\u2728L’anatomie d’un mollusque hors du commun<\/strong>\u2728
La pieuvre, que l’on appelle aussi fr\u00e9quemment le poulpe, est un mollusque c\u00e9phalopode qui peuple nos oc\u00e9ans depuis pr\u00e8s de 300 millions d’ann\u00e9es. Contrairement aux autres mollusques comme l’escargot ou la moule, elle ne poss\u00e8de aucune coquille, ni interne ni externe. Son corps est enti\u00e8rement compos\u00e9 de muscles et de tissus souples, ce qui lui conf\u00e8re une agilit\u00e9 extraordinaire : elle est capable de compresser la totalit\u00e9 de son organisme pour se faufiler dans des interstices pas plus larges qu’une pi\u00e8ce de monnaie. Son seul point rigide est un bec puissant, situ\u00e9 au centre de ses bras, qu’elle utilise pour briser les carapaces de ses proies.<\/p>\n\n\n\n

\u2728Un syst\u00e8me vital complexe et fascinant<\/strong>\u2728
Sur le plan physiologique, la pieuvre semble presque extraterrestre. Elle poss\u00e8de trois c\u0153urs qui travaillent de concert : deux sont charg\u00e9s de propulser le sang vers les branchies pour l’oxyg\u00e9ner, tandis que le troisi\u00e8me fait circuler ce sang dans tout le reste du corps. Une autre particularit\u00e9 frappante est la couleur de son sang, qui est bleu et non rouge. Cette couleur est due \u00e0 la pr\u00e9sence d’h\u00e9mocyanine, une prot\u00e9ine riche en cuivre, bien plus efficace que notre fer (h\u00e9moglobine) pour transporter l’oxyg\u00e8ne dans les eaux froides et pauvres en oxyg\u00e8ne des profondeurs marines.<\/p>\n\n\n\n
