The Carcharodon Megalodon Super-Shark

The Carcharodon megalodon super-shark swam in the oceans more than a million-and-a-half years ago. It grew up to 16m (52ft) in length and weighed in at 100 tonnes - 30 times heavier than the largest great white - and must have been one of the most formidable carnivores to have existed. "Pound for pound, your common house cat can bite down harder, " explained Dr Stephen Wroe of the University of New South Wales, Australia. "But the sheer size of the animal means that in absolute terms, it tops the scales."

By looking at the distribution of stress and strain on the sharks' jaws, researchers found that the largest great whites have a bite force of up to 1.8 tonnes, three times the biting force of an African lion and 20 times harder than a human bites. Megalodon, though, is more impressive. It is estimated to bite down with a force of between 10.8 to 18.2 tonnes. The team said biting with such force was quite a feat given that the jaws of these ancient creatures were made of flexible cartilage. In contrast to most other fish, sharks' skeletons are made up entirely of cartilage. Scientists think that cartilage, being a much lighter material than bone, is one adaptation that allows sharks to swim without the aid of a swim bladder.

A recent BBC series imagined a face-to-face encounter


Kalau betul ada menatang nih mesti best kalau dapat tangkap gambar... besar yang amat... klau nak amik gambar pun kena zoom jauh2 baru dapat gambar penuh ikan tu.. tapi gambar orang tak clear sebab nampak ciput je di sebelah ikan...

P/S: Klau terserempak konfom muka dah xda darah hehe...


  1. wahhh...dah jadi ahli zoologi ka skrg?...

  2. hahaha... lepaih ni nak kaji pasai kura2 pulok... tak rela akak aih hehe grau je...

  3. Gambor orang dalam sangkar tu betul ke? Material apa depa guna nak buat sangkar tu? Mesti kuat gila sebab kekuatan gigitan megalodon tu 18.2 tan! Sangkar haper yang boleh tahan tu?
