Idiosepius is a genus of squids in the family Idiosepiidae. Most well known for their incredibly tiny size, these squids range from 10 to 18 mm (0.39 to 0.75 in) in adult specimens. Members of this genus are of no interest to commercial fisheries. Idiosepius are found primarily in tropical and temperate waters throughout the Indo-Pacific, often found in association with seagrass and mangrove roots.
== Anatomy == Idiosepius have 8 tentacles and 2 arms and have an adhesive organ located on the dorsal mantle side at the posterior end between the fins. Pygmy squid brain structures and nervous system are comparable to other squids and octopuses but they have a more developed optical tract. The beaks of Idiosepius show small toothlike structures, a genus specific feature which can be useful in distinguishing Idiosepius species.
