Snake!
Again, snakes congregate at sea. Well, certain snakes, that is, but you never want to find yourself within arm’s length of a sea snake if at all possible. This guy had just resurfaced and heard shouting from the others. Apparently, he had resurfaced at the exact same moment as a sea snake did.
Just so you know, most species of sea snakes are highly venomous, but the majority of their bites on humans very rarely inject venom. But if we were in this guy’s situation, we wouldn’t like to play the odds, especially since even a tiny bit of their venom can kill as many as eight people!
