Idioteuthis is a genus of large (>1 meter) whiplash squid. Like other mastigoteuthids, they have long tentacles with hundreds of tiny suckers on each club. In fact, the tentacle length is longer than the mantle length. The body of Idioteuthis is covered in many tiny, pointed bumps (called tubercles). Idioteuthis is found along the Western Pacific (from New Zealand to Japan).
