Abstract: Animal parasitic nematodes are one of the most diverse and abundant groups of animal parasites and pose severe threats to humans, domestic and wild animals.The mitogenome is the only extranuclear genetic material of animal parasitic nematodes and is an important information carrier for studying nematode species identification, genetic evolution and phylogenetics, as well as the prevention and control of nematodosis.In recent years, with the rapid development of next-generation sequencing and bioinformatics technology, more and more mitogenomes of animal parasitic nematodes were decoded, and up to February 28, 2022, there are 283 mitogenomes of animal parasitic nematodes deposited in GenBank of NCBI, including 213 nematode species, belonging to two subclasses of Secernentea and Adenophorea.Despite this, there is still a lack of systematic and comprehensive generalization about the characteristics and applications of animal parasitic nematode mitogenomes.Thus, this review aimed to summarize the structure and content, base preference, variations in tRNA/AT-enriched regions of the existing animal parasitic nematode mitogenomes which are sequenced so far and propose new gene arrangement (GA) divisions which contain 39 Gas, and also further concluded the mitogenome applications in population genetics, phylogeny, molecular epidemiology and diagnostics of animal parasitic nematodes, aiming to provide an informative reference for the prevention and control of animal nematodosis.

Key words: animal parasitic nematodes; mitogenomes; genetic evolution
