Method of the mussurana’s attack upon the jararaca.

Note the size difference between the two snakes. The mussurana is able to consume comparatively large snakes because its digestive system compresses the body of the other snake into a wave-like shape.

Here’s a jararaca! I’m still gonna find that other one, whether it wants to be found or not…

(via Computer virus hits US Predator and Reaper drone fleet)

A computer virus has infected the cockpits of America’s Predator and Reaper drones, logging pilots’ every keystroke as they remotely fly missions over Afghanistan and other war zones.

The virus, first detected nearly two weeks ago by the military’s Host-Based Security System, has not prevented pilots at Creech Air Force Base in Nevada from flying their missions overseas. Nor have there been any confirmed incidents of classified information being lost or sent to an outside source. But the virus has resisted multiple efforts to remove it from Creech’s computers, network security specialists say. And the infection underscores the ongoing security risks in what has become the US military’s most important weapons system.

“We keep wiping it off, and it keeps coming back,” says a source familiar with the network infection, one of three that told Danger Room about the virus. “We think it’s benign. But we just don’t know.”

Military network security specialists aren’t sure whether the virus and its so-called “keylogger” payload were introduced intentionally or by accident; it may be a common piece of malware that just happened to make its way into these sensitive networks. The specialists don’t know exactly how far the virus has spread. But they’re sure that the infection has hit both classified and unclassified machines at Creech. That raises the possibility, at least, that secret data may have been captured by the keylogger, and then transmitted over the public internet to someone outside the military chain of command…

Lion Claw.

Lion paws have an extra joint compared to other cats, and this gives them extra range-of-motion. Thanks to this additional range, lions can sink their claws deeper into prey than any other mammal, and they can hang on through a huge amount thrashing and struggling. Their broad pads that allow for silent movement also provide a huge surface area to back up a swipe with the claws, and combined with the massive forebody muscling, this allows lions to deliver a blow strong enough to break a zebra’s back.

The Hand; its Mechanism and Vital Endowments, as Evincing Design. Sir Charles Bell, 1854.
