Description
Color: The species is of dull greyish or ash colour and has smooth mantle surface. The posterodorsal and posterventral surfaces of the body have greenish iridescence.

The body is large and somewhat loose in consistency. The mantle skin is smooth. The head is small and united with the mantle by a narrow nuchal region. The eyes are very small. The arms are very long and tapering to attenuate tips, the dorsal ones are always the longest; arm formula usually 1.2.3.4. The web between the arms is well developed; the suckers are fleshy and without any chitinous rings and are arranged in alternating double rows on all the arms. The basal suckers are large and the distal ones very minute. There are eight water pores, each located in between the interbrachial membrane near the base of the arms, each pore leading to a small oval shaped pouch embedded in the oral side of the muscular web. The pouches can be easily seen by gently teasing out the superficial layer of skin in fresh animals. In males, the third arm on the right side is hectocotylized and the ligula is small, smooth, poorly developed and not easily discernible; it forms only about 3 per cent of the arm.
