Ghost in the Shell, known in Japan as Mobile Armored Riot Police (Japanese: 攻殻機動隊 , Hepburn: Kōkaku Kidōtai ) , is a "seinen" manga series written and illustrated by Masamune Shirow, which spawned the media franchise of the same name.  The manga, first serialized in 1989 under the subtitle of "The Ghost in the Shell", and later published as its own "tankōbon" volumes by Kodansha, told the story of the fictional counter-cyberterrorist organization Public Security Section 9, led by protagonist Major Motoko Kusanagi, in the mid 21st century of Japan.

Latouchella is an extinct genus of marine invertebrate animal, that is considered to be a mollusk and which may be a sea snail, a gastropod.  It is a helcionellid from the Tommotian epoch of what is now Siberia.  Its tightly-coiled, spiral shell contains a number of low "walls" running up the front surface of the interior; these would have directed water currents within its shell.  Between these walls are a series of furrows, parallel to the shell's aperture, giving casts of the internal structure the appearance of a railway line, with sleepers (created by furrows) tying together paired rails that run towards the apex of the shell. Plectronoceras is the earliest known shelly cephalopod, dating to the Late Cambrian.  None of the fossils are complete, and none show the tip or opening of the shell.  Approximately half of its shell was filled with septa; 7 were recorded in a 2 cm shell.  Its shell contains transverse septa separated by about half a millimetre, with a siphuncle on its concave side.  Its morphology matches closely to that hypothesised for the last common ancestor of all cephalopods.
