Unfortunately, no… I’ve seen one of those things, and they’re honestly kind of scary to stumble across in the wild. They’re huge, and they can swim.

I do agree that this picture looks weird, but I think it’s just a weird picture. The spider is hanging backwards, with his belly facing upwards (that little nubbin at the back of the abdomen usually angles down), but the way that he’s lifting his head to bite the turtle makes it look like his body is facing the other way. As for the ripples, it looks like he’s lifted the turtle high enough that we’re getting a shot of them without the water directly below them. The ripples look like they’re probably relatively calm water 5-10ft behind the spider, which is why they don’t match up with the action in the photo.
