Secrets of the American jungle - The Civilisation of Spiders

The aim of Professor Bertrand Krafft’s mission in French Guyana is to study the huge colonies of ‘Anelosimus’. These are the spiders that have the fascinating tendency to live collectively in society. Their nests are among the biggest in the world, ranging in widths of up to 20 metres and lengths of up to 50 metres.
Contrary to most spiders, which are irascible and solitary, the Anelosimus live, eat, weave, hunt and reproduce collectively without animosity.
Indeed, hundreds of these spiders are capable of synchronising their individual abrupt movements into one spectacular collective endeavour when hunting a prey in their enormous web.
In parallel, to tell us more of the famous Guyanese trapdoor spider and especially to bring us up close to the biggest of all trapdoor spiders, the ‘Theraphosa’, Bertrand Krafft meets up with Franck Phan, an avid arachnophile, for a nighttime excursion in the forest…
Frogs balancing on the ends of branches, spiders socialising in their thousands, ants that like to do gardening and giant trapdoor spiders: in the “SECRETS OF THE AMERICAN JUNGLE” series (3 x 52’, ants, frogs and spiders) we visit the astonishing world of these little creatures of the equatorial forest on the north-eastern coast of the South American continent in Guyana. This forest, which has been well protected until recently, is one of the richest in the world in terms of animal diversity. Professor Bertrand Krafft guides us to the enormous nests created by a species of sociable spiders that also hunt collectively in a perfectly synchronised movement. The film also takes us on a night time excursion to observe the Leblondi trapdoor spiders, the biggest of their kind in the world. We also discover the amblipyge, one of the most frightening creatures in Guyana.
The second part is about the Kunawalu tree frog and the metronome tree frog. They live and reproduce in the branches of trees and feed their tadpoles by laying a second generation of eggs. In order to approach them at heights of 30 metres, Philippe Gaucher needed to rig about fifty trees with ropes. The film also shows the “explosive ovulation” during which thousands of frogs copulate simultaneously.
Professor Alain Dejean’s research team specialises in ants that live only in trees. Not only are these types of ants the tree’s loyal friend, protecting it against the many parasites that devour its leaves, but they also cultivate gardens of little plants in the tree branches where they live.

Les araignées sont des créatures fascinantes et ce sont des êtres vivants qui méritent tout notre respect !

A 8 minute, le nattateur dit "ce ne sont que quelques piqûres", sauf que ce ne sont pas des piqûres mais des morsures. Ça la fou bien pour un documentaire sur les araignées....
