D’une longueur de 20\u00a0mm, le corps a une forme effil\u00e9e et est recouvert d’\u00e9cailles brillantes.<\/p>\n
\u00c0 l’avant, la t\u00eate est munie de deux petits yeux compos\u00e9s situ\u00e9s en position lat\u00e9rale et ne se touchant pas, et de deux antennes longues et fines.
\nLes pi\u00e8ces buccales sont de type broyeur.<\/p>\n
En arri\u00e8re de la t\u00eate, le thorax porte ventralement trois paires de pattes mais est d\u00e9pourvu d’aile.<\/p>\n
L’abdomen, post\u00e9rieur, est quant \u00e0 lui muni de petits appendices, et est termin\u00e9 par trois prolongements (deux cerques lat\u00e9raux et une expansion m\u00e9diane appel\u00e9e \u00e9piprocte).
\nTous sont bord\u00e9s de soies.<\/p>\n

Cycle de vie<\/h2>\n
La dur\u00e9e de vie du Poisson d’argent est de l’ordre de 4 \u00e0 5 ans.<\/p>\n
Apr\u00e8s l’accouplement, la femelle pond des \u0153ufs au sein desquels se d\u00e9roule le d\u00e9veloppement embryonnaire.
\nLeur \u00e9closion lib\u00e8re des individus juv\u00e9niles, semblables aux adultes en termes de morphologie, d’anatomie mais aussi de mode et de milieu de vie.<\/p>\n
Les individus juv\u00e9niles connaissent alors un d\u00e9veloppement post-embryonnaire caract\u00e9ris\u00e9 par une augmentation de taille et de masse. Cette croissance est r\u00e9alis\u00e9e \u00e0 la faveur de mues, processus au cours desquels la cuticule rigide qui recouvre le corps est renouvel\u00e9e, remplac\u00e9e par une nouvelle cuticule temporairement souple, qui autorise l’accroissement des dimensions.
\nCe n’est qu’apr\u00e8s les premi\u00e8res mues que les \u00e9cailles apparaissent.<\/p>\n
Ainsi, six stades au moins sont d\u00e9nombr\u00e9s entre l’\u00e9closion et l’acquisition de la maturit\u00e9 sexuelle, qui d\u00e9termine la fin du d\u00e9veloppement post-embryonnaire.<\/p>\n
L’individu est alors devenu un imago, capable de reproduction. Les mues se poursuivent pendant la phase imaginale du cycle de vie.<\/p>\n
Du fait des caract\u00e9ristiques de leur cycle de vie et en particulier de l’absence de larve et de m\u00e9tamorphose, les Thysanoures sont qualifi\u00e9s d’am\u00e9taboles.<\/p>\n

\u00c9tymologiquement, le terme Thysanoure d\u00e9rive de \u00ab\u00a0thysanos\u00a0\u00bb signifiant \u00ab\u00a0frange\u00a0\u00bb et \u00ab\u00a0oura\u00a0\u00bb\u00a0signifiant \u00ab\u00a0queue\u00a0\u00bb. Il est une r\u00e9f\u00e9rence aux soies port\u00e9es par les cerques et l’\u00e9piprocte. Le taxon des Thysanoures est peu nombreux, comportant environ 400 esp\u00e8ces.
