Description
Size: Length of the buttons 0.050 mm - 0.063 mm, breadth 0.025 mm - 0.033 mm; height of the table is 0.042 mm; diameter of the disc 0.037 mm- 0.054 mm.

Color: Reddish-brown but looks black on contraction.

Large and snake-like forms with leathery skin . The pedicels are large with well developed sucking discs; tentacles are 20 in number and are ventrally placed. There is a well developed tentacular collar with a fimbriated margin. In the calcareous ring each radial is large and has a deep groove while the inter-radial is a short, stump-like projection, there is a single polian vesicle and a single stone canal. The respiratory trees are well developed, Cuvierian tubules are also well developed.

The spicules consist of an external layer of tables with complete or incomplete discs often reduced to four holes, one at the base of each pillar. Spire is low and often partly reduced, but when complete, it ends in a flattened crown of eight or twelve teeth. Inner layer consists of regular six holed buttons. The buttons may sometimes be asymmetrical. Pedicels are with large end plates and a few broad perforated plates with more or less slit like holes; buttons are dumb-bell shaped with a pair of holes at either end.

On being disturbed the animal throws out the cuvierian tubules which are abundant. The species has the peculiar habit of tucking its posterior end under a stone, the anterior end which projects out from the stone keeps
on moving with the ventrally directed tentacles.
