Champsodon is the sole genus in the family Champsodontidae. ^[2] These fishes, the crocodile toothfishes, are native to the Indo-Pacific region.

Although Champsodon is the only extant genus of this family, a close relative is known in the extinct † Eochampsodon Bannikov, 2004 from the Middle Eocene (Bartonian) of the North Caucasus, Russia. ^[3]

Species

The currently recognized species in this genus are: ^[4]

• Champsodon atridorsalis Ochiai & I. Nakamura, 1964
• Champsodon capensis Regan, 1908 (gaper)
• Champsodon fimbriatus C. H. Gilbert, 1905
• Champsodon guentheri Regan, 1908 (Günther's sabre-gills)
• Champsodon longipinnis Matsubara & Amaoka, 1964
• Champsodon machaeratus Nemeth, 1994
• Champsodon nudivittis (J. D. Ogilby, 1895)
• Champsodon omanensis Regan, 1908
• Champsodon pantolepis Nemeth, 1994
• Champsodon sagittus Nemeth, 1994
• Champsodon sechellensis Regan, 1908
• Champsodon snyderi V. Franz, 1910
• Champsodon vorax Günther, 1867

In addition to the extinct † Eochampsodon , the following fossil Champsodon species are known:

• † Champsodon tethensis Bannikov, 2018 - Middle Eocene (Bartonian) of North Caucasus, Russia ^[5]
• † Champsodon timaruensis Schwarzhans, 2019 - Early Miocene of New Zealand [ otolith] ^[6]
