Gladiator spiders build a net and hold it with their front legs, and when prey stumbles into just the right spot, the spiders cast the net over the victim and then pounce. Lunchtime!

Here, kitty kitty. Jaguars are headhunters. Unlike a lot of big cats that go for the throat, jaguars cut to the chase and aim for the heads of their prey, in an effort to cause instantaneous death.
