| Lattice panels, wires, or rough surfaces give tendrils and holdfasts a place to latch onto. |
| Below them goatfish, wrasses and scorpionfish frolicked amongst the kelp holdfasts. |
| Both of the above forms were found on the washed-up holdfasts of Macrocystis. |
| Crowns commonly have some length of column still attached, and holdfasts, less commonly recognized than crowns, also have some length of column attached. |
| The algae were decapitated, clamped with vice grips at their holdfasts, and secured to the bottom of a unidirectional current tank with an ordinary house brick. |
| Heavy grazing may damage and weaken the holdfasts which anchor the algae. |
