A 1,500 pound, 16 foot saltwater crocodile called Rex eagerly devoured a sizable portion of beef ribs on Wednesday, his first feed after emerging from three months of hibernation at the WILD LIFE Sydney Zoo in Sydney, Australia.  

In the winter, it is common for crocodiles to enter a period of inactivity where they survive on the existing energy stores inside their body, but once the weather starts warming up, so does their appetite.
