Adult sea lamprey Petromyzon marinus attachment strength by the oral sucker was quantified. Surfaces with shallow, rounded discontinuities into which the oral fimbriae could be folded yielded the strongest seal and some fish could control their mouths to improve ‘suction’. Narrow grooves of 1 mm width and 3 mm depth prevented P. marinus from creating a lasting attachment.
