Le double cauchemar : le serpent araignée

12.10.2015 | par Loïc Mangin | Articles & Billets

Vous avez horreur des serpents, et la moindre allusion à ces créatures vous donne des frissons ? Vous criez à la vue d’une araignée et vous enfuyez en gesticulant comme un damné ? Voici votre double cauchemar : Pseudocerastes urarachnoides.

Son nom anglais est spider-tailed horned viper, c’est-à-dire vipère cornue à queue en araignée. Ce reptile, endémique de l’Iran occidental, dans les monts Zagros, a été découvert une première fois en 1960, puis redécouvert en 2006 par Hamid Bostanchi

Pourquoi un tel nom ? Et bien voilà la réponse en photo.

De fait, l’extrémité de sa queue est hérissée de petites excroissances, l’ensemble ressemblant à une sorte d’araignée. À vous de juger.

À quoi lui sert un tel appendice ? À attirer ses proies, le plus souvent des oiseaux à la recherche de nourriture, et notamment des insectes et autres arthropodes.

Et le stratagème fonctionne plutôt bien, regardez.

Petit jeu du jour : imaginez d’autres doubles cauchemars !

    "Grizzly Venom" incident, a few years ago, when Doctor Manhattan and his fellow Avengers were still living in South Korea, we learned about one of Marvel's most iconic villains. After being defeated by Red Skull (with help from Captain America) with no discernible means to overcome him, he was released into Hell where he lived out the rest IRL life as an undead dragon called Kraven the Hunter, but eventually grew up on Earth after some nefarious plot put it all behind them and left both man and woman trapped deep in hell at sea.
