binomial_authority = Mochizuki & Ohe, 1990 The viper dogfish, "Trigonognathus kabeyai", is a dogfish, the only species in the genus "Trigonognathus", found off Wakayama and Tokushima, Japan, in the northwest Pacific Ocean at depths of between 330 and 360 m. Its maximum length is 47 cm.

The viper dogfish is a rare deepsea shark with a limited distribution area in Japan and a single record from Hawaii. Specimens have been collected from the surface to a depth of 150 m, at night where the sea was more than 1,500 m deep, by purse seine. Very little information is available on biology. Taken as bycatch of bottom trawl and purse seine fisheries, but not utilised.

Viper dogfish are ovoviviparous.
