Sadly, Lolong the record-breaking 6.17 m saltwater crocodile caught in the Philippines in September 2011 died last night around 8 pm local time. There's a lot of speculation about the cause of death, but until a necropsy has been completed, we won't actually know what killed him. Ronnie Sumillar, the local expert who led the capture effort, is conducting the necropsy. I'm sure this is not what he wanted to be doing today.
I'll write a more detailed post when more has been confirmed.
