Relative toxicity of scorpions


I'm going to quote figures straight from articles (some require some calculations to give the same LD50 reference) so draw your own conclusions. Please read the section on 'other points to note' to help you interpret the results. From this table alone, much can be learnt.

The animals listed for comparative study are

This list of scorpion LD50 is ,by far, the longest I know on the net.
