The origin of the ram’s horn squid (Spirula spirula Linnaeus, 1758). The article presents evidence regarding the origin of the ram’s horn squid from spiral-shelled forms. The geological age of the species is revised from the Miocene to the Jurassic. The causes of the reorientation of the shell are elucidated. The mode of life of the mollusk is specified.
