Final answer:
The test in irregular forms is covered with different lengths of spines. The covers used range in size and are secured with an anchoring system.
Step-by-step explanation:
The test in irregular forms is covered with different lengths of spines depending on the size of the Caulerpa webbiana patches. The covers used to manipulate and secure the irregular rocky substrates range from 0.5 × 0.5 m to 4 × 18 m. An anchoring system with elastic lines and metal hooks is developed to ensure quick and effective attachment to the substrate.
