Watch researchers remove a sea lion's head from this shark's stomach

No, you did not misread that headline. Yes, this video is incredible. Shark stomach. Sea lion head. What else do you need to know?

The organs of a 1300-pound Mako shark – one of the largest ever caught! – were recently donated to a research facility operated by NOAA. In this video, fisheries biologist Antonella Preti dissects the shark's stomach, only to discover that its last meal was a whole seal.

Gut analyses like these give researchers an idea of which animals are eating eachother in the ocean, making it easier to manage the conservation of fisheries and other ecosystems. They're also utterly captivating, if you're into this sort of thing. My favorite part (apart from the seal head, of course) is when Preti lifts the stomach lining from the Rubbermaid tub, its folds pleating like a wet towel, and compares it to "a blanket, pretty much." LOVE IT.


Watch it. You'll love it, too. And if you're into this sort of thing, you'll definitely dig this.

I watched one of those "Shark Week" programs last night. There's apparently a species called the "Greenland Shark", that swims around in the waters between Iceland and Greenland. Opening one up, it's stomach contents consisted of horse, caribou... & polar bear.
