Gymkhana FOUR

Scientists unveil 20 new species – including a giant blue scorpion and massive hairy spider


For 20 years, field scientists working with Conversation International have been exploring some of the world’s most abundant, mysterious and threatened tropical ecosystems.
To date, they have discovered more than 1,300 species new to science – although so far only 500 or so have been formally described by taxonomists, in terms of classification and naming.
And now, to celebrate their 20 years of cataloguing, the group has released 20 of their favorite finds.
While some – like the fish that flashes a beautiful array of colors when it is in love – make a great sight, others are more than likely to quiver, such as the giant blue scorpion, or the ants which hook on to each other with sharp barbs when threatened.
And arachnophobias – take a deep breath, because this is what is thought to be the largest tarantula known to exist – oh, and it eats lizards.
Brave scientists: To discover a species such as the goliath bird-eating spider is one thing – to put your hand next to it is quite another
Sends a shiver: This is the largest (by mass) spider in the world, reaching the weight of 170g and a leg span of 30cm
The giant spider is the Goliath bird eating spider (theraphosa blonde) and is the largest (by mass) spider in the world, reaching the weight of 170g and leg span of 30cm.
It was observed by Conservation International’s Rapid Assessment Program scientists in Guyana in 2006, where it lives in burrows on the floor of lowland rainforests.
Despite the name, it feeds primarily on invertebrates – but has been observed eating small mammals, lizards and even venomous snakes.
They have venom fangs, which are not deadly to humans, but their main line of defense are hairs that cover their entire body – when threatened their rub their legs against the abdomen and send a cloud of microscopic barbs that lodge in the skin and mucus membranes of the attacker, causing pain and long-lasting irritation.

The "Giant Wave" Supercell Pictures That Will Blow You Away

The results of the 2011 spring storm chasing season are in. Mike Hollingstead from Extreme Instability has been chasing storms for many years (his site is always a fascinating read for thrill-seekers). We featured his adventures before - see, for example, our article "Fog Storm Over Badlands". However this time, what you're going to see is going to blow you away - this is possibly the most epic sight on the whole Earth:

Mike suggests playing "Exogenesis Symphony Pt 1: Overture" by Muse, while looking at these pictures... "If the storm could pick a song to have playing for it, it would pick that song.":
