So, you already knew that there are approximately 420 species of shark classified today and that new species are still being found. And you already knew that the Great Hammerhead Shark grows up to 600 cm in length, can swim to a depth of 80 metres, has been known to give birth to up to 42 young and that its Latin name is Sphyrna mokarran. Oh, you really did? Well in that case, you've already got Sharks Top Trumps. Congratulations!
