A hores d’ara s’han catalogat m\u00e9s d’1,4 milions d’esp\u00e8cies en tot el m\u00f3n, per\u00f2 es pensa que el nombre\u00a0 d’esp\u00e8cies que possiblement hi ha al planeta supera amb escreix aquesta xifra. Les dades que teniu a continuaci\u00f3 ens mostren la quantitat d’esp\u00e8cies conegudes de cada grup d’organismes. Mentre que els animals de p\u00e8l i ploma s\u00f3n ben coneguts, els invertebrats s\u00f3n molt desconeguts, perqu\u00e8 no es veuen amb facilitat i s\u00f3n poc atractius. Mentre que a Europa, en alguns pa\u00efsos es coneix el 100% dels seus animals, a altres parts dels m\u00f3n ni tan sols estem segurs de con\u00e8ixer tots els vertebrats per\u00f2 r\u00e8ptils i peixos s\u00f3n potser els m\u00e9s desconeguts. Hi ha \u00e0rees senceres de la Terra on es desconeixen grups sencers d\u2019insectes, per exemple de d\u00edpters.<\/p>\n
Mam\u00edfers: n’hi ha 13.500<\/p>\n
Ocells: n’hi ha 9.500<\/p>\n
Peixos: aproximadament 24.000<\/p>\n
Invertebrats: aproximadament 1 mili\u00f3<\/p>\n
