Megalodon

C. megalodon is a prehistoric Shark from the Mesozoic to Cenozoic era (Only Cenozoic in places other than the Southern Ocean) that lived approximately 100.5 million years ago to the present day (in other places from 28-1.5 million years ago) at a maximum length of 67 feet. It is a deadly predator, being the largest species of shark known. It is possibly a close relative to the great white shark (Carcharodon carcharias). One is frozen inside of the Iceberg to this day, although the ice of the Iceberg to too thick and snow covered now to see it.

Trivia

 * It still exists to this day in Club Penguin
 * One was sighted by Rockhopper and described to be the size of his boat, meaning it was a 40 ft. long sub adult.
 * In Club Penguin they evolved much earlier then anywhere else in the world, as they were sighted in the Late Cretaceous period.
 * It is so large that it preys on whales.
 * If you look closely, part of it is outside of the Iceberg, similar to how the Iceberg jots down in the water.
 * This may mean it will unfreeze soon.
