Sepia pulchra grows to a mantle length of 22 mm.[4] It has a warty mantle and is reddish-brown in colour with a large purple patch on the back. It has fins of variable width, which are usually fairly wide, beginning relatively far back on the body. There are three-pronged cirri over each eye.
Ecology
This cuttlefish is usually found on vertical surface, with its head facing downwards. It is seldom spotted because of its excellent camouflage.
