When we think of spiders, we usually think that they use spider webs as traps to catch their prey. But not all spiders do this ... Watch the net-casting spider use their sticky spider silk to hunt their prey:
The spider then carefully crafts its distinctive net using a different type of silk.
"They spin some of the silk at its most extended so its already at full stretch when its spun so that when its off the scaffold it'll immediately shrink to its non-stretched size," he said.
"They hit the prey with it at full stretch and then they relax it so that it gets caught into it, almost like a purse net."

No numbers greater than five? Wow! How do they manage in the jungle with only half the usual supply of fingers and toes?
The desired knowledge comes from -- get this -- reading the damned article.
I just find it hard to believe there are any more truly untouched tribes in the wilds of anywhere. Supposedly the Tasaday had no word for blue. A color they never encountered despite being able to see the sky. These people supposedly went undiscovered until 1970, living in a cave a three hour hike from town.
I am not surprised that there are cultures that see things differently. That is normal. Pick up a bible. ever wonder why 40 keeps showing in days of rain and years in the wilderness? Or Methusela living 900 years?
They were the preliterate middle easterners' descriptions of a "shiteload." But to not pick up on base ten?
Pierre Pica's reluctance to discuss specific facts and figures in the article almost screams "Kippendorf's Tribe" to me.
And the Munduruku have been living peacefully within Brazil since their last makor tribal wars in about 1800.
Maybe of the article linked originated somewhere besides that paragon of journalism, The Guardian, it would have been easier to buy
Instead of our frantic measuring, pacing, dividing...
Ah what bliss---
There is no beginnig, there is no end........
For whatever reason, this reminds me of how our brain is hardwired to overestimate angle of inclination, probably so we don't try to climb steep hills.
So, it seems that the ability to count more than 5 isn't particularly important in evolution, but the ability to discourage oneself from climbing steep hills was (yes, I know that's not how evolution works, so no hate mails, mmkay?)
