  Catfishes order siluriformes includes many commercially and economically important species throughout the world. Here, we in- vestigated genetic relationships and diversity in this order. Sequence comparisons and phylogenetic analyses revealed considerable variations between mitochondrial CO1 genes among twenty four siluriformes species. The frequencies of nucleotide are 23.80% A, 29.62% T/U, 26.63% C and 19.95% G. Used for calculating ML values, a user-specified topology was used. The highest Log chance for this calculation was -9413.645. Evolutionary diversity over all sequencing average estimated numbers of base substitutions per loca- tion sequence pairs were 4.984. Our results suggest that Batasio travancoria formed a single clade; R. rita, W. attu, M. montanus and B. bagarius comprised a single separate family; and M. vittatus, M. horai, B. tengana, M. malabaricus, M. bacourti, M. singaringan, M. bleekeri, M. gulio, M. multiradiatus, M. rhegma, M. cavasius, M. tengara, S. aor, S. seenghala, B. bajad, B. filamentosus, B. macracanthus, P. siamensis, E. vacha and B. travancoria formed single subfamily.
