Le Rat musqu\u00e9 (Ondatra zibethicus<\/em>) est un Mammif\u00e8re originaire d’Am\u00e9rique du nord, appartenant \u00e0 la famille des Murid\u00e9s.<\/p>\n

Il fr\u00e9quente le milieu aquatique, \u00e9voluant sur les berges des rivi\u00e8res et des \u00e9tangs dont les eaux sont calmes.
\nIl y creuse des galeries, et construit parfois des huttes sur les bords des grandes \u00e9tendues d’eau.<\/p>\n

Plut\u00f4t actifs en d\u00e9but et en fin de journ\u00e9e, les membres de l’esp\u00e8ce vivent au sein de structures familiales, compos\u00e9es des parents et des jeunes de l’ann\u00e9e. <\/p>\n

  <\/p>\n

Le Rat musqu\u00e9 est identifi\u00e9 \u00e0 sa t\u00eate volumineuse arborant un museau tronqu\u00e9.
\nIl poss\u00e8de de fortes pattes post\u00e9rieures, les pattes ant\u00e9rieures \u00e9tant plus courtes.
\nSon corps, massif, est termin\u00e9 par une queue \u00e9cailleuse tr\u00e8s sombre, aplatie lat\u00e9ralement.<\/p>\n

Il est recouvert d’un pelage dense et dru, de couleur brun sombre sur le dos, tirant parfois sur le noir. Ventralement, il est plus clair, de couleur brun-gris.<\/p>\n

La longueur du Rat musqu\u00e9 peut atteindre 60 cm, dont 25 cm pour la queue. Sa masse est de l’ordre de 1500 g.<\/p>\n

  <\/p>\n

Le Rat musqu\u00e9 se nourrit de v\u00e9g\u00e9taux comme les iris et les phragmites qu’il sectionne et emporte dans sa galerie.
\nIl consomme \u00e9galement des fruits, des graines et des l\u00e9gumes, lorsque jardins et cultures sont proches de son habitat.<\/p>\n

Bien que principalement herbivore, l’esp\u00e8ce compl\u00e8te son r\u00e9gime par des animaux aquatiques comme les Moules d’eau douce et les poissons.<\/p>\n

  <\/p>\n

La reproduction intervient au printemps et en \u00e9t\u00e9.<\/p>\n

Apr\u00e8s une gestation d’environ un mois, la femelle donne g\u00e9n\u00e9ralement naissance \u00e0 six ou sept jeunes.
\nLeur \u00e9mancipation intervient apr\u00e8s trois \u00e0 quatre semaines et leur maturit\u00e9 sexuelle apr\u00e8s un an.<\/p>\n

La rapidit\u00e9 du d\u00e9veloppement des jeunes permet \u00e0 chaque couple de produire deux \u00e0 trois port\u00e9es annuelles.<\/p>\n
