Order: Cottiformes, Family: Cyclopteridae, Genus: Eumicrotremus
Name-Dango is in the Cyclopteridae family, the same family as the Fuusen-Uo and has the same features, the adhesive discs and the protective coloration, as the Fuusen-Uo.
The main difference is the wart-like tubercles on the body and its growth rate. While the Fuusen-Uo becomes an adult in one year, the Name-Dango takes twice as long to become adult.
Its habitat is south of the Sea of Okhotsk and off the coast of the Kuril Islands.
