I don't believe there has been any research on this subject. In my experience with 100's of burms, hatchlings have a much stronger "fight or flight" reflex which means that they are quicker to strike and do so with more gusto. Strikes from large adults are usually designed to scare off offenders and as such, are not always intended to hit their target which equates to a slower but more deliberate strike. BUT, when it comes to feeding time, a large burm can and will strike with as much speed as a hatchling.

>>My snakes are 10 and 13ft. Both are perfectly fine most of the time..Feeding time changes things but thats expected.
>>I was under the impression we were discussing the speed of the strike on baby vs adult snakes...thats all i was talking about
