Polypus wolfi Wülker, 1913
Octopus wolfi, the star-sucker pygmy octopus, is the smallest known octopus. It is found in fairly shallow waters in the western Pacific. It is characterised by a pattern of "papillate fringes" around the edge of the suckers near the arm tip.
Its length is less than 2.5 cm (1 in) and it weighs less than 1 g (0.04 oz). It is found in the western Pacific Ocean at depths between 10 and 100 ft (3 and 30 m).
