Nu filu (plurali: fila) è nu taxon usatu ntâ classificazzioni scintìfica pi tutti li cosi viventi. La palora latina Phyla veni dû grecu phylai chi foru li gruppi di pirsuni chi vutàvanu ntê stati dâ Grecia antica. Li fila rapprisèntanu li cchiù granni gruppi d'armali e autri cosi viventi chi pussèdinu certi carattiristichi biològgichi. A li voti li fila vennu divisi ntra suprafila.

Li fila cchiù canusciuti sunnu Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Artropoda, Echinodermata, Chordata; l'umani s'appartennu cu st'ùrtimu.

Oi lu sistema dî tri duminî veni usatu largamenti e chissu agghiunci lu liveddu di Duminiu supra Regnu comu ddu liveddu cchiù autu.
