I've always found emperors easy to handle.
Pick them up by the tail and slide a hand underneath and they'll sit there quite happily. Try not to breath on them, they are covered in very sensitive hairs and they don't like it very much.
There are LOADS of videos on youtube, one I saw though the woman just shoves her hand underneath the scorpion from the front, which is really just asking for trouble. Some others you'll see people stroking the back of the scorpion, again really wouldn't recommend this, at least not without the other hand holding the tail!
But as is the case with handling most inverts- just because you CAN doesn't mean you SHOULD.
Oh, one bad thing about emps- they do not kill small insect pray before eating it, and its pretty gross watching an alive cricket getting eaten bum first while its still trying to run away!
And you can hear the 'crunch crunch crunch' as well.
Of course, when baby emps are running around with faces stuffed with half eaten crickets its simply adorable :flrt:
