What is the primary function of silk used by black tarantulas in their secure residences?
Answer
To line the burrow for structural reinforcement and to prevent collapse
Black tarantulas, characterized by their fossorial (burrowing) lifestyle, rely heavily on silk, but not for capturing aerial prey like orb-weavers. Instead, the silk serves a critical engineering purpose within their subterranean homes. Both the Brazilian Black and the Grand Canyon Black Tarantula line the walls and tunnels of their dug-out burrows with silk. This silk lining acts as a form of structural reinforcement, helping to stabilize the earth walls and preventing the burrow from collapsing inward due to shifting soil or environmental disturbances. The silk acts as an internal support system, ensuring the security of their hidden domicile.
