Africa-Press – Djibouti. <\/strong><\/span> <\/b>Dans The Amazing Spider-Man 2 (2014), Max Dillon rec\u0327oit de multiples de\u0301charges en tombant dans un bassin rempli de poissons e\u0301lectriques, devenant ainsi Electro. Si la gene\u0300se du super-gredin joue\u0301 par Jamie Foxx est bien e\u0301videmment de la pure fantasmagorie, tout n\u2019est pas a\u0300 jeter dans cette extrapolation du pouvoir e\u0301lectrique de certains animaux.<\/p>\n

Ne les appelez pas anguilles : ce sont des gymnotes !<\/b><\/p>\n

Tout d\u2019abord, dissipons un malentendu commun entretenu dans le film The Amazing Spider-man 2 : le destin d\u2019un he\u0301ros (notre critique du film est a\u0300 lire ici). En de\u0301pit de leur aspect serpentiforme, les poissons e\u0301lectriques ne sont pas des anguilles mais des gymnotes. Ces poissons d\u2019eau douce d\u2019Ame\u0301rique du Sud et d\u2019Ame\u0301rique centrale appartiennent a\u0300 la famille des gymnotidae. Tous ont des organes e\u0301lectriques nomme\u0301s e\u0301lectrolytes gra\u0302ce auxquels ils peuvent localiser des proies ou des obstacles, sans doute communiquer, mais e\u0301galement estourbir efficacement un ennemi.<\/p>\n

MONSTRE.<\/b> Le plus impressionnant d\u2019entre eux, le bien nomme\u0301 Electrophorus electricus, est un monstre de deux me\u0300tres et demi de long, capable de ge\u0301ne\u0301rer des chocs e\u0301lectriques d\u2019envergure. Plus l\u2019animal est grand, plus le nombre d\u2019e\u0301lectrolytes empile\u0301s dans ses organes est important.<\/p>\n

Ainsi, si la tension de\u0301livre\u0301e par un seul e\u0301lectrolyte est ridiculement petite, de l\u2019ordre de 150 millivolts (mV), tout change de\u0300s que plusieurs milliers d\u2019entre eux sont arrange\u0301s en se\u0301rie. Comme l\u2019organisme d\u2019un gymnote contient en moyenne pre\u0300s de 4000 e\u0301lectrolytes, la tension e\u0301lectrique atteinte par l\u2019animal est de l’ordre des 600 Volts !…<\/p>\n

Attention, cette haute valeur n’est pas force\u0301ment synonyme d’e\u0301lectrocution : le courant e\u0301lectrique est aussi de\u0301fini par son intensite\u0301 (en Ampe\u0300re) ; a\u0300 de faibles valeurs, il peut e\u0302tre inoffensif. Reste que l’aspect \u00ab\u00a0haute tension\u00a0\u00bb de l’Electrophorus electricus lui vaut une re\u0301putation sulfureuse dans sa re\u0301gion natale.<\/p>\n

Une anguille qui pulve\u0301rise une machette<\/b><\/p>\n

En Amazonie ou\u0300 ils pullulent, on e\u0301vite donc sagement de croiser leur route, surtout que la chair n\u2019est pas tre\u0300s savoureuse et que le gymnote ne constitue pas un met recherche\u0301… \u00ab\u00a0Ce sont des animaux qui, rendus confiants par la puissance de leur arme e\u0301lectrique, n\u2019ont absolument pas peur des humains. Quand vous en voyez un approcher du rivage, il vaut mieux prendre ses jambes a\u0300 son cou\u00a0\u00bb, te\u0301moigne Morilo Dias.<\/p>\n

\u00ab\u00a0HISTOIRE\u00a0\u00bb.<\/b> Actuellement doctorant dans le de\u0301partement des milieux et peuplements aquatiques du Muse\u0301um National d\u2019Histoire Naturelle de Paris, le chercheur, originaire du Bre\u0301sil, a appris tre\u0300s jeune a\u0300 se me\u0301fier de l\u2019animal. \u00ab\u00a0Quantite\u0301 d\u2019histoires circulent. Notamment celle d\u2019un pe\u0302cheur qui avait tente\u0301 d\u2019en tuer un d\u2019un coup de machette. Le poisson a e\u0301te\u0301 coupe\u0301 en deux mais sa machette s\u2019est vue pulve\u0301riser et les morceaux e\u0301parpille\u0301s a\u0300 plusieurs me\u0300tres de distance sous le coup de la de\u0301charge e\u0301lectrique e\u0301mise par le gymnote !\u00a0\u00bb<\/p>\n

Conclusion : aucun humain n\u2019he\u0301ritera jamais des pouvoirs du gymnote en se retrouvant a\u0300 proximite\u0301 de l\u2019animal. Mais la\u0300 ou\u0300 la fiction ne ment pas, c\u2019est que se retrouver dans un bassin rempli de ces monstres e\u0301lectriques peut s’ave\u0301rer fort de\u0301sagre\u0301able…<\/p>\n
