Algae often relies on spider crabs for a stable habitat, as these crabs can carry algae on their shells, providing a mobile substrate for the algae to grow. This relationship benefits the crabs by offering camouflage and protection from predators, while the algae gain access to various environments as the crabs move. Additionally, the crabs' activities can help in nutrient cycling, which supports algae growth. Thus, spider crabs play a crucial role in the ecosystem dynamics involving algae.
