The little cormorant is about 50 centimetres (20 in) long and only slightly smaller than the Indian cormorant (Phalacrocorax fuscicollis). The Indian cormorant has a narrower and longer bill which ends in a prominent hook tip, blue iris and a more pointed head profile. The breeding adult bird has a glistening all black plumage with some white spots and filoplumes on the face. There is also a short crest on the back of the head.
