Please help with an ID for this snake. It was in Gardenia Hide near Berg n Dal in the Kruger Park in July.

This is not the harmless version of the snake family :shock: . It is definitely a boomslang / Dispholidus typus and they can be differentiated from the harmless green snakes by the shape of the head and the eye. The green snakes (green water snake, natal green snake, spotted bush snake etc.) have a slightly more elongated head, and both the bushsnake and the natal green snake have orange irises, making the eye very unique and easy to seperate from the boomslang's eye. This is most likely a male, as the females are normally (not always) brownish.

Venom

"Many members of the family Colubridae that are considered venomous are essentially harmless to humans, because they either have small venom glands, relatively weak venom, or an inefficient system for delivery of venom. However, the boomslang is a notable exception in that it has a highly potent venom, which it delivers through large fangs that are located in the rear of the jaw.[1] The venom of the boomslang is primarily a hemotoxin. It disables the blood clotting process and the victim may well die as a result of internal and external bleeding.[1][4] Other signs and symptoms include: headache, nausea, sleepiness and mental disorders. Because the venom is slow to act, symptoms may not be manifest until many hours after the bite."

Saw this road kill in KNP near Bateleurs camp :(
Could it be a female Boomslang?

Hi,
this pic wasn´t taken at sanparks and I put it in here because I think that´s my best chance to find out what kind of snake it is.
These snakes were living in a hole in the ground under a shrub. This was in our bush camp in the Masai Mara. In the sunny hours the snakes came out to hang around in the shrub and seemed to be very relaxed if you came close to them. The staff of the camp said they are harmless (some kind of grass snake..), but I´m not to shure about that :hmz:
Could anybody of the experts please help me?

Thanks RosemaryH, that is exactly what I was afraid of :slap:
Anyway, I think I have learned my lesson from this story...

My thoughts on the variegated bush snake are that being a juvenile, the eye seems bigger in proportion to the head. I have read that the boomslang does not have the orange colour around the iris. Also the head from the side is much more chisel shaped than the oval shape of the boomslangs i have seen. But i am certainly no expert either.

Here is a pic of a boomslang, also in the garden.

But the scariest visitors so far have got to be the hippo's. Thankfully they can't fit through the mesh holes in the fence and they have tried to push it over yet.

Yes, big eyes is a definite indication with a Boomslang.

Now, have a look at the photo, I think the shade falling above the head makes the head seem bigger than it is. If you take this in to account, you suddenly realise that those eyes are actually huge in relation to the head. I also had a look at the shape of the head, it is very sharp, which again corresponds the the Boomslang. With a black mamba you expect a big strong and rather blunt ending head. Also look at the colour on the top jaw ... not expected in black mamba.

Most people think that Boomslang are green. But that is the males. The females are olive to brown on top and dirty white to brown at the bottom. This snake would fit in to that range. Boomslang are known for a wide colour variation.

I am not sure. The shade above the heads make the id. difficult, because it obscures the real shape, which would have been decisive in deciding whether it may indeed be a black mamba.

It is also difficult to judge the build of the snake from a photo. Is it a large strong snake ... then you are looking at a black mamba. An open mouth with a black gape ... again black mamba.

Maybe one of our snake gurus can help on this one ...

Marissa that is a juvinile Boomslang ( head colouration and shape as well as size of eye are a dead give away)- probably a female.

That is 100% a Male Boomslang Dispholidus typus no other snake is Southern Africa Has those colours. This colour is typical for Boomslang from the western Cape.

They are also interestng as they are the only snake species in Southern Africa That Are Sexually Dimorphic.

One of The most Venomous snakes drop for drop in AFRICA.
Although they are fairy unaggressive and seldom bite.

Great Sighting!
