There's a new PBS Eons. This one is about Sperm Whales and the fearsome shark Megalodon... who would eat who?!?
Unlike in fiction, giant whales do not emerge fully-formed from the ocean deep. So, where did Livyatan melvillei come from? How did such a large predator live? And what caused the titan to die out? The answer may lie in an appetite so large, it may have eaten itself to extinction...
