The tentacles are of a greater length in comparison to their arms, also being retractile.Īll of their ten arms (including the two tentacles) have disc-shaped suckers, with some of the suckers bearing hooks on them for a better grip. In the ventral part of their body lie eight arms and two long tentacles surrounding their mouth. Each side of the head has two large eyes giving them a 360°vision.
