Even if that particular picture was AI (I don't think it is), there is nothing surprising or exaggerated going on here. More like it's a rather rare/undocumented behaviour. Bit it's totally within the capabilities of a fishing spider.
Yeah I’ve looked a bit harder and I see the spider shape a bit better now (from underneath), the slight motion blur in places would suggest not AI but I’m not totally convinced. From a quick search these spiders aren’t that big so that must be a very baby turtle, and I don’t know what’s going on around the mouth but it doesn’t look right, nor does the interference pattern of the ripples.
Agreeing with me would make a lot of people a lot more comfortable 😅
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.
