venom question?

Post  Admin on Thu May 03, 2012 5:01 am

Venomous snakes possess one of the most sophisticated weapon systems in the natural world,we must all agree on, venomous snakes don't possess limbs to chase down there prey,or claws to hold on to it, but non of this really matters as evolution handed snakes the ultimate weapon,My thought is, is it safe to say that the venom needs to evolve to be more effective to keep up with the prey items. Chemicals and toxins are constantly being introduced into our ecosystem.And with this in mind many prey items must build up a resistant to those toxins/venom over time for survival.For example, in the past, ive heard of certain rattle snakes that generally produced hematoxic symptoms in there prey but certain changes over time that hematoxic effect seems to be losing many of its hematoxic properties and becomeing primarily neurotoxic ? Is it that snakes learn that their venom is not that effective, so their body will automatically tweak it to be the most effected against all ?

It might be more a case of that the more we study venom composition, the more we realise that venom types are not as simple to define as once thought. Different species process different combinations of proteins and toxins within their venoms. A snakes' venom composition can noticeably change as snakes grow and mature.

Would you be able to give some examples of the compositional changes that occur as snakes get older citing specific species if known? I am a bit of a venom junky and enjoy learning the specific aspects of venom and its properties so I would be very interested to hear the results.
