I know everyone has their own conscious/unconscious biases towards certain pets that they own.
I have a large number of ball pythons. I can tell you that there are always exceptions in any specific morph/line.
If I stack up the number of times I have been bitten defensively/aggressively relative to the number of snakes of a comparable morph. I can tell you that the Spider Morph has easily given me the most trouble. The Morph itself is known to be linked to neurological issues and while only a small percentage of mine actually show 'wobble' when feeding...A lot of them still behave erratically when disturbed.
