RE: Venomous Snakes - parvez - 10-14-2016
I have a question here. Does the venom help in digestion of food also or its lone purpose is to kill the prey? Please anyone answer Thanks

As far as I know, no.
The purpose is to outright kill or at least paralize the prey.

Thanks for the reply. I too was thinking the same. But somehow got too curious on it for some reasons.

@parvez:
About #61: The snakes' venom has a double utility: At first in order to kill the prey. Then, in order to help the digestion. More the gastruic juices are concentrated, more the venom are efficient. And vice versa (reciprocally)...

@Spalea thanks for the reply. Do you mean the venom is formed from the same substances as gastric juice? Are they chemically the same? I do not think so. If you do not mind can you show me the sources. Thanks again,

@parvez:
Venom and gastric juices are not formed with the same substance. Their roles complement each other. Here you have an explanation:

Thanks @Spalea I forgot the fact that poison glands are modification of salivary glands which aid in digestion. Now i completely understand the fact. Thanks again.

Is it true that snakes do not eat dead food? They only eat the prey which they have killed. I have heard that they do not eat the dead prey from many people. Please anyone reply if it is true or false?

I believe that is logical... Venom and gastric juices are needed for the digestion, but the snakes needs to kill the prey it want to eat. If the prey is already dead, the venom (logically helping the digestion) cannot be injected into the corpse because it will not be able to flow inside the body (blood circulation out of order). If the venom is useless, so are the gastric juices useless for the digestion.
In short, snakes need to kill their prey, to feel the heat of the prey's body.
And the snake cannot afford to waste the venom which is precious.
That is why in the zoo, living animals (mouses or rabbits) are always given for the snakes' meals... When the visitors are gone.

Thanks for the reply @Spalea and great explanation and logic as well
. So, you believe that unless venom is not secreted in some way or injected into the body its digestive system does not get activated? That is an interesting process. I have read that venom gives digestion process a kick start. And also according to your assumption unless when the snake does not feel the heat of the body of prey it's digestive system does not get activated. That is some long and interesting process also considering the fact that snake is an ancient animal. We need to get more confirmation from experts on this topic. We can have more information on the digestive systems of venomous animals or ancient animals in general. Thanks again spalea

I am in contact with experts, I am in interesting conversation with them, I will post the details here after i get confirmation on all these things about venomous snakes.

Types of venoms in poisonous snakes,
1.Neuro toxins,
2.Cytotoxins.
Neurotoxins: These are the toxins that are poisonous or destructive to nerve tissue that cause neurotoxicity. These are an extensive class of exogenous chemical neurological insults that can adversely affect function in both developing and mature nervous tissue. They typically affect the respiratory centre there by causing death due to blockage of nerve impulses that regulate respiratory system. Those humans or animals that survive these attacks do not have any sequelae (after affects of snake bite such as tissue damage). They act through various mechanims.
(A) Blocking the nerve impulse transmission,
(B)Inhibiting the ion channels,
©Receptor inhibitors,
(D)Blood brain barrier inhibitors,
(E)Multiple or combined effects
Cytotoxins: These are the toxins that specifically attack tissues or muscles. They act through various mechanisms that damages the cells either by rupturing cell membrane or through blocking muscular depolarisation thereby inhibiting muscular contraction. Accordingly they are classified as,
(A)Hemotoxins that cause the damage to the RBC or induce blood coagulation
(B)Cardiotoxins that attack heart causing depolarization of cardiac muscles
©Phospholipases that rupture cell membrane through certain processes.
