Oh what a beautiful flower that is. Oh hang on, that doesn't look quite right...
No, what you're actually looking at in the amazing video below is the papillae inside a Loggerhead turtle's throat.
While it's slightly gruesome, it's also quite incredible. The papillae are covered in a mucus that enables the turtle to filter out anything that's inedible; either invertebrate shells, or actual rubbish in the sea. It's sort of like the villi in human digestion, only much larger scale (and looks like a Sarlacc from Star Wars).
The footage was taken as part of a Loggerhead necropsy at the Woods Hole Oceanographic Institution; something of a treat for the team, as Loggerhead turtles are an endangered species. We assume/hope the turtle died of natural causes first.
If you've got the stomach for it, there are a few more photos from the procedure below (and more here). But first, here's a gif to watch one more time.
