The parapodia of Notarchus indicus are almost completely fused. There is a small anterior opening to allow an exchange of water to the mantle cavity, which enables it to escape from danger by swimming by jet propulsion, Bill Rudman decribes how it swims at the Sea-Slug Forum. Its background colour varies from translucent yellowish-tan to greenish brown. It is covered with small white and/or yellow spots, and some larger darker spots, which are in some specimens black. It has larger conical tubercles.Notarchus indicus has no shell.
More information on Notarchus indicus are on Bill Rudman's Sea-Slug Forum!
