The attachment pads of parasitic copepods attach to sharks by use of frictional mechanisms.

“The pads probably prevent pandarids from being dislodged by hydrodynamic drag, by increasing overall adhesion. Type I pads are suggested to remove interfacial water and increase surface contact by one of two contrasting methods. The ridges may act as tyre treads, by channelling water from the contact surface. Type I adhesion pads are also suggested to aid attachment by hindering the process of peeling, by which they are thought to be removed by hydrodynamic drag.” (Ingram et al 2006:209)
