Hi there!

Can some one please assist? What venom does the Psammophis-family have? I understand that has no medical interest as these snakes seems not to hold any danger for humans, but they must have some sort of venom as they have fangs?

Thanx for the hyperlink. I am making an assumption based on all the information I have that the poison of this family is cytotoxic as some of the symptoms are swelling and local pain. As far as I can gather that is the symptoms of cytotoxic venom.

Neurotoxin also has swelling and local pain ;)

With Cytotoxic, it has swelling and local pain and the skin around the bitten area will slowly start peeling away and almost ass if a drop of acid has been dropped on the area.

Its not pretty, i have been bitten by a Sac Spider and had to be rushed to hospital because my whole arm started getting the effects of the Cytotoxin ;)

Okay, I agree neurotoxic might be the better call, as nausea is also one of the symptoms. :) One thing is for sure we can agree it is not hemotoxic. At least this will help with the project that we are working on. What did you to get bitten by a spider?

I have also been bitten by a sac spider and agree with Batmad - not funny at all! Fortunately, I managed to avoid having to go to a hospital, but just! (Still have the scar - read indentation - to prove it)

Fortunately we have not had a spider bite in the family. However my son was bitten by a male Uroplectes olivaceus (scorpion) about two and half weeks back, and there is still a mark - small but it is there. We are looking at snake venom for a science project my eldest son is busy with, learned alot about snakes in this period. Properbly next year we will be doing the project on either scorpions or spiders.

9 or 10 species of Sand Snakes are known to be found in Africa and Southern Asia.
Although venomous is not dangerous to man.
These animals very seldom if ever bite in defense.

Firstly I prefer using the common name with the scientific name as a reference = Eastern Tiger Snake
(Telescopus semiannulatus semiannulatus).
When I am talking with people regards snakes I try speak english because most of us don`t refer to Latin till there is a discrepancy in subspecies or we are discussing specifics.

The venom is of no consequence to humans but I see that this particular critter was discussed on this site some time back. viewtopic.php?t=4922

Hi Predator

Take a look at this topic from sareptiles.co.za

http://www.sareptiles.co.za/forum/viewt ... 61&t=11892

Seems someone was asking the same question as yourself

Thanx! I had a look at it, wow! My son(gr6) completed a project on snakes recently and what was interesting was to see, it seems like their is a relationship between the snake's prey, venom and even teeth.

The more you look at snakes the better you begin to understand them and see how they fit into the environment as a whole.
Looking at a comparison like this does make sense in terms of dentition and venom matching the particular prey species.
Sounds like a really good project for him, enjoy it and keep learning
