Le Rat gris, \u00e9galement appel\u00e9 Rat d’\u00e9gout ou Surmulot (Rattus norvegicus<\/em>) est un Mammif\u00e8re de la famille des Murid\u00e9s.<\/p>\n

Il fr\u00e9quente les milieux humides comme les berges des rivi\u00e8res, les bords des foss\u00e9s, les canalisations mais \u00e9galement les d\u00e9p\u00f4ts d’ordures.<\/p>\n

Surtout actifs en fin de journ\u00e9e et la nuit, les membres de l’esp\u00e8ce \u00e9voluent au sein de groupes familiaux hi\u00e9rarchis\u00e9s.<\/p>\n

  <\/p>\n

Le Rat gris est caract\u00e9ris\u00e9 par un corps allong\u00e9 et relativement trapu, termin\u00e9 par une queue \u00e9cailleuse. \u00c0 l’avant de la t\u00eate, le museau en biseau arbore des poils sensoriels, les vibrisses. La t\u00eate porte en outre des oreilles et des yeux de petites tailles.<\/p>\n

Le pelage est court, dense et raide, de couleur gris-brun sur le dos et plus clair sur le ventre. <\/p>\n

Sa longueur peut atteindre 50 cm, dont 22 cm pour la queue. Sa masse maximale est de l’ordre de 500 g.<\/p>\n

  <\/p>\n

Le Rat gris a un r\u00e9gime alimentaire tr\u00e8s diversifi\u00e9, compos\u00e9 principalement de fruits, de graines mais aussi de viande.
\nEn ville, il se nourrit souvent de d\u00e9chets alors qu’en milieu rural il profite plut\u00f4t des r\u00e9serves alimentaires.<\/p>\n

Il est qualifi\u00e9 d’omnivore.<\/p>\n

  <\/p>\n

L’esp\u00e8ce se reproduit principalement en \u00e9t\u00e9 et en automne, mais lorsque les conditions sont favorables et la nourriture abondante, la reproduction peut intervenir toute l’ann\u00e9e.<\/p>\n

Apr\u00e8s une gestation de trois semaines environ, la femelle donne g\u00e9n\u00e9ralement naissance \u00e0 sept ou huit jeunes, aveugles et nus.
\nApr\u00e8s trois semaines, ils quittent le nid.<\/p>\n

Ils acqui\u00e8rent la maturit\u00e9 sexuelle et la capacit\u00e9 \u00e0 se reproduire d\u00e8s l’\u00e2ge de trois mois.<\/p>\n
