Yeah. They exist. Here is the only video clip of one. It is dramatically slowed down. It shows the reaction of the Fast Loris just before attacking its prey. (The cameraman did not survive)
Many a fast loris has been mistaken for a drop bear. Understandable, given the limited amount of time to judge such things before the inevitable end.
The claim that there is a terrifying Fast Loris implies the existence of a terrifyingly Slow Loris. I dread the latter vastly more than the former, your concerns be damned.
Haunting and exhilarating
Fun fact: slow loris was also the name for a really cool type of denial of service attack that would eat up the entire connection pool for a linux web server.
