scorpains arent immune to their own venom, weird aye.
i used to keep em and one stung itself and died.
wen ya think about it, it might not be the venom that kill them, mabey the sting hit a sensitive part of the body. i could be wrong though.
Yeah spiders are supposed to do the same thing (in Reptiles Australia Volume 1 Issue 2, its mentioned that spiders preping to shed are often mistaken as dead). Apparently yabbies remain motionless too (I found this out AFTER I fed a new "dead" yabbie to my fish :lol: )
