.
She further pointed out that in some instances there would be no need at all for a daddy shark.
The student tweeted: “sSme shark species can reproduce asexually, so then there is no daddy shark #shark #facts #babyshark”
This is not the first controversy to swirl around the song popularised by Korean YouTube channel Pinkfong.
Baby Shark became embroiled in a sexism row in South Korea over the lyrics used in the native version of the tune.
Unlike the English language version of the song the Korean lyrics brand the mummy shark “pretty” and the daddy shark “strong”.

The Kyunghyang Shinmun newspaper said in a front page editorial that the lyrics reinforced sexist prejudices.
