Just read this depressing news. Cause of death is still unknown.
Philippine town mourns largest captive crocodile - Yahoo! News
He did live there for over a year, and I'd like to think that they did all they could to take proper care of him. I wouldn't be surprised if his death was simply due to old age, given his immense size. It's truly a shame to lose such a magnificent creature regardless, but at least there is hope that others like him (possibly even larger) still survive in the region, and hopefully his story will inspire the people to keep the area preserved for future giants to live.
Really Lolong was such an inspiring animal. Before him I had kind of given up hope of seeing such a immense crocodile alive, but his existence showed that historical giants are still out there, perhaps even recovering in some areas from all the hunting pressure. I still may never see such a creature in person, but it was amazing to see the films and photos regardless, for once a animal whose size did not need to be exaggerated.
