An order of green algae that includes the family Cladophoraceae and related branching filamentous forms.
From Cladophora + -ales (Latin suffix for taxonomic orders). The -ales ending is standardized in biological nomenclature to denote the order rank above family.
The deeper you go in biological classification, the names get weirder—kingdom, phylum, class, order, family, genus, species—each level has its own Latin suffix that tells experts exactly how related organisms are.
