Suckers of the octopus hold objects smaller than the suckers by having tiny projections called denticles, 3-micrometer-diameter pegs.

BIOMIMICRY TAXONOMY
Summary
"William Kier of the University of North Carolina is studying the rows of muscular suckers along the arms and tentacles of octopi. Octopus suckers' tiny projections called denticles are 3-micrometer-diameter pegs that provide more intimate contact with the surface underneath. The denticles allow the suckers to grip a range of objects, including objects smaller than the suckers. This could be useful information for creating stronger human-made suction cups."
