Which is more poisonous a lionfish or a stonefish?

Question

Any help would be nice

Answer 1

A stonefish is more poisonous  

Answer 2

Stone fish; no contest.

Both of them are quite closely related members of the family Scorpaenidae.  While a lion fish can cause a great deal of pain to anyone unlucky enough to get stung by one, there are seldom any further complications beyond the initial discomfort.  

The two species of stone fish can cause a wide range of problems ranging from localized tissue damage and shock, to paralysis and death.  Even surviving a sting from one of these guys can months of surgical procedures and rehabilitation to regain the use of the area affected.
