Characterization of the complete mitochondrial genome of Cavisoma magnum () (Acanthocephala: Palaeacanthocephala), first representative of the family Cavisomidae, and its phylogenetic implications.

The phylum Acanthocephala is a small group of endoparasites occurring in the alimentary canal of all major lineages of vertebrates worldwide. In the present study, the complete mitochondrial (mt) genome of Cavisoma magnum (Southwell, 1927) (Palaeacanthocephala: Echinorhynchida) was determined and annotated, the representative of the family Cavisomidae with the characterization of the complete mt genome firstly decoded. The mt genome of this acanthocephalan is 13,594 bp in length, containing 36 genes plus two non-coding regions.

Cavisoma magnum (Cavisomidae), a unique Pacific acanthocephalan redescribed from an unusual host, Mugil cephalus (Mugilidae), in the Arabian Gulf, with notes on histopathology and metal analysis.

Cavisoma magnum (Southwell, 1927) Van Cleave, 1931 was originally described from a sea bass, Serranus sp. and spotted surgeonfish, Ctenochaetus strigosus (Perciformes) off Sri Lanka before its more recent redescription from milkfish in the Philippines in 1995. These reports were based on only light infections of their host fishes.
