The Northern Pygmy Squid ("Idiosepius paradoxus") is a species of bobtail squid native to the western Pacific Ocean, including the waters off South Korea, northern Australia, as well as the Japanese islands of Honshū, Kyūshū, and southern Hokkaidō. It inhabits shallow, inshore waters.Reid, A. 2005. Family Idiosepiidae. "In:" P. Jereb & C.F.E. Roper, eds. "Cephalopods of the world. An annotated and illustrated catalogue of species known to date.

Rome, FAO. pp. 208–210.]

"I. paradoxus" grows to 16 mm in mantle length.

The type specimen was collected off Kadsiyama in Tokyo Bay. It is deposited at the Musee Zoologique in Strasbourg. [http://www.mnh.si.edu/cephs/newclass.pdf Current Classification of Recent Cephalopoda] ]
