A quick post.

First a thanks to everyone who commented the other day, it is good to hear from you.
“You’re doing OK, keep it up” is a message I can certainly live with.

Today was pretty hot, (about 38°C or 100°F in the old money). It was also really humid. So it was not at all surprising that the weather built into thunderstorms in the evening.

About 6:00 pm the most amazing black clouds began moving across from the west.

They the sky got so dark and the clouds were so ominous looking that I thought a couple of shots were worth posting.

This is looking diagonally across the road.

And this is looking directly across the road from our front door.

Now back briefly to my throw away statement about Aussie snake venom in my last post.

According to my nearest and dearest, I was telling you porkies.

She hopped on the website belonging to The University of Melbourne’s Australian Venom Research Unit.

According to their data, which I provide below, out of the 25 most poisonous snakes in the world, 1 through to 11 on the list are Aussie species. Further, a full 20 of the 25 are from Oz as well.


The information below is lifted from their site.

World's Most Venomous Snakes

Which snake species is the most venomous depends on the measure used. The average or the maximum venom yield from milking could be suggested, but these measures can be criticised as not reflecting the impact of a real bite. The measure generally acknowledged as best reflecting how dangerous a snake's venom is is that of LD50. The lower this number, the less venom is required to cause death. By that measure, the most venomous snake in the world is Australia's inland taipan (Oxyuranus microlepidotus). The table below gives the top 25 species in order, their LD50, and their distribution.


Snake Species LD50* Distribution
1. Inland taipan 0.025 Australia
2. Eastern brown snake 0.053 Australia
3. Coastal taipan 0.099 Australia
4. Tiger snake 0.118 Australia
5. Black tiger snake 0.131 Australia
6. Beaked sea snake 0.164 Australia
7. Black tiger snake (Chappell Island ssp.) 0.194 - 0.338 Australia
8. Death adder 0.400 Australia
9. Gwardar 0.473 Australia
10. Spotted brown snake 0.360 (in bovine serum albumin) Australia
11. Australian copperhead 0.560 Australia
12. Cobra 0.565 Asia
13. Dugite 0.660 Australia
14. Papuan black snake 1.09 New Guinea
15. Stephens' banded snake 1.36 Australia
16. Rough scaled snake 1.36 Australia
17. King cobra 1.80 Asia
18. Blue-bellied black snake 2.13 Australia
19. Collett's snake 2.38 Australia
20. Mulga snake 2.38 Australia
21. Red-bellied black snake 2.52 Australia

So I suppose the moral of the story is: tread carefully in the Great South Land.
