0:00:04 > 0:00:08On Deadly 60, I've had loads of incredible animal encounters.
0:00:08 > 0:00:11Here's just one of my many favourites.
0:00:12 > 0:00:16This is Deadly 60...Bites!
0:00:16 > 0:00:19I don't want you to think this series is only about
0:00:19 > 0:00:21animals that are dangerous to people.
0:00:21 > 0:00:24You've as much chance of being hurt by a wild animal
0:00:24 > 0:00:27as you have of being struck by lightning.
0:00:27 > 0:00:28Whilst wearing a gorilla suit.
0:00:28 > 0:00:32What it IS about, is animals who are dangerous in THEIR world.
0:00:32 > 0:00:34After all, if you're an insect...
0:00:35 > 0:00:39..a chameleon is the most dangerous animal in the world.
0:00:40 > 0:00:42Yuck!
0:00:47 > 0:00:51With that in mind, we're heading into the South African Bush
0:00:51 > 0:00:54to see if we can find some contenders for my Deadly 60 list.
0:00:56 > 0:00:58Ooh!
0:00:58 > 0:00:59Got something.
0:00:59 > 0:01:03This is gonna be the only... Ow!
0:01:05 > 0:01:06This...
0:01:06 > 0:01:08..is a flat rock scorpion.
0:01:08 > 0:01:12And...it's got quite a pinch on it!
0:01:12 > 0:01:17But it's actually really the pussycat of the scorpion world,
0:01:17 > 0:01:19as far as the sting goes.
0:01:19 > 0:01:22The rule of thumb is to look at a scorpion
0:01:22 > 0:01:24and look at the size of its pincers.
0:01:24 > 0:01:26If those are big, like this one here -
0:01:26 > 0:01:28he's trying to get hold of me with those -
0:01:28 > 0:01:31those are gonna be its primary weapon.
0:01:31 > 0:01:35The great thing about this flat rock scorpion is that even though
0:01:35 > 0:01:37his sting really isn't very potent,
0:01:37 > 0:01:40because he has these massive, powerful pincers,
0:01:40 > 0:01:44he'll flatten himself inside a crevice and if other scorpions
0:01:44 > 0:01:47which might have much more potent venom come nearby,
0:01:47 > 0:01:49he can literally tear them apart.
0:01:49 > 0:01:52So, although he's not very harmful to us,
0:01:52 > 0:01:54he is quite potentially harmful to other scorpions
0:01:54 > 0:01:58and that's gotta make him a candidate for the Deadly 60.
0:02:01 > 0:02:06'With so much more to see, we decide to keep going on into the night.'
0:02:13 > 0:02:18You may have noticed that I have two different colours of torches -
0:02:18 > 0:02:23the white bulb on my head and this purple light.
0:02:23 > 0:02:29Hopefully you'll see quite soon why I've got this.
0:02:31 > 0:02:33He's coming right towards me!
0:02:33 > 0:02:36With a little luck, I might not even have to wrangle him!
0:02:36 > 0:02:41It's exactly the species we're hoping to find, as well.
0:02:45 > 0:02:46Ooh!
0:02:48 > 0:02:49OK...
0:02:49 > 0:02:51Gotta hold my nerve here...
0:02:51 > 0:02:57cos I'm getting pinched but the pinch is not the problem.
0:02:57 > 0:03:00I can hold him down.
0:03:00 > 0:03:05This is the scorpion I was really hoping to find round here.
0:03:05 > 0:03:09Now I'll show you why I've been carrying this torch around.
0:03:09 > 0:03:12I get rid of my normal light...
0:03:12 > 0:03:14Look at that.
0:03:17 > 0:03:20This is one of the most curious things about scorpions -
0:03:20 > 0:03:25their exoskeleton, - their skeleton on the outside of their body -
0:03:25 > 0:03:29has this amazing glow when it's put under ultraviolet light.
0:03:29 > 0:03:33The reason for this, probably, is that because all invertebrates
0:03:33 > 0:03:36see really well in this kind of light,
0:03:36 > 0:03:40that a scorpion that's hiding in a crevice can see another one
0:03:40 > 0:03:43by seeing that ghostly green glow.
0:03:43 > 0:03:47Now, you'll notice that I haven't got this one on my hand,
0:03:47 > 0:03:48like I did the other one,
0:03:48 > 0:03:52and nor am I trying to get it to sting me, for the very simple reason
0:03:52 > 0:03:56that if it did, erm...my trip would certainly be over.
0:03:56 > 0:04:00This is probably one of the most venomous scorpions in Africa,
0:04:00 > 0:04:04and if you look at the size of the pincers and the size of the tail,
0:04:04 > 0:04:08you'll see it's exactly reversed from the scorpion I had earlier.
0:04:08 > 0:04:11The tail's big and fat, the pincers, small and thin.
0:04:11 > 0:04:15This one here has a really nasty punch.
0:04:15 > 0:04:20One of the most extraordinary things about this particular species
0:04:20 > 0:04:22is that it doesn't stop there.
0:04:22 > 0:04:25It can actually flick its venom at an attacker,
0:04:25 > 0:04:28and it can be really, really accurate,
0:04:28 > 0:04:33I've gotta say, this extraordinary creature is going into my Deadly 60.
0:04:35 > 0:04:39This scorpion is one of the very few in the world that could kill me,
0:04:39 > 0:04:42and if it didn't, it would almost certainly put me out of action
0:04:42 > 0:04:44for a long time.
0:04:44 > 0:04:46More importantly, its large tail and sting,
0:04:46 > 0:04:48laden with powerful neurotoxic venom,
0:04:48 > 0:04:52combine to make this scorpion extremely deadly in its own world.
