QUE SIGNIFIE TARDIGRADE EN ANGLAIS
Tardigrade
Les Tardigrades sont des micro-animaux segmentés en eau, avec huit jambes. Ils ont été décrits pour la première fois par le pasteur allemand Johann August Ephraim Goeze en 1773. Le nom de Tardigrada a été donné trois ans plus tard par la biologiste italienne Lazzaro Spallanzani. Depuis 1778, plus de 1 150 espèces tardigrade ont été identifiées. Les tardigrades sont classés comme des extrémophiles, des organismes qui peuvent prospérer dans un état physique ou géochimiquement extrême qui nuirait à la plupart des vies terrestres. Par exemple, les tardigrades peuvent résister à des températures allant juste au-dessus du zéro absolu, bien au-dessus du point d'ébullition de l'eau, des pressions environ six fois supérieures à celles trouvées dans les tranchées océaniques les plus profondes, des rayonnements ionisants à des doses supérieures à celles de la dose létale pour un humain , Et le vide de l'espace extra-atmosphérique. Ils peuvent aller sans nourriture ou en eau pendant plus de 10 ans, se dessécher au point où ils sont de 3% ou moins d'eau, uniquement pour se réhydrater, se fourrage et se reproduire. Habituellement, les tardigrades ont une longueur d'environ 0,5 mm lorsqu'elles sont entièrement cultivées. Ils sont courts et gros avec quatre paires de jambes, chacune avec quatre à huit griffes également appelées «disques».
